Pros: "plane was very nice and roomy, crew were friendly and good service"
Pros: "Not much crew stayed in back almost the whole 6 1/2 hr flight and seemed not to friendly"
Cons: "It would have been better if they had departed when they said they were going to after a delay. Flight was delayed first 1 hr then two more hours. The airline finally posted that it would depart a 4 PM and we didn't even start boarding until 5PM. Then they tried to rush us on so that everyone was standing on the HOT jetway for 10 min waiting to get on the plane. Plane didn't take off til 5:35 PM. Over all on this trip I had three flights that were delayed. I'll think twice before taking American Air again."

Couldn't get another flight that night to Austin so flew to Dallas, got in at midnight, had a to get a room which was not reimbursed. So sick of American Airlines and will not use them aga"
Pros: "The greatest part of the trip for me was the smooth landing."
Cons: "I wanted a voucher ride but they only needed a few volunteers."
Pros: "The Flight crew was courteous and took care of us despite a series of extremely unfortunate circumstances."
Cons: "Due to a computer malfunction we were stuck on the tarmac for some time, when it was decided to find a new gate to return to. /The tech crew eventually gave the all clear and upon returning to the tarmac, the same computer malfunction occurred, and again we had to return to the gate. This was all totaled 2.5 hours on the Tarmac. Finally, some 5 hours late we departed Miami in a different plane. Upon arrival in Phoenix, the captain wearily announced that there was no ground crew awaiting us, so we had to wait some time on the tarmac there to disembark. Never before had I heard a airline captain encourage the passengers to write a letter of complaint to his employer."
Pros: "Quick flight. Took longer boarding than air time!"
Pros: "Friendly staff and helpful"
Cons: "Did not fly out of Ontario, I was being led to fly out of LAX since there was a delay. Ended up flying out of John Wayne Airport."
Pros: "great"
Pros: "Boarding was quick, flight took off and landed close to the time it was supposed to."
Cons: "Seats could be more comfortable, first check d bag could be included instead."
Pros: "American did transfer us to another flight after several hours' delay."
Cons: "Lack of scheduled flight crew caused a 2 hour delay causing American to re-route us via Chicago in lieu of Phoenix. Still, arrived 2 hours later..."
Pros: "On this flight back to Arizona they arrayed mutt husband and I together, unlike on our way to Spokane. That was much better. We had more leg room this time."
Cons: "The seats are hard, fine for young people, but difficult for older people with arthritis and Auto immune diseases, such as fibromyalgia."
Pros: "Nice and clean and seats were comfy"
Cons: "No outlet to charge devices"
Pros: "On time. Nice plane."
Pros: "The plane was newer, drinks are available. Seat only reclines half an inch or so so get ready for that."
Cons: "Crew on aa is the worst bunch of entitled fools, almost as horrendous as united."
Cons: "Flight was overbooked"
Pros: "Nothing"
Cons: "They did not compromise when I couldn't go, I understand no refund but I cancelled a few days after,"
Cons: "Not a fan of baggage fees especially this high for only one checked. Next time Southwest Air, I guess."
Pros: "Nothing"
Cons: "Nothing was together, missed connection. Had to buy a hotel in Phoenix"
Cons: "delay, then no sandwiches available for purchase onboard during a 3-hr evening flight"
Pros: "The flight was very good. Boarding was good, shorter flight, smooth, landed and off we were."
Cons: "Seating still needs a little more padding for comfort. Delta airlines has a screen on every seat and you can see where you are and how far you have gone and so on. That would be nice. It was very difficult to hear what the pilot said when he spoke to say hello and whatever else he said. Entertainment? There wasn't any on this flight"
Pros: "Airline and crew looked after us and kept us informed. My app said the flight was delayed but the captain didn't seem to know this so we sat for half an hour or more after planned departure. Maybe he hoped to get an earlier slot. We were 30 mins late in the end."
Cons: "No food for purchase, just a drink and biscuit."
Cons: "There was no food offered. The stewardess was not happy to be at work."
Pros: "Friendliness of flight crew; entertainment choices."
Cons: "Food was poor for first class."
Pros: "Quiet. Overnight."
Cons: "no meal, no internet."
Pros: "Crew was fine even when we had to sit on the ground for 1 1/2 hours for a repair."
Cons: "American Airlines didn't honor my choice of seats."
Pros: "Flight was late arriving; then 45 minutes late leaving for PHX, creating concern about catching connection. However, once arrived in PHX, the connecting flight was in the same concourse, which was often not the case. So, could easily make the connecting flight. Also, the push by crew to "valet check" carry in luggage was too aggressive, especially since there was ample space to store luggage above the seats, then having to wait 10 minutes or more to retrieve luggage at entryway while being concerned about connecting flights was an example of a poor system for serving passengers when a flight is let."
Cons: "The wifi did not work and we were not offered any food, and the beverage choice was only water or coffee. Very old plane with broken seats."
Pros: "Everything!"
Cons: "Nothing!"
Cons: "bag got lost checking it at the gate in dtw, bag went to santa barbara, completely wrong airport. huge inconvenience"
Pros: "i liked that the flights were right on time."
Cons: "the plane was a bit cramped but I guess there isn't that much room in a plane to begin with."
Cons: "You need to add a not applicable choice to your list. I did not eat the snacks offered on the flight nor was there any entertainment that I could find."
Pros: "I like that the times American Airlines offered to get to my destination."
Cons: "The planes are not so clean and very old... These days it makes me more willing to pay extra to fly on a newer plane."
Pros: "The seats were very comfortable"
Cons: "Just wish the bag checked staff would've been more polite"
Pros: "Crew was nice including those helping with boarding."
Cons: "Difficult to recline chair. Limited snack options. Landing was a bit rough."
Pros: "The complementary snacks and drinks were good"
Cons: "Our flight attendant was late which caused us to be late so I had to change my flight and take a taxi go to LAX to catch a different flight and I was up for a total of 25 hours until I arrived at my final destination(my hotel) thanks a lot I will never use American Airline again if I have a choice of other airlines"
Cons: "They boarded group 1 all at once. I was group 2. They boarded all of us all at once. It was a cluster!. I haven't flew in 6 years. But when I did they boarded by so many rows. Not all at once . Boarding was horrible. It was like a cattle drive."
Pros: "I was asleep."
Cons: "The seats were very cramped."
Cons: "Crew were not friendly at all; I was sitting in the very last row and could hear them complaining about various things. The passenger next to me asked multiple questions and was flat out ignored each time. The seats were very cramped, the flight delayed; a friendlier crew could have made up for that"
Cons: "Delayed flight"
Pros: "The crew was so polite and helpful."
Cons: "Nothing could be improved for this short flight!"
Cons: "Stuck me with a middle seat even though I fly frequently On United. In fact they gave me a special recognition on an earlier flight which was ridiculous as well because it was just a piece of paper that I had to go up to the podium to collect"
Cons: "our flight was delayed in Chicago and our bags were not in Phoenix upon arrival"
Pros: "Nothing"
Cons: "My email is not linked to my phone, so I got no warning notices of two gate changes waiting for my connecting flight home. I waited at the original gate (C39) from arrival time (2:30 pm) til boarding time (5:40 pm). When I saw no change to my destination, I checked the United App to find that the gate had been changed C33). Rushing to C33 I found another flight boarding at that location with one United Representative who could not stop to answer questions. Seeing two unoccupied Representatives at the next gate (C32), I asked if they could help me with the confusion, they said I should check with gate C33 - which I told them that she was too busy with other passengers. I searched for a Departure Board and discovered that gate C33 was still the gate, but "aircraft maintenance" had delayed the flight until after 8:20. After having to check my carry-on because of lack of space in the overheads, my departure from the airport was further delayed another 30 minutes. Upon returning home and checking my email, I found notifications of two different gate changes (C33 & C44). Announcements should have been made at both gate C39 about the changing of the gate and at C33 explaining the problem. The captain's lame excuse about air conditioning and Phoenix's hot weather was lame to say the least."
Cons: "Delayed."
Pros: "From start to Finish from ticketing to baggage claim we received Premier Customer Service"
Cons: "I never flew to Phoenix from Washington. I was held over at DCA for the night so I lost a full day of my vacation! Had to fly to Chicago and then to Phoenix. Was a total pain!!!"
Pros: "I was happy to finally receive a drink one the flight started. A waterbottle at the seat and not other service would have been nice. Wifi was not working. The seats were small and cramped. My seat did not stay either up or down...it kept moving around and would not stay adjusted. However the crew was fantastic and our two female pilots were amazing. Captain Amy touched down in Phoenix was one of the smoothest I have ever experienced."
Cons: "This flight was horrible. I upgraded my seat and paid extra for a premium economy and it was still crowded. There was gum or candy stuck to the floor right were I was supposed to stash my carry on. I pointed it out to the flight attendant and his response was "so you can't put your bag there?" I asked him if he would ruin his bag and put it there and he said "well, you don't know me." What? I had to worry the whole flight about putting my foot on that gooey mess. What did I get for my extra money? Aggravation."
Cons: "There was no entertainment available on this flight. It's a short flight so I don't expect any, however, I continued on to Phoenix that day from Chicago and that is a long flight. I expected free entertainment on that flight, as it was afforded on the flight on the Phoenix to Chicago leg of my flights earlier in the week. The Chicago to Phoenix had entertainment offered but it there was a fee, which I didn't appreciate and did not take part in. I looked around me as much as possible and didn't see anyone else pay for entertainment. Having in flight movies and TV available for feee is a great incentive for flying with United. If these long flights in the future are pay for view, I will not be flying with you when there are alternative carriers who do provide free entertainment. Thank you."
Pros: "The crew was very friendly and courteous."
Cons: "First the plane arrived late so we could not board at our scheduled time. Then when the plane arrived they said we could not used that plane. Then we had to wait 3 hours before we could get another plane. The new plane was also on the other end of the airport. This was a challenge while traveling with my mother who requires assistance."
Cons: "Need to pay for everything... internet, tv, and snack. Long flight when you cant fork out more money for what was free with canadian airline"
Pros: "The food choices were good and the service was excellent, Always kind and responsive to my needs and attentive."
Cons: "Boarding could be done by letting people with window seats being seated first, then the middle seats next and finally aisle seats last! That way people would not have to get up from their seats after they have been sitting down to get back up to allow the people in the inner seat to get to their seats a pond boarding the plane after the people in the aisle seat are already sitting!"
Cons: "Reduced leg room because of seat construction"
Pros: "i was rebooked and am still on my way"
Cons: "i was delayed in ONT, making my flight an almost 24 hour trip from vONT to my destination. not fun had to reschedule car rental. luckily, they did not charge extra"
Pros: "The staff was very nice."
Cons: "I purchased two tickets and we weren't given seats next to each other."
Pros: "On time"
Cons: "Boarding takes too long"
Pros: "I liked how quick and easy the flight was; from boarding to exiting the plane in SFO."
Cons: "The size of the plane."
Pros: "Good service good snacks."
Pros: "Nothing."
Cons: "Staff."
Pros: "smooth ride in the air"
Cons: "-arrived in Phoenix 2 hours late -plane sat on the runway for an hour and a half before taking off. -my small carry suitcase had to be checked -bags took 45 min once we got to Phoenix"
Cons: "Very Rude while talking to me at the airport. Was not happy to assist me and other passengers even though it was the air-line mistake for cancelling the flight and delaying the flight. Will never fly with this airline ever again."
Pros: "Crew"
Cons: "Seating drinks/food pricing baggage handling"
Pros: "What did I like like that the pilot let us know what was going on on every moment and the stewardess was very friendly"
Cons: "Seats very uncomfortable last flight 30 minute flight took an hour if not more and not knowing what gate my next flight is until I get there"
Pros: "The crew was very helpful and polite"
Cons: "Anything but water was for extra. We weren't even offered a small snack for the price of the flight. My flight was changed three times and it was very cramped. They said there would be entertainment, but it cost as much as a movie ticket. They also managed to lose my bags for the third time in a row."
Cons: "The plane landed to San Francisco earlier than scheduled, but we could not get off the plane due to the gate not available. We were stuck on plane for about half an hour and I really worried about making my connection. I hope such arrangements are conducted more smoothly."
Pros: "The Flight attendants were nice."
Cons: "The airport was horrible. Hard to get to the C concourse. "train" is TOO SMALL. It barely fits 10 in each car. International transfer of bags was Horrible, and very far apart from where you get the bags. Poorly planned or not at all planned. We barely had time to make the flight with 1 1/2 hours to transfer and would have missed our flight if it wasn't for a trolley driver who took us from security to the gate. There is no power at the seats. The plane is old and seats were very uncomfortable. Yeah, this was the worst flight."
Pros: "Zero leg room! That actually was surprising as most other airlines have a lot more legroom. In flight entertainment was also lacking. Doesn't make sense to pay $7.99 for a 2.5hr flight. A lot of other airlines offer some sort of complimentary in flight entertainment. Also the luggage didn't start coming out for at least 30 mins of waiting at baggage claim. Not the worst experience I've had flying but far from being a good experience. It probably isn't worth flying united unless it's 1st class. But even they had to wait 30+mins for luggage!"
Pros: "Nothing"
Cons: "Flight was delayed two hours, lack of communication regarding delays even after airplane arrived, seats were uncomfortable and lacked room."
Cons: "The only thing I didn't like was that my flight was delayed. But hey, it happens. Over all it was great"
Pros: "I felt comfortable. Staff was great."
Cons: "The cracker and cheese box. The snack wasn't worth the money."
Pros: "Flight Attendants were nice."
Cons: "The flight was expensive and they wouldn't let us or anyone place carry ons in the over head bin. It was an expensive ticket and didn't include checked bags ($25 more). Carry-ons wound up being "stowed". It would have been nice to know before I bought the tickets that I needed a smaller carry on."
Pros: "Boarding started early and went very quickly. Seats were new and a leather type material , which is an improvement from old fabric seats. Nice headrests you could bend to support your head. Loved the new United app I downloaded for free which allowed me to watch movies and tv shows on my phone. We arrived at our destination 30 minutes early, which was a plus. Staff was friendly and helpful."
Cons: "They overbooked my flight and almost didn't let me on the plane even though I bought my ticket months ago! The only reason I got on is because some people didn't show up."
Pros: "Nothing."
Cons: "So many problems with my fly. Bad service. Never fly with united air lines. No recommended to any body"
Cons: "I paid good money to be back by 6am however I was delayed and had flights cancelled which made me get home 10 hours later than I should have. This was an overnight flight, so all the places to buy food were closed- United didn't offer snacks or blankets or really anything for the troubles. There were kids also stranded."
Pros: "Seemed to be a newer plane, and there was in-seat entertainment at each seat. Mine didn't work, though."
Cons: "United has to have the smallest seats of any carrier. There couldn't have been more than three inches between my seat and the seat in front of me. The guy in the middle seat wasn't a large guy, yet he poured over into my space. It's insanely small."
Pros: "Nothing"
Cons: "I was angry that I had to fly to Houston before heading to Phoenix which made my arrival in AZ much later than I had planned. My flight had been rescheduled since I missed my flight the night before because the first flight had been delayed. So the new flight was a longer trip because of the extra layover. The overall flight was a mess."
Pros: "Price was great and flight crew was nice."
Cons: "Rows 20 to the back of the plane didn't get a beverage. Slow moving attendant. I was thirsty."
Cons: "They over booked my flight, so I would have missed it had someone not gave up their seat for me. This was extremely disappointing begin that I had booked months in advance. I even picked my seats!"
Pros: "On time."
Pros: "The only thing I have to say that is positive is that it was relatively easy to change my flight date and time in the United app once my original flight had been cancelled. The app was the only thing that helped me understand what was going on during the constant time and gait changes throughout the day."
Cons: "This airline is terrible. First we were told that the flight would be delayed 1 hour and 40 minutes. We were supposed to leave at 2139 from IAH to PHX. They changed the departure to 2309 due to "mechanical failure" of one of the aircrafts. We were told a plane was coming and that we were just waiting for another flight to Albuquerque that was delayed before us to leave the gait. Long after that first delayed flight left passengers for PHX were delayed 3 more times which ended in the final tenative departure time being 0145. We were told at 0115 to sit tight and wait because the plane was now here but the crew was still in route. Shortly after this promise, the crew showed up and everything seemed to be ready for us to board. Another 30 minutes went by and they announced that the flight was cancelled. United airlines had used up over 4 hours of changing gaits and times only to end up cancelling the entire flight. They did not offer any explanation for this nor were they the least sympathetic to the travelers who have all paid to be on that flight. The customer service was disgraceful and did not offer any type of help on reimbursement, hotel, cabs, or compensation for this."
Pros: "I love United. They're now my go to airline. I love the pet friendliness as well as every employee through United I met today from the bdl check in crew , to especially the flight crew on flight558 iAd to phx who I believe was from Houston and their Texas roots truly shined. Every crew member was Sooo attentive professional Cleanly pleasant and always smiling and happy to come around. Other crews could learn from this crew please take notice !!! I have never been so impressed (and I am a frequent flyer )"
Cons: "Flight tracker wouldn't work on screen or on phone disappointing"
Cons: "Food selection awful"
Pros: "I had an empty seat next to me and was able to have some more comfort on the 5 hour flight"
Cons: "The flight was delayed twice, very frustrating as we were already arriving at midnight."
Pros: "Was impressed w the new plane"
Cons: "Overhead storage a little small"

Its frontier so I don’t have high expectations

Delayed without updates. Missed a day of work

I arrived an hour before my flight and I was unable to get a boarding pass . They were only able to reschedule me a minimum of 2 days later. Totally unacceptable. Tries getting a voucher or a credit and they were going to charge me more fees then what I paid for. So unacceptable

Cons: "Getting off the plane ( We were stuck on the plane for at least 1 hour and twenty min. )"
Pros: "Seat was very uncomfortable"
Cons: "No entertainment"
Pros: "Clean plane, great customer service."
Cons: "You have to pay for a reclining seat, only the first theee rows have them. You have to pay for even soda drinks. Ok for shorter commutes, but a 4+ hour flight is miserable."
Pros: "The attendance"
Cons: "Tight seats"
Pros: "That I made it there in one piece."
Cons: "Not worth saving a couple dollars. Front tier airlines does not allow you to pick your seats before hand nor does it allow you to select baggage and the app, it is recessed for whatever reason. The seats are extremely tiny the tree table is so small you can barely fit an English muffin on it. There is no entertainment whatsoever, there is no Internet on the plane, and if you want anything to eat or drink besides water you will be paying for it. I’m sorry to say but flying on frontier was more like a punishment for me. I always fly American and wanted to save a few dollars what a mistake! With American most the planes that I have flown in have free movie entertainment and everybody seat the seats are comfortable And recline. And the snacks are free along with the soda. Please think twice before flying frontier."
Pros: "Do people write here for frontier?"
Cons: "Sat on the tarmac for over 3 hours. A fight broke loose and we had to return to the terminal and then back to the tarmac for more sitting. The crew finally figured out how uncomfortable and frustrated people were getting 2.5 hours to sitting with no air on the tarmac. They relieved their customers suffering then with complimentary water! Now that’s service. Frontier is one of the most base airlines out there. I’m entirely frustrated that they are one of the only airlines that service our podunk airport."
Pros: "The plane safely landed."
Cons: "Customer service, overall lack of competence and an inability to communicate laterally with other airlines who were using their gates. Seats are also incredibly uncomfortable."
Pros: "I called Customer Service as I needed to request a wheelchair to and from gate. The Customer Service Agent was pleasant and accommodating. I while I do not like paying for my luggage to accompany on the flight, I might try you again."
Pros: "Crew Is okay."
Cons: "As expected, anything extra (carry-on, water, food, etc) will be charged extra. Seats are small and do not recline"
Cons: "My seat was not worth an extra $50. Sat next to a lady with a stinky dog in her lap that was probably a little too big for lap."
Pros: "The Frontier staff was very welcoming in boarding passengers on this flight & that the view of the flight was awesome coming into Phoenix."
Pros: "Before our trip, I read some mixed reviews, but honestly the experience was what I expected. The crew was really friendly and attentive, our flight took off and landed on time, so that was great."
Cons: "The seats were only so comfortable, and don't recline, no in-flight wi-fi, and everything needed to be purchased as extra. This was what I was expecting though, so I came prepared with my kindle and snacks purchased from the airport."
Pros: "Boarding was swift"
Cons: "I checked to see how much it cost to pay for my 2 checked bags online, it was 25.00 each. This was on a Sunday. Come Monday I went to pay for my two bags online but now it cost 35.00 per bag, WOW!!!"
Pros: "Not much"
Cons: "This used to be our favorite airline about 6-7 years ago. Now it's just a last minute ticket availability decision for only very short trips!! So uncomfortable, rude attendants and so many fees!!!"
Pros: "The baggage claim girl in Atlanta was Wonderful she was very pleasant to me and my boyfriend and expressed a genuine concern about my unfortunate circumstance. Mariah (Frontire baggage claim girl) did everything she could to make sure I got my Bag back and called as soon as it arrived Thanks Mariah !!!!"
Cons: "They lost my bags I was flying to Atlanta from Phoenix and my bag ended up in St Louis ... i would assume that if your going to make me pay for my checked bag it would atleast make it to the correct destination. The crew wasn't as pleasant and friendly as I'd like them to be but did there jobs (I guess) then we had to sit and wait for a gate .... the only reason why a gate finally opened up was because people started asking for snacks. Overall there was nothing special about this flight I was upset that I didn't have my luggage from the beggening of my trip but the day before I left my bag was recovered . The ticket was inexpensive but I'm not sure if it was worth the hasstle Then I had to pay for my bags coming back as well. Suggestion maybe have a 50% voucher ad a courtesy from sending a bag to the wrong destination."
Cons: "They say low fares done right but my "cheap" flight turned out to cost me over double what it should have with their extra cost for everything! And I mean for EVERYTHING. Will never fly frontier again!"
Pros: "If you have ever flown Ryan air ,this appears to be the American version."
Pros: "I liked the bundle package of a carry on, a checked bag and stretch seating. A fair price for the extras and the stretch seating is definitely a must!"
Cons: "I wasn't really impressed by the general lack of kindness from the flight attendants. Seemed like they hated their jobs and didn't want to be doing it. Didn't really want to ask for anything because I felt like I was inconveniencing them."
Pros: "Nothing"
Cons: "Arriving to the airport at 5am and reviewing my experience at 11am, still waiting to board the flight that has been delayed over and over."
Pros: "Likely the most uncomfortable plane I've ever been on. Seats feature zero padding, the inability to recline, and a tray table the size of a DVD case. I'm 5' 9" 148 pounds, young and very healthy. I left the plane with a twisted up neck like I've never had before. I landed safely so I MUST be thankful for that, but if I was booking I would want to know this information. Since I'm the wiser now I will not book with Frontier again. Also it was an extra $90 for my CARRY ON round trip. It notified me it would be extra when I booked online but didn't specify how much. What a surprise. I spent more on the fees for the bag than I spent on the bag itself (and most of the contents for that matter)."
Pros: "friendly crew members"
Cons: "I was given a boarding pass that had the wrong boarding gate.I was boarding the flight from sky harbor Phoenix to AtlantaI. I almost missed my flight and nobody told the passengers the gates had been changed. I did not like that and felt disrespected. Yet I had paid for the flight."
Pros: "Paid for more room. It was enough. Glad I paid for it. The price kept going up as I was shopping seats (over the course of 20 minutes) the first time this was after the site crashed. Lame."
Cons: "Seat assignment pricing slowly tickin up as I check in seemed predatory. Baggage policy confused most people and made boarding slow. Rude worker. Everything costs $$$. Not worth the headache for the few bucks saved (I saved $20 at the end of day to not take Delta.)"
Pros: "Nothing Good To Say At all"
Cons: "My flight was cancelled twice and then once i was able to get a flight to phoenix from Cleveland it was for 3 days after my original date of departure and then they expect me to pay for a different airline if i wanted to leave on my scheduled date i think this airline is so unorganized it makes no sense and ill never fly with them again"
Pros: "Short flight. - But loved the price - very cost effective."
Cons: "My stay was short so I didn't need to check a carry-on or bag. Had I needed that service I would NOT have chosen Frontier - I seriously object to having to pay extra for an item that is not an "extra" - who travels without some type of luggage?? Just charge the cost up front and be transparent - it is difficult to determine exactly what your flight is going to cost you - which is exactly why I don't normally fly Frontier!"
Cons: "Will not use frontier again, I had no idea they didn't cover even a carry on. Also, couldn't lay my head down on the tray in front of me on the plane, it was way too short and way too low."
Cons: "A completely unprofessional,disorganized and disappointing experience. I will be sure to steer everyone away from this airline in the future"
Pros: "Boarding seemed smoother than American. Seats are pretty comfortable."
Cons: "Extra charges for carry on is not great, but it does make you think about what you pack!"
Cons: "Had to pay for drinks and couldn't recline the seat even a little. Also, microscopic tray tables. Having to pay to choose your seat and get a lemonade on a flight is not my idea of comfort or convenience."
Pros: "The seats were surprisingly comfertable! And I really enjoyed having more personal space in front of me! No other airline have seating like Frontier! I flew United in to Colorado and it really felt like sardines with Frontier I didn't and both flights where full!"
Cons: "I didn't like the surprise 40$ fee to bring carry on. I don't remember seeing that when I bought my ticket. I don't mind paying for my luggage. But would've been nice to be able to add that to my flight bill rather then having to pay the fee in order to get my flight ticket."
Pros: "Flight attendants being apologetic"
Cons: "Boarding agent was very rude and told me I could not board because of dog. Even the other passengers were appalled by his behavior and complained. on board flight attendants had to apologize for his behavior as well. He made me cry and wouldn't let me board. It was the worst flight experience I've ever had."
Cons: "Tried to cancel this flight using the flight insurance I was up sold during checkout. Turns out that the flight insurance was only available for international flights? When I ask the agent why it was the recommended during purchase, she said I should have read the full terms and conditions during checkout. To me, this was a true scam. She told me that I could appeal the conditions of the travel insurance, but I would have to present a death certificate of the friend's baby that had just passed - the reason the baby shower was cancelled, and the reason this trip was cancelled. It was appalling. I tried calling Frontier directly, but their reservation desk was closed due to their system being down. HOURS I tried to call, and could not get a rep. I ended up not able to cancel the flight or even speak w a Frontier rep before my flight departed. In all, I was given 6 different numbers or lines to call to sort through this situation. All I did was waste hours of my time. This was a terrible situation where I feel like I was the victim of a scam."
Pros: "I made it to my destination."
Cons: "Fees to have a seat on a plane you already purchased a ticket for. Carry on fees are ridiculous! I will never fly Frontier again nor will I recommend it to anyone... Ever!"
Pros: "I didn't like anything about traveling with Frontier."
Cons: "Upcharge for Seats, Upcharge for Checked Bags, Upcharge for Carry Ons, Upcharge for Water. They charge you for water. That seems illegal. The flight was delayed, the gate was changed. We had to change gates which means we had to go through security twice. The staff blamed everyone and everything else (even the passengers) for all the issues and took ZERO responsibility for anything. I can't believe they are still in business with this level of customer service. The flight attendants were ghetto too. Making light of a bad situation by saying the worst things possible. Total embarasment transfer. I'll never fly Frontier again and will think twice about booking travel with Kayak."
Pros: "Co-pilot who had to explain to passengers why so many flaws occurred in this flight, she tried to be humorous."
Cons: "Flight 1884 out of SFO was doomed from the beginning starting with a notice (thanks Kayak) via email that the flight would be 1 hour late. Then, the Departure board at the airport totally dropped the flight, Then (again thru Kayak) I read that the flight would NOT board in terminal 1, Gate 21, Domestic terminal, but ar gate A3 in the International terminal. We all had to exit domestic and go to international and again through TSA. Then the flight departed another 30 minutes late finally over 2 hours LATE! Upon arrival at Phoenix the plane taxied too far away from the exit ramp-another 40 minutes before we could depart. It was an awful flight experience. Did they offer a free soda or anything for inconvenience we experienced-NOT A THING!"
Pros: "At least this flight was only 15 min late!!"
Cons: "Told to arrive early only to show up and realize he bag check counter is unattended. A sign states it will open 2 hours prior to boarding. Staff shows up late then has to log on to computers and get ready. Once we check bags, lines are so long at security we are diverted to different gates. Worst airline I have ever used."
Pros: "My flight eas very friendly/ peaceful also a great experience for over 3 hrs"
Cons: "N$"
Pros: "The flights went fine, and were mostly on-time, just a little delay leaving Chicago because the incoming flight had to wait for a gate to open up"
Cons: "Frontier's customer service line is horrible, with no clear option to reach a person to ask questions of without hunting through every option. Also, they charged me to pick a seat, ANY seat, so what the hell am I paying for when I pay for a flight?! I also had to put my backpack under my seat, even though it was stated numerous times on their website that it would be too big, and I had to pay $40 to make it a carry-on, when there was no room in the overhead bins. Their customer service line AND website stated I could be charged up to DOUBLE that ($80) if I had to pay for it at the gate. I looked it up, and I would have payed less on at least two other carriers because of the extra charges. This is information that should CLEARLY be stated when listing the costs of a flight, not "covered" under "additional costs may apply" or some such legalese"
Cons: "I bought a plane ticket and then had to pay for a seat on top of that, as well as exorbitant charges for bags, and we ended up paying far more than even the plane ticket for all the extra charges. If I buy a plane ticket, that price is what I am expecting to pay. I understand a few charges here and there, but more than double what I expected to pay is completely crooked and terrible business. The plane ride was bare bones, uncomfortable seats, and average service. We will never be flying Frontier again."
Pros: "The flight was cheap and affordable"
Cons: "paying for carryon luggage and the price being 45. paying for snacks and drinks thats over priced and should be free like the other airlines. seats no longer recline and you have to pay for a seat if you pick one. by the time you pay for all of it the flight costs more or about the same as thr airlines."
Pros: "I'm handicapped and the service I was given was excellent. From the moment I walked in the door at DIA I was given superb service. It made the trip so easy and pleasant. The flight attendants were also helpful when I needed a little water to some medication."
Cons: "Charging for carry on baggage is ridiculous. I was warned ahead of time so I carried a oversized purse that would accommodate a book and my ipas mini. But charging for non alcoholic beverages is highway robbery! And the food offerings were nothing but junk food. No wonder you are rated last in the airline industry for customer service."
Pros: "Not much. Will not fly this airline again."
Cons: "Extra charges for everything. Even water and coffee weren't free. Seat charge, what is that ? Overheard a fellow passenger say he felt as though we were treated like cattle."
Pros: "Flight was short"
Cons: "I was not informed that I would be forced to pay for a carry-on, which was more expensive than checking my bag. I checked it, which then forced me to have an additional 30 minute wait at baggage claim. Horrible experience especially due to the splitting headache from the child who was screaming louder than I ever thought humanly possible (that obviously wasn't the airline's fault though)."
Pros: "Flight was on time, boarding was quick."
Cons: "They charged to pick seating, for carry-ons, and for beverages on the flight. The money I "saved" compared to other airlines, I ended up probably spending more due to the additional charges."
Pros: "This is a good option if the price differential va other airlines is significant enough. However you must consider all the add on costs in that value calculation. Charges to reserve seat and check in on line, charge for carry on, charge for all drinks etc"
Cons: "Seating is beyond uncomfortable."
Cons: "The person at the gate informed me that I would have to pay for my bag. The same bag I had just brought from Portland on the same plane. She was rude ."
Pros: "Nothing"
Cons: "Plane cancelled, no help from frontier customer service, will never fly on this airline again"
Pros: "Boarding was quick and easy"
Cons: "everything is an up charge, from carry-on bags to soda and snacks. if you want any and I mean any extra legroom expect to pay 17-25 dollars extra as well."
