"Really accommodating staff, and on flight amenities. I would fly with Delta again."

Pros: "Very friendly thank you!"
Cons: "The wifi login experience could be improved. I purchased wifi as a guest when I had an account and had to spend extra time chatting with an agent to get it resolved. They were very helpful but having the option to login to my account at the start would be ideal!"

Pros: "I would like to have ore of a grace period to check baggage."

Pros: "Crew was polite and very helpful."
Cons: "It would have been great to reiterate to passengers to remain seated when deplaning, until the passenger in the row ahead were approximately 6 Ft away."

Cons: "Bad social distance"

Pros: "Felt safe and sanitary"

Pros: "Delayed"

Pros: "Crew was very friendly and took good care of the passengers"

Cons: "No wifi"

Pros: "The crew went the extra mile to accomodate my bag due to not having a seat in front of me to stow it. Also, Delta Comfort was exceptional!"

Cons: "Smelled like poop the entire flight. Actual poop in the lavatory."

Cons: "We weren't alerted there was a chance of delays. Over two hours late."

Cons: "Better food offerings"

Pros: "Excellent crew and clean aircraft"

Pros: "The crew was communicative and courteous."
Cons: "There was a flight delay in LAX due to a maintenance issue. The captain and crew informed us before we boarded the plane which was excellent. However, they could not figure out what was wrong with the planed and delayed the boarding for another 3 hours, putting our 1900 departure time to 2100."

Pros: "The crew WAS amazing!"
Cons: "Not a thing! It was perfect"

Pros: "Fast flight"
Cons: "In one hour flight we could have some drinks and food. Snacks... can’t believe they don’t have any food/alcohol"

Cons: "More comfortable than I expected for a 6 hour flight. 757 was quite spacious."

Pros: "Nothing"
Cons: "I came from a long trip from France, the seat I was assigned was not reclinable, close to the restroom. I was totally exhausted from the previous flight, not able to sleep at all and when I tried to stretch my legs by sitting sidewards on the aisle a crew member keep bothering me to keep my legs out"

Pros: "Entertainment"
Cons: "Food"

Pros: "Service by crew. I was flying economy but it was par to business class."

Pros: "Nice crew"
Cons: "Delta always delivers!"

Pros: "Very comfortable, no complaints."

Pros: "Yes"
Cons: "Took off late. Other than that very comfortable and great experience"

Pros: "great crew"

Pros: "I really enjoyed the service on Delta. The entire process was better than what i've come to expect on airlines. My flight attendant was Kate, and she was awesome - super friendly, professional, thoughtful."

Pros: "Overall service was great."
Cons: "Flight was delayed 5 hours."

Pros: "If offering free WiFi to Amex platinum card holders it needs to work f"
Cons: "Fix it"

Pros: "Better than average entertainment system for domestic flights."
Cons: "Boarding done against logic: my seat was in the last 5 rows of the cabin and I was scheduled to board in the final group. When I got to my seat the first 30 rows were nearly fully, but the back of the plane was half empty. The whole time the gate agent was urging passengers to move faster through the aisle, but Delta should really rethink its boarding strategy. It shouldn't take 40 minutes to board a 757."

Pros: "Transfer f from first flight leg"
Cons: "Food and the 757 lay out"

Pros: "Snacks that include a dairy free option like the kind granola bar"
Cons: "We were delayed like crazy."

Pros: "The flight was very good, no complaints, good service and we flew on schedule"
Cons: "We were split into two boarding groups, one for priority and one for everyone else. This was good but the priority line was just a bit too far away for the announcements to be heard. This added a little bit of confusion. This was at gate B36 at JFK Airport's Terminal 4."

Pros: "crew kept a great attitude throughout"
Cons: "Having to find my boarding pass to deplane"

Pros: "On time"
Cons: "Take a long time to taxi to the gate & getting off the plane."

Pros: "Clean plane, great breakfast options included with the flight. Crew was polished, helpful and genuinely nice! Gate agents at NYC were knowledgeable, organized, and quick. Boarding was a breeze. Impressive selection of movies for onboard entertainment choices."
Cons: "I thought the $11.00 fee for 30 continuous minutes of full Wi-Fi access was a bit pricey, esp when it kept getting disconnected and ended being about a collective 7-8 mins of access."

Pros: "Fast boarding and complimentary snacks."
Cons: "I was seated next to a very large woman who came over the arm rest onto my seat."

Pros: "Was tired and the FA helped me find a row that I could stretch out on and relax. After a long trip from Moscow, the FA's volunteering to help and accommodate a beleaguered traveler was most appreciated!"

Pros: "The plane wasn't cramped, the flight staff was helpful, and we got to our destination extremely quickly. And they gave us like two rounds of snacks which is unheard of on such short flights. Easily the best domestic flight I've ever taken."

Pros: "What an easy flight. Run very well!"
Cons: "The crew seemed a bit tired, but it’s the season"

Pros: "Seats were comfortable ... enough. Boarding process, once underway allowed me to get overhead bin and stash my other luggage in the seat below me. Flight wasn't overly booked (85-95%) so there appeared to be room for others to stretch out. Now about that crying kid..."
Cons: "Ugh. Weather delays. The flight was scheduled to board about 7P but it arrived late and they had to not only unload the self-loading cargo, but clean up afterwards. Would be nice to get a better estimate as to how long it would take to board so that I could hang out in the lounge. In addition, departure from JFK was delayed as well, either we missed the IFR window or got stuck behind some traffic and I fell asleep on the plane only to wake up what seemed an hour later just getting ready to hit V1. No upgrade."

Pros: "Being on time."

Cons: "Force me to take a bad seat"

Pros: "I didn't get a chance to get the gentleman's name at the gate, but he was able to get me on the earlier flight (since I had NO luggage and only 1 carry on that fit under my seat) and didn't charge me the stupid fee for filling a seat that was empty when I was giving up a seat on a later flight that would accommodate those who missed this earlier flight. Nice to see kindness in an industry that seizes fees on every opportunity."

Pros: "All was quiet. It was an early flight. Nice offer of more snack choices than other airlines."
Cons: "Didn't understand why I had to wait until getting to the gate to have a seat assigned when I purchased tickets several months ago. Since I was in the last boarding group, Had to check in my bag since it was already full, had fragile stuff in there and hoping everything is ok. it is what it is. Not anyone's fault but disappointing to have to do when I didn't plan on checking in and going to pick up at the baggage claim. This is what i wanted to avoid in the first place. could have at least offered to let us pick them up as we deplaned and not baggage claim!"

Pros: "The temp"
Cons: "It was too hot."

Pros: "It got me to SFO earlyish"
Cons: "Was told to go away and wait for name to appear on screen for seat assignment. Was seated apart from travel companion. Got to sit next to folks with questionable hygiene, seat broken. Seatbelt broken. Stuck in back of plane window seat and was supposed to be “happy”. I was brilliantly ignored by crew. Seat back entertainment broken snd flight crew never answered the call button. Got to watch bag handlers throw and drop luggage like true gorillas. Delta, this time you truely are the worst. Wont book you again."

Pros: "Great friendly service and easy boarding. Timely!"
Cons: "For the money they charge, a few little perks such as improved snacks wouldn't hurt the bottom line"

Pros: "We'd paid extra for main cabin so hot to choose seats and got in flight entertainment.. Staff were friendly."
Cons: "No free wifi."

Cons: "Zero communication to the passengers as to why we were delayed for almost an hour sitting on the plane"

"Compared to other US airlines, American is the worst. The planes are tight. Seats are uncomfortable and there was no option to buy food on a 6 hour flight. Also the free wifi didn’t work."

Pros: "Bast trips!!"
Cons: "Evriting is good!!!"

Cons: "Enforcement of federal rules requiring children two and over too wear a mask. Flight attendant did not believe it was her responsibility to ask the age of the child sitting next to us, sneezing and coughing."

Pros: "The crew.was so rude, even from the check in process"
Cons: "Everything,"

Cons: "Sick joke of an airline they treat you like cattle even in first class if you can even call it that. It’s more like premium economy and the staff is not friendly they act like they are put out when you ask for anything."

Pros: "Crew and service was solid given the covid restrictions."

Pros: "Literally nothing"
Cons: "After sitting on the plane for over an hour we had to change planes. Notice that our aircraft isn’t working properly before you board it would be helpful so we aren’t 2 hours behind schedule having to sit on a hot airplane during covid"

Pros: "Flight attendant was very fun. It was her birthday and made the day fun for everyone."
Cons: "Seats are always too close together - left to right and front to back. A sad reality that only improves for the well-to-do."

Cons: "Traveling in a 737-800, there is no displays at your seat. One must BYOD. Wifi was spotty."

Pros: "Crew was amazing, seats were comfortable. Only negative is out of your control - bad weather in DFW held up departure 5-6 hours. Much of that was on the plane, but crew kept us notified. We had to return to the gate and wait another couple of hours. Awful trip, but not your fault. What I was surprised by was no comp hotel, and the discounts were not rally good discounts."
Cons: "Most of my issues were ATC problems, not AA. The AA personnel kept us informed, etc. The one thing you can control is hotels if delayed to the point of missing all connection until the next afternoon. I understand not compi9ng BUT, when google maps shows better rates at local hotels than your "discount" program, that's sad."

Pros: "Great crew"
Cons: "Snacks"

Pros: "Again the flight did not happen since my flight from Munich to Dallas was cancelled without informing me why and so on."

Pros: "Crew was attentive and accommodating for seats due to virus."
Cons: "Delays could've been prevented or let passengers know, instead of being on the plane for 2 hours without moving."

Pros: "Crew was very hospitable"
Cons: "Flight was a little late taking off, so punctuality could have been a little better"

Pros: "The crew serving the plane didn't look like they wanted to be there. Somewhat abrasive. The entertainment was poor and not very easy to access through your mobile, Iphone and Ipad. If you want to provide a better customer experience, equip all your planes with seats video screens. Passengers on a 4 to 5 hours flight don't want to have to figure out what do to watch a movie or TV. I don't fly American that often, but wanted to give it a try to see the difference between you and the other airlines. I have to say that on the return segment (ORD to SFO), I was not that impressed."
Cons: "See above"

Pros: "Slight delay in leaving"
Cons: "Baggage claim took 30-45 minutes after deplaning"

Pros: "Crew were very helpful"
Cons: "I have an injury so I paid extra for 'extra leg room" but there's a wall between economy and business class so very little legroom. My leg was hurting a lot and the flight attendants had to find me a different seat because I could not stay there for 5 hours. I wouldn't have paid extra for this seat."

Cons: "4 hour delay for no reason! I’m never flying with American Airlines again!"

Cons: "On Time. Delayed advice 3 times."

Pros: "They had the AC on while we were waiting on the plane at the gate for 1.5hours"
Cons: "That the flight was delayed for 2 hours, information was inaccurate/missing, they knew we'd miss our connections but did nothing except, "they'll deal with it in San Francisco" and when we landed there was no one in sight to help us--no escorts/expedite to gates, no one to tell us where to get rebooked, and after going back and forth between terminals, waited in line an hour to get rebooked on a series of flights that would get me in 22hrs later after my original flight."

Pros: "No flight. It was cancelled."
Cons: "Find a sooner alternate flight"

Cons: "If we had access to the WiFi to watch shows earlier like United does, that would be nice."

Pros: "The flight and cabin crews handled an equipment problem and consequent delay, and information about it, very well."

Cons: "salt free option for snacks; flight could have not been delayed but that’s not the flight crew’s fault. winds at sfo caused us to delay our takeoff"

Cons: "if the crew/flight wasn’t filled with racist tendencies that forced a black man and his partner to take a new flight because his “tone” wasn’t to their liking when he responded to accidentally being the wrong seat, costing us 90 minutes at least of delays because they deplaned us all when all."

Pros: "Everyone was nice and it went smoothly!"

Pros: "The flight crew was quite lovely."
Cons: "People all over the coach section were complaining about not being able to sit together. Families with babies, couples, even ours (though the kids are old enough for me not to be truly worried as some were). Somehow reservations seems to have messed up an entire flight. We gave up trying to fix it for fear they would make it worse. Then the woman at the gate tried to get folks to volunteer to give up their seats on an overbooked flight. But she was screaming at us. Unbelievably unpleasant to be yelled at over and over again and told we could lose our seats. The poor weather likely caused flights to be rerouted into PHL so our flight out to SFO ended up 1/3 empty. FABULOUS. But the gate experience was horrible and the legroom, had it been a full flight, was miserable. I'm in search of an airline with a humane approach."

Cons: "The flight was delayed. The food was not great. There is not a lot of space in these planes, and it was a long flight. There is no power supply."

Cons: "Because they canceled my flight and i had to buy another ticket for 380$ and after that I realized my chair was available and i took a picture. It was really bad and i never choose again American Airlines."

Pros: "nothing"
Cons: "no inflight entertainment no outlets"

Pros: "Very nice crew. The flight attendants were very patient and efficient. Flight was very smooth and surprisingly not overcrowded. For the first time, in a long time, when getting off of the plane it was very organized and not everyone rushing and pushing to get off. Everyone followed suit and did row by row, and no one pushing or shoving which is always nice."
Cons: "The only this I would suggest is that on a longer flight you should offer better deals on food/snacks."

Pros: "Plenty of leg room."
Cons: "No arm room when someone the size of an NFL player sits next to you and falls asleep with their arms relaxing into your space. Then they sleep open-mouthed with bad breath. I paid extra for that?"

Cons: "Seats were quite uncomfortable, there was no entertainment options, there was no way to charge any electronic devices because the plane was so old, which meant I almost wasn't able to catch a ride home after the flight. For a cross-country flight, I would expect a better experience."

Cons: "No leg room"

Pros: "Flight was on time."

Cons: "For a flight five hours or more I was disappointed that there was no complimentary food. It otherwise it was fine"

Pros: "I really enjoyed the movies on this flight and they had us change to better seats before we took off"

Cons: "This was my first time flying First Class. Not only was my flight delayed but everything was changed last minute. My seats, layovers, EVERYTHING! I was better off paying for a regular seat. I'm a young African American and the stay treated me as if I didn't belong in First Class! Not to mention the last time I flew into LAX American Airline lost my luggage! I have proof to show! Absolutely ridiculous!"

Pros: "The plane was comfortable and flight was smooth."
Cons: "The shuttle to the plane wasn't bad, but would prefer not to have that element included."

Cons: "No room, limited entertainment, mediocre food. Was a very uncomfortable, long flight! Luggage late coming off plane, missed connecting flight and was not very helpful in getting rebooked."

Cons: "Again American Airlines was LATE. It was boarding time and no agent was at the gate. 10 minutes past boarding time the screen shows that the flight is delayed 25 minutes... but wait, there is still no plane at the gate! After 45 minutes the plane arrived, again had to be "cleaned" and prepared for flight back to SF. Customers were told the flight was delayed because Air Traffic Control issues in SF, but there was no plane in sight... Again I felt we were being lied to. The plane was filthy with garbage everywhere still. I will never fly American Airlines by choice!"

Cons: "People still using mobiles as we were taking off. Crew seemed not too bothered."

Pros: "The flight was >1 hour late, which the pilot told us was due to the LAX controllers changing the landing patterns due to weather. So this really wasn't anyone's fault. But there was a large difference in comfort between this flight and the JAL flight from Tokyo. Seats were smaller, and my wife and I couldn't get seats together."

Pros: "Had a airline steward named Scott that was very pleasant and nice all throughout the flight."
Cons: "The plane was late/delayed going from Dallas to Colorado and the plane going from Colorado back to Dallas was late/delayed as well ."

Cons: "My flight was delayed for 3 hours and they where rude about my flight being delayed"

Pros: "The crew was able to seat my husband and I together at the last minute as my husband has mobility issures"
Cons: "The crew seemed like they could care less about the passengers. Choice of either one snack bag of pretzels or a biscotti ~ very minimal. No headphones were offered for the movies."

Pros: "How the pilot was insistent on the idea of taking off and flying, although we were informed of two system error messages, alledgedly the first for an issue with the AC, the other regarding the drain system. After our return to the gate for the second warning, I deplaned. Didn't feel safe after that!"
Cons: "Same as above."

Pros: "I liked that the seats had chargers (even though I didn't need them) and that they offered entertainment."
Cons: "Boarding was over 30 minutes late which ruined my SF plans. The crew was mot welcoming walking on or off the flight. They were also very rude when serving, one even gave me a super nasty look and mumbled something under her breathe because she ran into me. Just a terrible experience. They also didn't tell me baggage prices when I was there just swiped my card."

Pros: "The crew was very nice and competent and obbiously embarrased by whoever in operations screwed this flight up good."
Cons: "Pleane departed two hours and thirty minutes after original schedule because of operational and equipment problems. Plane wasn't even in Philadelphia unti 6:00 pm. The guy at boarding (unlike the boarding in SFO) called way too many groupss individually, First Class, Diamond, Premium, Gold, Priority. This led to many people being refused boarding and told to wait. In SF they simply call first class and then all the rest or the Aadvantage members together before the land boarding. Much faster and more efficeint. Even though the flight was full there less than 12 people in the Diamond, Premium, whatever classes. And the guy taking the boarding passes was a jerk. He actuallly seemed to take pleasure in telling people they couldn't board. Might not ever fly AA again. At least never from Philadelfphia."

Pros: "That the pilot got us home safely."
Cons: "Honestly I am not a big fan of AA. I made a mistake booking my flight but couldn't change it because it was going to cost an arm and a leg. The staff are rude and don't try to help you. It's just a job for them to get by and it shows. Many including myself isn't big fans of AA. I wish this airline gets bought out by Southwest who understands value and elite customer service. They don't charge every little thing like American. I hope soon they can fly into Colorado Springs."

Pros: "We like the boarding according to row n., which limits the contact with other people."
Cons: "The plane was full, which means no physical distancing was possible."

Cons: "Clear checkin needs to have better coordination with TSA agents."

Pros: "Boarding was very smooth"
Cons: "Crew was late arriving to what would have otherwise been an on-time flight"

Cons: "the seats are very uncomfortable."

Cons: "Leaving on time, or not being boarded until we were actually going to leave. We sat on the tarmac for 3.5 hours while we were hungry and thirsty. The communication was poor overall on why we wouldn’t leave. Terrible flight."

Pros: "Nothing. United has a long way to go."
Cons: "Food is terrible. Honey nut cheerios is the only cereal choice, great for diabetics."

Cons: "We should have had less in our carry on so we had more leg room. The staff was friendly and very helpful. There was plenty of movies, tv options, and games to pass the time when we weren't sleeping on the over night flight."

Pros: "Read above"

Pros: "Nothing"
Cons: "Service. Made us late for connecting flight."

Cons: "United have somehow managed to make their newer planes (777) even less comfortable then their old ones, I thought that was impossible but they found a way."

Cons: "I was traveling with two kids and they used my phone for shows and I brought another older Oppo phone for the myself. It just wouldn't work with the united app to open up the movies. Was unfortunate because I had two flights."

Pros: "The crew and the fact that they at least acted like they cared."
Cons: "After UA posted a four hour delay for my original flight, I switched to the next available 1.5 hours later. That flight got delayed and then delayed some more, and by the time I got to SFO, the flight I originally booked, landed about 20 minutes later."

Cons: "Flight was 65 mins delayed due to mechanical issues. Updates came from flight attendants insisting gate agents update the flight status."

Cons: "I didn't go on my trip. My course in SF was cancelled and United would n't refund my money or change the dates for my trips because of there basic economy package. They have 3 different economy packages and the economy basic doesn't get refunds and you can't change the flights if needed. It feels like they are banking on increasing there ROI with this basic economy ticket which is 40 -60 dollars cheaper than the next economy package. Intuitively they know people will pick that, but if something comes up the customer is screwed."

Cons: "Hold time on tarmac. Over an hour. In a hurry to board people. If they knew they had a delay due to weather they might have done some better planning"

Pros: "Cool crew"
Cons: "Delayed flight"

Pros: "Got an aisle seat"
Cons: "Plane was late. No Wi-Fi."

Pros: "I enjoyed my interaction with the other passengers."
Cons: "Several delays compounded to make trip a lot longer and far less comfortable than it needed to be."

Pros: "Nice seats, very helpful staff at ticketing and nice crew"
Cons: "Reservation was deleted so check in took a very long time and my seat (reserved weeks in advance) on the long international flight was reassigned to a very undesirable location."

Pros: "After a 2 hour delay we boarded to free DirectTV. Thanks United!"
Cons: "Gate agent, grumpy. Some how she thought it was my fault they offered me a cheap ticket to purchase. Regardless of the price I, or anyone else pays, we should all be treated equally with dignity and professionalism."

Cons: "I was charged twice for my ticket"

Pros: "Friendly crew"
Cons: "Sardine can with no amenities. What value."

Pros: "Nice Hosts?"
Cons: "Cant watch TV for free- stuck watching gold rush whatever that is. Seats were uncomfortable knees felt cramped up smelled funny could not sleep, because the seats were not comfortable we sat at the gate for too long we took off late why didnt we de-ice beforehand? I dont understand why they say "we need to check your bags" when there is plenty of overhead space. It's stupid"

Pros: "I like that this flight got me from point A to point B. It was uneventful."
Cons: "I am tall and there is never enough leg room"

Pros: "Chief flight attendant was nice and attentive."
Cons: "Our section of the plane was very warm. When we mentioned it to one of the attendants, she pointed to the overhead vents and told us to use them. (We already knew this and had them open all the way!) Then the chief flight attendant came by and she was VERY responsive and went to tell the pilots. It got a little better but still stayed on the warm side the rest of the way. Your boarding process makes no sense and does nothing to get passengers settled faster. After priority seating is done, let the people in the BACK of the plane board first, then the middle section passengers, then the Eco Plus passengers."

Pros: "There was a mechanical delay that caused us to leave 1.5hr late. The gate team did a good job keeping us informed of what was going on."
Cons: "Delay kept changing as they tried to fix the problems. Also, wifi did not work so I couldn't use free United entertainment via the app."

Pros: "Nothing"
Cons: "Our flight was delayed which caused us to miss our international connection. Flight attendants did not care, did not attempt to get us out faster, or put on a different flight. Asked for an announcement to be made on board or to be moved to seats closer to the front so we could get off the plane quicker, did not happen. Offboarded and sprinted across the airport for our international connection and was notified by gate attendents that the gate closed five minutes ago and that they could not let us on the plane. Meanwhile, the plane sat there for an additional 30 minutes while it fueled and waited for release from air traffic control. There were six travelers total stuck there in San Fran at that gate, all of us begging to be let on the plane to Beijing, the last one for over 24 hours. Zero compassion from staff at the the airline gate. They did not care about us and did not care about leaving their travelers stranded. Our total travel was Denver to Bangkok, 26 hours of travel including layovers in San Fran and Beijing. In San Fran (after missing the gate connection), United rerouted us through Haiwaii and the customer service agent that did this reroute did not finish the reroute to our final destination. We got to Haiwaii and were stranded again, at the United service desk for four hours having to once again provide documentation of our initial travel plans to Bangkok, having them build a new itinerary to our final destination. Overall, 20 additional travel hours have been added to our itinerary, almost double our initial travel time. We have had to call and cancel pre-arranged bookings in Thailand as we are now missing two full days off our trip. I am absolutely disappointed and heart broken as I write this still stuck in the Beijing airport waiting another six hours to connect to Bangkok. My fiancé and I were traveling to Thailand to get married and have received no compassion from anyone at this airline to try and get us there. I fly United for work quite frequently and have never experienced such horrendous service and lack of basic human compassion. I am flat out disgusted by United and will not be using them again, for personal travel or work related trips, because of this horrendous experience."

Pros: "Crew did a great job. Air China had much better food service."
Cons: "Seats two small, not enough room to stretch your legs. Bathroom to small. Designed for people less than 150lbs, and 5'-6" in height Not comfortable for people over 6' tall."

Pros: "It was a brand new aircraft in it was a big one."

Pros: "The stuff were accommodating and fun"

Cons: "Seats in economy were cramped! Chair barely leaned back at all. Woke up with a sore neck. Cabin was freezing!"

Pros: "Price was good. If it'd been an expensive ticket I'd have been upset"
Cons: "Pay for carry on luggage, last board plane despite having a window so everyone had to get up to let me in, no check in 24 hours in advance unless paying for baggage, in flight entertainment didn't work, seat charging outlet didn't work."

Pros: "Seats were comfy and I liked that the screens on the back of seats had a map of where we were in the flight."
Cons: "Wifi was kind of expensive- I bought 30 minutes for like $3- but it didn't even work. Maybe got 5-10 minutes of actual internet out of it, the rest was frustrating loading pages. Not worth the purchase."

Pros: "Nothing"
Cons: "Couldn't even get me a slightly better seat given all the hassles I'd been put thru up to that point."

Pros: "Flight was shorter than expected"

Cons: "United king of being delayed.."

Pros: "Na"
Cons: "Flight delayed 11 hrs, they could not offer me an alternative to get me to my event in time so after five hours at the airport I had to return home. Their offer was "maybe" a refund and a $10 food credit. Out $500+ lost in hotel fees at my destination- which most importantly, was my ten year grad school reunion!"

Cons: "EVERYTHING. My flight was originally scheduled for 650p. I understand that weather can cause delays. That's OK. However, the flight departure kept getting shifted. We ended up boarding for a 9:58p departure. I was told there was no more overhead space for my bag and forced to check it. When I got on the plane at 930p, there was clearly enough overhead room for my bag. I'm not sure why I was forced to check it. We then sat from 930p to 958p. We pulled away from the gate and then were told that we had to wait another 20 min. We turned off the engine and then waited until sometime between 1130-45 ON THE AIRPLANE on the runway. Is this even legal?? We finally took off and landed at 115a PST. I waited for 35 min for my bag that they forced me to check. They loaded our bags onto the wrong carousel, which caused all of us to be waiting for our bags in the wrong place for 10 minutes. This was the worst experience I've ever had flying. It wasn't the delay but the lack of clarity, being forced to sit on that plane for hours, and having my bag taken. I got to the airport in Denver at 550p PST and got home to SF at 3a PST for a 2 hour flight."

Pros: "nothibg"
Cons: "ecerythung"

Cons: "Power outlets worn out and won't hold a plug so they are unusable"

Cons: "The stewardess was very hard to understand in English."

Cons: "Entertainment system was extremely poor. Need app to use it so I didn't preload onto my iPad but tried to use iPhone instead and the streaming was just so poor and kept freezing that I just gave up and read a book. Also selection should have included a lot more shorter programs that could be viewed on less than 2 hour flight eg lifestyle programs, news etc."

Pros: "Got to sfo early which I always appreciate"
Cons: "Boarding took about an hour because people didn't seat in their assigned seats and the flight attendants didn't notice until a family who had purchased seats together found their seats occupied. About 8-12 people had to switch seats, absolutely ridiculous"

Pros: "Left in time"
Cons: "The plane was so unbelievably hot. The air hardly blew out of the vents. Also, they left the lights on the entire time on a flight that left at 10pm and arrived at 12:30pm (11:30pm local time). It made for a very uncomfortable ride"

Pros: "Free wifi, one free snack and drink, overall one personal item and one free carry on bag."
Cons: "Wifi wasn't excellent and the crew should tell the passengers that they give out one free snack and drink."

Cons: "Waiting, wondering, waiting, wondering, being cold. Mechanical problems led to long delays, the whys, how's and when's told to us were confusing. Arrival delayed from about 10 pm to about 2am. Affected the sleep before a workday of the family member who picked me up. Felt like a victim of United."

Pros: "The employees were very helpful on both legs of the journey and the conneting flights were conveniently located in the same area. Pilot was good about letting us know time frame of mechanical issue repair while on tarmack."
Cons: "The seats were incredibly uncomfortable. Must be the type of plane because never really had issues on other flights. We noticed many carry on bags others brought on bosrd were oversized. On leg from Kalispell to Denver the crew were diligent in spotting larger bags and tagging them for under plane storage for the flight. From Den to SFO however not so much. This led to most bins being filled ahead of our group 4 boarding with larger than permitted carry on bags. Obviously larger! Luckily we were able to put our smaller bags (which we made sure fit to overhead storage specs ahead of time) under the seat for flight but that made an uncomfortable 2.5 hour journey. Actually over 3 hrs because there was a mechanical problem which had us sitting on the tarmack for over 30 minutes from Den to SFO. We've flown United before without much incident but this trip in particular was pretty crappy."

Pros: "Night flight. Impossible to sleep with so many devices on."
Cons: "The screen button is on the armrest and gets turned on inadvertently constantly disturbing our sleep."

Pros: "it delay 9 hours."

Cons: "Very crowded feeling and I don't have claustrophobia. My seat in the very back couldn't recline because it was jammed in with less legroom than others around me."

"Never happened. Plane left while we where waiting for a gate. Poor planing at its best. And all you can do is a 10 dollars for a meal for a person who's flight was delayed twice and was left at the airport because of your negligence not weather."

"Frontier seems to be trying to be a good airline. Gate communication and baggage checkin are weak communication points."

"The boarding staff were rude, and the in flight staff consistantly peddled their credit card"

Pros: "Amazing crew all around. Everyone that I encountered that worked for Frontier was friendly and helpful. I wish every check in/boarding/flight was that well organized."
Cons: "The seats are teeny and the new tiny tray tables make lots of noise. Lots of hidden fees. Delayed flight"

Pros: "Clean, on time, reasonable"
Cons: "do not sell the middle seats"

Pros: "I thought everything and everyone were great!"

Pros: "On time. Professional. Clean."
Cons: "Nothing. As expected"

Cons: "Don’t let people get on the plane and then tell them there’s mechanical issues and they have to get off. Is there not a safety or functionality check before we get on the plane?? Giant waste of everyone’s time"

Pros: "the crew was very welcoming"
Cons: "1the seat was extra super uncomfortable. There was a big metallic box under the seat in front of me so I could not extend my feet or put my personal purse under the seat. The space for my knees was very limited. I did not understand the entertainment options. II d had to pay for moveis on my phone?"

Pros: "Good"
Cons: "Good"

Cons: "that it cost $45 per bag whether you used baggage shipped or carried one. Was then told if did,t pay it at counter, would cost $60 upstairs to carry on. Would only use airline as last resort due to this tactic"

Cons: "They didn't know how to handle the unpleasant situation of having delay due to "the plane is having some problems and they will try to fix it asap before departure"."

Cons: "When I bought the tickets, I didn't realize a carry on luggage is and extra $45. That's $90 added to the ticket price. Buyer beware"

Pros: "Clean new planes and very friendly crew."
Cons: "It got delayed on my inbound trip for over an hour and a half for no real reasons (all were excuses: weather, crowded landing at SFO, air traffic controller did not give the green light, etc.). On the way back we had to wait over 45 minutes for the plane in our gate to move out of the way so we can get in."

Pros: "I arrived at my intended destination."
Cons: "They charged me for a CARRY ON which no other airline does or has ever done and they don't tell you until you're at the gate. It cost money to check a bag, so I didn't but it costs double to bring s carry on which seems like a manipulative, strategic move on their part. Awful frontier. Just awful."

Pros: "price"
Cons: "Flight delayed 7 hours. Called the airline after receiving a flight delayed text, and before heading to the airport, and was told to get there by 5pm because the flight may leave on time. Departed at 2am on a Sunday night instead of 7pm. Was told 3 different stories for the delay. Departing airport weather, although blue skies and all other planes taking off on time; plane arriving from an airport that had grounded all flights when Frontier was departing to said airport as they reported this story, mechanical failure, etc. Took a picture of the departures board where all other airlines were departing on time to all locations. Asked if food vouchers would be provided and told, "no". Then vouchers were provided 2 MINUTES before all restaurants in the airport closed. The vouchers had a print time of 4 hours earlier. They would not rebook on another airline and would only rebook on Frontier 3 days later. Zero customer service. Employees were rude and complaining that they had to work late while their customers would be arriving home at 5am after booking a flight that would have allowed time to sleep before work. This is on top of no carry-ons, entertainment, or even water on the cramped, packed flight."

Pros: "Boarding was fine. So there's that."
Cons: "No one was available to deal with missing luggage. Took more than 45 minutes after carousel stopped spitting out bags for us to find an employee who'd talk to us. They couldn't find proper forms, so they jotted down our info on scrap paper. Made no effort to clarify where the bags had gone. When we asked what to do if the bags remain MIA, we were told "there's a number to call" – it took three requests to get them to provide that number. They even lost a gate-checked stroller, which is very sloppy and a huge inconvenience for the passenger. The employees we dealt with were uninformed, unconcerned, and unprofessional. Airport worker at nearby info desk says she sees this scenario play out all the time. I will not fly them again."

Pros: "Ticket prices were initially really low."
Cons: "Everything else about my experience with frontier. They nickle and some you at every corner. When you go to pick a seat that'll cost you $5-$25 per seat. Then you're looking at $35 per checked bag $40 PER CARRYON. The only time I have ever paid for a carryon bag. No complimentary water/beverages/snacks. The seats are hard plastic with very little padding and no reclining. The tray table is smaller than your average tablet. On our departing flight we sat on the tarmac for well over an hour with no explanation. Horrible customer service all around. I will never be flying frontier again."

Pros: "Arrived 40 minutes early so can't be too sad about that especially since a gate was available immediately. Jet bridge in SF was heated but in Denver where it was colder and he had to wait it was not. The check in lady clearly did not care about her job at all I'm Denver. Frontier is a budget airline which for this trip worked for me as I was able to pack everything in a "personal item" and don't mind sitting in the back of the plane, I got lucky and got asigned a window seat. No drinks offeed without a charge which I don't agree with but again you get what you pay for. And it's way better than Spirit."

Pros: "Crew was pleasant"
Cons: "They charge for: a checked bag, a CARRY-ON bag, and your seat choice. There is no on-flight entertainment. The seats don't recline. The check-in counter has massive lines of people and is clearly understaffed. The gate is frequently empty and abandoned with zero people to answer your questions. Flights are late without good reason. Gate agents are understaffed, uninformed, and frazzled. Gate changes were poorly communicated and disorganized. Frontier management and leadership: you should be embarrassed."

Cons: "They charge for everything, even carry-on! If you don't tell them you have a carry-on, they will charge an additional 20$ on top of the $40 for the regular charge. They charged me even to make a check-in online and assign a seat. Only water is served in the plane and if you want soda you gotta pay for it. Ridiculous! The counter crew are rude and seemed overworked. The airplane seats DO NOT lean back and they have no foam, only a hard piece of leather covering the metal seats. They put their price very low on the travel websites and get you that way. Later on the fine prints (which no one ever reads, btw), they state that there are extra charges for everything else. I am surprised that they didn't charge me to breath inside the plane! Im Chocked!"

Pros: "The flights arrived earlier than scheduled. The crew was pleasant and in good spirits."
Cons: "Very uncomfortable plane; I was told I had to put my bag under the seat in front of me rather than in the overhead bin which was annoying mostly because there was no legroom to speak of as it was and the tray tables were ridiculously small. The employee who checked me in told me I had to pay $15 extra for a window seat, but after everyone was on board, there were 20 empty seats. It would've been nice to offer those seats to other people on the flight so everyone could spread out a bit."

Pros: "I liked that the plane flew safely."
Cons: "Both my flights were delayed which caused a lot of inconvenience given that this was a short trip and time was of the essence. The second time I kindly approached the counter to ask if a drink ticket or free wifi could be extended as a courtesy. The woman at the counter was snarky to me and made under her breath comments as I walked away. I understand now that frontier does not have wifi but she was very rude. I think this was the tipping point for me. I was trying to be ok with the unexpected charge for a carry on. I think letting passengers know in advance would serve in Frontier's best interest since this is an incredibly unusual charge and one I have never heard of from any other airline. The people at the counter who explained this to me as I checked in were also rude and snarky. I felt that Frontier provided absolutely nothing past a the actual flight. The seats dont recline, not even a centimeter, the tray tables are too small to place a drink and a sandwich on it and it seemed every Frontier flight in the airport was delayed. The icing on the cake is how nasty the customer service people were. I've experienced rudeness from other airlines before, but at least we landed on time and I didnt suffer back pain for 2 days afterwards from the incredibly cheap lawn chair style seats. Please improve your service. I know your whole bit is you wont provide any amenities so you can pass down the savings to the customer but it's not really a cheaper flight if when you get there you have to pay an extra $60-80 for a carry on?! Grow your company, provide outstanding service and pay your employees enough that they dont behave like they're at a dive bar. On the upside I do believe the pilot was sober."

Pros: "Boarding went fast, thanks to zones and smooth travellers"
Cons: "Leaving late, seats not reclining at all, lights out the whole way. Took Frontier SFO to Denver 2 days prior to this trip and had s 4.5 hour delay."

Pros: "Nothing"
Cons: "At airport 2 hours before flight and still missed flight due to check in lines that were the length of the entire terminal. Knowing the capacity of planes and number of booked flights, one would think they would have more than 4 people working the checking in counters. Did not receive a refund for flight and baggage fees. I will NEVER Frontier again!"

Pros: "Price"
Cons: "You risk losing the flight unless you pay additional fees to select a seat in advance. If you do risk getting your seat assigned at the gate (no fee), you MUST be first to the gate to get your seat assignment because they far oversell the flight. Interestingly, they seem to intentionally punish people who avoid the seat assignment fees in this way. My evidence for this is when my husband and I were first in line at the gate for a seat assignment, the agent said that there were no seats together and gave us seats far apart. However, the girl behind us in line ended up sitting next to me, meaning that the agent purposefully seated my husband and I apart. In addition to all this, you must pay for SODA. And there is no entertainment, as the seats are thin plastic and squished as close together as possible. Consequently, the seats have laughably small tray tables. In summary, I will never fly Frontier again."

Cons: "For starters what is the point of paying a $400 ticket if I have to pay for a seat again?? This makes no sense. When i board i noticed the tray sizes where cut to 3/4s of the original size, and the seats where plastic and VERY uncomfortable. I am 5 feet tall and even my knees were cramped. TERRIBLE airlines. NEVER will fly Frontier again."

Cons: "1. They charge for every little thing. Each checked bag is $25.00 and each carry on is $35.00. They also charge you for a seat. So once you purchase your ticket, you then have to pay an additional fee to seat down. 2. The staff is unprofessional. Not only does everyone look sloppy, but the staff is comprised of individuals that don't care at all about customers and have been poorly trained. The quality is very low. 3. I was hit and then verbally abused by a gentlemen on the plane, they laughed and did nothing!!!!! 4. They only allow 15 bags on their plane! After 15, they will move your bags to a different plane without telling you. What kind of nonsense is that?!"

Pros: "What a cheerful and fun loving crew! They were accomdating and friendly. I had an unpleasant experience flight from SF to Denver but completely different experience to SF! I want to thank you for the fun crew from Denver to SF on 9/3/16 9:05pm flight!"

Pros: "The minimal interaction I had with the Crew suggested that they were nice."
Cons: "It was continuously delayed a total of five times. It was not explained why things were delayed. The spaces were cramped and the trays were small. Leads me to be interested in traveling in other "cheaper" airlines such as Spirit."

Pros: "Arriving at my destination."
Cons: "Paying for a ticket then having to pay for a seat on top of that as well as having to pay for a carry on bag. No complimenary beverages or snacks. No entertainment or wi-fi, even to purchase. Disorganized and unhappy crew. Worst flying experience from any airline I have been on."

Cons: "I was seated between an overweight man and a very tall man, both of whom felt as though their sizes allowed them to infringe upon my space. There were plenty of open seats on the flight and yet no effort was made to alleviate this clear problem."

Pros: "Nothing"
Cons: "Everything from getting charged for each bag, uncomfortable seats that didnt recline Delays with getting our baggage. No entertainment on board. No snacks on board The worst was on our way back from Denver to SFO, long delay our flight departed nearly 2 hours late, and the flight crew breached the instructions for flying before take off. I will never fly Frontier again"

Cons: "Yet another delay in leaving (unrelated to weather from what we could determine)... Arrived in San Francisco at roughly midnight instead of 9 pm."

Pros: "The flight staff was really nice and provided excellent customer service :-) I felt sorry for them that they had to work for such an incompetent airline and field so many customer complaints."
Cons: "In response to Frontier's survey question, "How could we serve you better?" Be more transparent about your hidden costs, and be sure there is a gate available when you land. There were delays coming and going. In Denver we sat on the runway for at least 20 minutes before we found a gate and could get off the plane. In SF we sat on the runway for over an hour (!) with the engines running. My throat was sore from breathing carbon monoxide fumes. The friend who came to pick me up in SF was kept two hours past her bed time because that was the totally amount of delay. To add insult to injury, you had the nerve to CHARGE for coffee, and worse I paid $160 in baggage fees round trip, making you MORE expensive than competitors, not less like it appears when you buy the ticket. I did try to look up your baggage policies on line and by phone (which referred me to the website and gave no option to speak to a person), and it was not easy. The only information I found before I lost my patience was that we would be charged more if our bags exceeded certain limits. The original charge was cryptic and hard, if not impossible, to find. We were told both coming and going about staffing shortages and employees calling in sick. If you treat your employees like you treat your customers, no wonder they don't want to come to work! Not only will I NOT recommend Frontier to my friends, but I will go out of my way to DISCOURAGE them from flying your airline."

Pros: "I booked Frontier for the low price. But after going to a farther away airport and paying for bags and seats and drinks and sitting in an uncomfortable seat, I am not so sure it was a great deal. I am happy that I did pay less than other airlines even with the cost of checking a bag (less cost than carrying one one) and for the seat. Because it is more costly to carry on a bag, hardly anyone did leaving lots of room in the overhead compartments and speeding up boarding and deplaning considerably. Snacks and drinks were reasonably priced and lower cost than in the airport. Only snacks like chips and beef jerky are available so if you want food, bring your own. Flight attendants were friendly. My bag arrived on the same flight that I did and it was in good condition. We were reasonably close to on time."
Cons: "Seats are short front to back and don't recline. There was barely enough room between seats to force by backpack down to the floor and almost no room on the floor to hold it leaving me with no where to put my feet except on top of it. My legs are long and about 1/2 of my leg was not supported by the seat. This was manageable for a short flight but I would certainly not book a long flight with these seats. We spent considerable time on the tarmac waiting at both ends. I am not clear on the delay at the beginning of each flight. The delay at the end was related to Frontier only having 1 gate at each airport so we had to wait until it was free. Yes, we landed 20 minutes ahead of time, but we got into the gate 20 minutes late - meaning sitting on the tarmac for 40 minutes. Bags were slow to come up. Probably because everyone checked them so there were many."

Cons: "Boarding - people who sit up front go first meaning that those that have seats in the back have to go in past people who are still in the aisles arranging themselves. I could not get a drink of water without paying. Is it really that esxpensive to give a coke and some peanuts??? Paying for seat selection means that some people get in the seats other peoiple want (like window seats) who don't want them. I tryly believe that Frontier is the nickel and diming airline. And I don't believe you had to wait for a gate and 11:30 at night."

Pros: "Easy check-in."
Cons: "Hidden charges for carry-on luggage was an unpleasant last minute surprise and added an unwarranted $55 to the cost of the flight. Had I known the flight really wasn't the advertised price, I would have picked another carrier because their price would have included everything. Frontier seems to charge for every little thing but the air you breathe in the cabin. I suppose that will be next. Frontier used to be really good and now it is aging planes, unhelpful staff, and nickel and diming their passengers to death. Next time we will fly with another carrier."

Pros: "That they got me to my destination safely."
Cons: "This airline is a joke. Shame on me for booking late and choosing the cheapest ticket. BUT knowing what I now know, I would have selected the Delta flight for $80 more. Here's why: No TSA Pre-Check. This aspects alone is a deal breaker. Pay for carry-on bag AND IT COSTS $40. Pay for beverages, snacks. Seats don't recline - "pre-reclined for your maximum comfort." Whatever Tray table is metal and tiny. You couldn't even fit an iPad mini on it, let alone a lap top. So, I put my MacBook on my lap to work, but it's uncomfortable, MacBook slides off. You're hitting the person next to you with your elbows. AND I have to take off my jacket, to protect my MacBook against hitting the metal tray table, so I got cold. No internet. It's 2016. No internet. It's 2016. Never again."

Pros: "flight staff"
Cons: "OUTBOUND - confusion for me and others as gate changed and we had to go to international for domestic flight - thought it strange to suggest I pay additionally for a seat and a carry on. RETURN - again confusion for me and others as gate changed and no gate personnel at kiosk for quite awhile They don't even give a pretzel snack on these flights."

Pros: "Staff wasn't terrible"
Cons: "the flight was only cheaper until you had to either check a bag or pay to carry on! Pay to drink a soda or anything! The seats are the most stripped down uncomfortable airline seats I have ever experienced. After all the add on costs, there is no value in the cramped, crowded, uncomfortable flight. Also, on every flight at least half of the passengers were not aware of the baggage policy until it was too late to check it for less money and had to pay extra to carry on."

Cons: "Terrible flight delays, due to plane maintenance missing our connecting flight. Only after speaking to several people were we able to get a ticket on the next flight. We were offered standby and a ticket on the flight the next morning. They would not schedule is with another airline as they were not affiliated with any one. And gave us excuses as to why they could not accommodate us with another carrier. Very uncomfortable flight"

Pros: "overall the aircraft and schedule was ok"
Cons: "Our luggage did not arrive at our destination. It was an absolute nightmare to get it back!! I had to call the airline about 50 times, where most of the calls were not answered. I had to keep calling and following up. When the luggage did come they only delivered one of the 2 pieces. The calling marathon had to be resumed most of which went unanswered! We finally had to rely on the delivery company to provide alternate numbers where there was a possibility to get an answer. Absolute nightmare!!! Never never will I travel this airline."

Pros: "Both flights were on time. There was no difficulty with boarding, everything proceeded in an orderly manner with no untoward delays."
Cons: "Misleading information regarding carry-on baggage. Extra charge if I assigned myself a seat when I printed my boarding pass the night before the flight. Extra charge for every, little, thing. $1.99 for 3-4 ounces of Coke. 3-4 ounces of warm water with no ice. Seats that did not adjust. Minimal service from the flight attendants. On early morning flights (both of mine departed at 6 a.m.), when everyone was snoozing as well as they could, a flight attendant came on the VERY LOUD pa system with a commercial trying to get us to apply for the Frontier credit card. I will AVOID flying on Frontier in the future, and use it only as a last resort when I can't get a flight on ANY other airline (as was the case with this last-minute, necessary flight). It is the first time in over 30 years of flying that I had a BAD experience."

Cons: "Very uncomfortable cramped seats that do not recline. The price does not reflect that you have to pay for everything, checked bags, carryon bags, snacks, soda's. No entertainment even during a 4 hour flight."

Cons: "I was not allowed to e-check in... you don't participate in TSA Precheck and to add insult to everything else, when I showed up to the ticket counter to check in (because you don't allow e-check in) I was charge for my carry on bag. ... obviously the reason you don't allow e-check in. Who travels without a bag??? this is absolutely absurd. On the plane I was even charged for coffee and a glass of water... pathetic... When I asked why they parroted the obviously programmed response that management trained them to say "we're required to charge for that, it's our business model". On the way back I was again forced to check in at the ticket counter. I was asked if I wanted to check my bag or if I was going to carry on... I said carry on and the agent did not charge me. When I was boarding the plane the agent pulled me out of line and made me wait until an agent could come to the counter. They told me that the fact that the ticket counter agent didn't charge me was them not doing their job but that they were going to charge me $60 for the bag despite the fact that they "normal" fee is $45. I asked why I was being penalized because the agent didn't do their job????? Their response was "that's our business model". So let me get this straight, the model is mislead me into buying your ticket with what looks like a cheaper price, then don't let me e-check so that the ticket counter can "forget" to charge me the bag fee so that you can charge me more when I have no choice at the boarding gate..... then when I'm good and mad and trapped on your crappy jump seat (that doesn't recline) you charge me for water... You're airlines scumbag tricks and hidden fees are insulting and I hope people see this before they get suckered into buying from you.... You suck suck suck... and I'll NEVER use you again."

Cons: "Just a super cheapo airline that offered an "inexpensive" ticket that then they charge you for everything else, with no warning about the hidden fees. Like baggage: you can't take on more than one free, tiny check-in without paying at least $35, if not much more. Uncomfortable seats. The flight was 3 hours late when a neighbor flight to the same city (on Southwest) took off on time, and so they gave us this lame $10 voucher to appease us, and yet we couldn't use it anywhere, just pissing you off more. They wouldn't accept it at the airport or on the plane, so, what the heck?"

Pros: "Flight crew"
Cons: "While I used to like Frontier, my expectations have vastly lowered over the last few years. I'd say they met reasonable expectations except for the new seats, which I suspect are thinner and have allowed them to be crammed together even tighter for a few more rows. My major complaint is they've taken otherwise uncomfortable seating and established a new standard for discomfort."

Pros: "Getting OFF the plane"
Cons: "The new seats are flat out terrible. They're thin, poorly padded, and uncomfortable after only 15 minutes of sitting on them. I'm 6'-4", tall, but not a giant and my knees were against the seat in front of me. Legroom was nonexistent. When the stewardesses came through with food and beverages, it was $2 for a can of soda. So after paying an extra $30 to check one bag, and then paying ridiculous prices for a can of soda, and getting cramps after a 2-hour flight with no legroom, Frontier has moved to the bottom of my list for any future flights."

Pros: "Finally landing and getting off the plane"
Cons: "I paid for my bag, my carry on bag, my water, my coffee, and on top of it, the flight attendants on both planes there and back were incredibly rude to everyone. In addition, frontier has designed the worst tray table I have ever seen that can't even hold a drink, and is sharp enough to actually hurt someone should there ever be turbulence. The new seats don't go back. In short, this was the worst airline I've ever flown, and I'm not a high maintenance person."
