Pros: "Nothing, was scheduled to depart at 10AM, is 3 PM and no info whatsoever."
Cons: "Taking ownership of the issue by the staff at the counter."

Pros: "Good services"

Cons: "Leg room and seats are uncomfortable"

Pros: "Quick Flight and nice crew."
Cons: "The crew wasn't the problem at all. Some of the passengers were just being obnoxious and sitting next to their friends not what their seat numbers were. The BIGGEST problem are the packed planes with no social distance between passengers which is a HUGE concern for me."

Pros: "The overall flight was good!"
Cons: "Maybe make sure that communication between connecting flights are quick and efficient."

Pros: "Movie selection and comfort of seats"
Cons: "They somehow “lost” luggage for half the hee passengers, and we had to wait for 2 hours by the carousel for them to “find” it. Totally unacceptable."

Cons: "A tv on plane"

Pros: "Nothing"
Cons: "Boarding process"

Pros: "Everything was great"
Cons: "Nothing"

Cons: "Landing"

Cons: "Didn't get snack. WiFi entertainment wasn't working."

Cons: "Flight was cancelled, some staff I dealt with to rebook had some attitude issues, others where fine. Overall not very transparent throughout the process. Definitely could've been much more helpful."

Cons: "I had little leg room"

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: "ABSOLUTELY NOTHING!"
Cons: "At 12:40 p.m. we boarded American Airlines flight 1350 in ATL, just to SIT on plane for 1 1/2 hours (half the time with NO AIR). Computer problems. Had to get off plane, then had to wait in 3 lines. Agents were so UNPROFESSIONAL! Kept saying flight would go... DID NOT go until another plane came in at 9:00 PM! We, needless to say missed our connecting flight to SYDNEY and had to wait til next day and fly to SAN FRANCISCO, then to MELBOURNE, then on to Christchurch. We MISSED out on TWO DAYS of our short trip! which included missed reservations!!"

Pros: "We took off on time and landed about 45 minutes early. That was great"
Cons: "My bags were lost and didn't arrive in New York with. They were not delivered until 1am that night."

Pros: "How fast they had us in the air (5 min early)."
Cons: "In their rush to leave, they didn't communicate with the on board crew about overhead bins and I was forced to check a priceless item that I purposely wanted with me in the cabin. The overheads were empty above my own seat. I wasn't allowed to go back and reclaim my bag because they had already taken it. And they were completely indifferent to my situation, which isn't surprising given they didn't understand the value of my item. Thus, I had a full blown panic attack for my entire 2 hour flight, my medicine being one of the items also in my now checked bag. It was too late, my bag was taken and thrown under the plane by the time it struck. And the flight attendants also had on perfume that brought on a tension headache due to my sensitivity to scents. Considering they work in a recycled air tube, this seems like a vast oversight on their part and should consider that not everyone can handle even the faintest of perfumes. It may not seem like a big deal to them, because mental illness is still seen as a made up thing, but it was enough of a trigger that I will not fly American Airlines again."

Pros: "the staff was great from check in at the airport until I landed"
Cons: "I wish the snacks were heathy like dried fruit and nuts"

Pros: "The airplane was modern, clean and comfortable and the flight was on time"
Cons: "Everything was good"

Cons: "The flight was late"

Pros: "VEry good Cabin crew and the plane was reasonable new"

Pros: "Wasn't completely full."
Cons: "Nothing"

Cons: "An extremely rude woman told me there was no space to place my bag in the overhead compartment and forced me to step aside and check my backpack. I didn't have a purse or any other item, just a backpack. I told them I had medication and they told me to just put it in my pockets. So I stashed my medicine in my pockets and had no room for my personal items or valuables. I had a hiking backpack with a water bottle in the side, and since they forced me to check the bag, my water bottle flew out of the pocket while it was being loaded onto the plane. Fortunately they at least tracked me down and brought my stainless steel water bottle to my seat. However, it wouldn't fit in the pocket in front of me and I had no other bag to store it in so I had to hold it and a few other belongings in my lap for the entire flight. I also had some other fragile items in my backpack that may or may not be okay. Also, when I boarded the plane, there was still space...there was no need to be so rude and force me to check a bag being used not only as my suitcase but as my purse as well. I'm so displeased with American, their staff, and their overall disorganization. How ridiculous."

Pros: "The actual crew on the plane were great"
Cons: "On my trip to Atlanta from new York the gate staff were horrible. Nasty attitudes and forced me to check in a bag that is made and approved by airlines to be considered a carry-on making me miss my 6 am flight to then book me on a 930am flight that was delayed for about an hour. I've never experienced this with any other airline before. Very disappointed"

Pros: "Seats had good leg room, and the current movies were free (unlike on the United flight I took a short while ago). Boarding was quick."

Pros: "In General, as a premium passenger, I usually enjoy the premium cabin experience; however, it was lacking this time."
Cons: "In first class, three/four of us requested headphones/headsets; the flight attendant informed us that there were no headphones/headsets; thus, we could not watch any programming In first class, there were two meal options, but one was almost immediately depleted before the flight attendant arrived at my row."

Pros: "Nothing"
Cons: "Flight attendant called cops on passenger sitting next to me to be escorted off the plane for no reason!"

Pros: "The gate agents did a good job of making sure the boarding process was organized, despite confusion with two Chicago-bound flights departing from the same gate in a short window. Delay was communicated far enough in advance that I didn't travel to the airport until it was necessary."
Cons: "The flight was delayed 3 hours due to the incoming aircraft, but nobody at the gate or onboard offered any explanation or even acknowledged the delay. The aircraft did not handle turbulence well at all... one of roughest flights in recent memory despite avoiding weather. Wifi had weak signal (on a 70-person jet!) and the streaming entertainment did not work the entire time... it either did not load or I got an error message."

Pros: "The flight staff had an amazing energy about them especially for 7am. They didn't do anything above or beyond but they extremely pleasant, energetic, and courteous. The pilots also pulled off the one of the smoothest landings ever."

Pros: "Quick flight, great service"
Cons: "Was not accommodated for a missed flight"

Pros: "Flights were on time if not early-Excellent"
Cons: "E tickets or even itinerary should have terminals listed on E ticket LGA-got off at Am terminal B to find out I was leaving from C Had to take shuttle to C. Return to NY same issue-had to ask what terminal I was at To notify my driver once I was off the plane."

Pros: "The crew was friendly and helpful. Very pleasant"
Cons: "There was no Chardonnay available."

Cons: "The obese person was NOT supposed to sit next to me (in my row) he had the seat in front of me. He saw that there were 2 men in his row, he switched to sit in the middle seat 1 row behind. However, i paid extra to move up and i ended up being squashed, sitting very uncomfortably. The man took up half my seat. The flight attendants knew of the messed up seating but did not correct it. Overall disappointed, they should make sure everyone sat in the right place."

Pros: "Pilot announced a change in time."
Cons: "Paying for my plane ticket broke college kid..."

Pros: "Really great flight"
Cons: "The wait"

Pros: "I like that the crew was professional and courteous."
Cons: "That I was there and hour before my flight and my seat was given up. I didn't like that people are allowed to retract all the way making my flight uncomfortable."

Pros: "I have been traveling several times with this airline and think they are good overall."
Cons: "Reclining chair sometime is not working."

Cons: "Flight was late arriving to Atl flight was late arriving to Chicago made me miss my connection to FNT American rebooked (after they told me they hold plane I ran through 5 concourses to get there n American still left me and several other passengers) through United late flight to FNT a 4 hr lay-over turned into 6hrs 2 plane changes cause of mechanical issues n had to run 2 concourses over still was late leaving and arriving to FNT...."

Pros: "Crew was very professional and courteous. Our plane landed early which is a plus"
Cons: "I didn't like the fact some of the seats appeared to be dirty , I sat on a book."

Pros: "Everything was perfect from the boring to me getting off the plane"
Cons: "nothing wrong"

Pros: "food"
Cons: "My flight was overbooked. I almost didn't make it home."

Pros: "The passengers"
Cons: "A/c was broken"

Pros: "Well.....it was canceled so I had to go to charlotte after to London and at the end at Rome and every one of them had delay's"

Pros: "Respesv your promise for the bording time"
Cons: "When the crew bothering me"

Pros: "Everything was great"
Cons: "I like everything"

Cons: "They overbooked the plane and the customers used the overhead compartments for very small items; such as bags and briefcases which made the overhead fill quickly."

Cons: ". The plane was clearly a very old model - very cramped."

Pros: "We didn't crash."
Cons: "The crew was just downright rude. Condescending rude and full of tude. Also they are all 100 years old and one lady was so fat she could barely fit in the aisle. Come on AA...really you can't do better than this?? Seats were uncomfortable as can be and food weas slightly worse than average airplane food. funny thing is I always fly delta and delta partners but this time I thought I would go the cheaper route. Never again will I fly American anything anywhere. Very disappointed. There is nothing positive to say about anything except the fact that we didn't crash. We were also delayed 2 hours and sitting on the Tarmac. Horrid experience."

Pros: "Very little"
Cons: "Flight was delayed because of weather, which is understandable. The way your staff handled this in both Atlanta and Philly was totally unacceptable. No one knew what to do. I missed my connecting flight to Rome, Italy. I got a good deal on the tickets but in the future I will stick with Delta."

"Good"

"Flight was late at boarding and, once it took off and landed, crew team was not at the gate on time. We had to wait again over 20 minutes to park the airplane at the gate."

"Things were cool. No entertainment or water"

"Worst flight ever ! 2 hour delay for nothing couldn’t even buy a water. Ridiculous"

"I liked nothing flying from ATL to Denver , flight was delayed 4 hrs , we were told to move from one terminal across the airport , then was told to move back to the same spot later when we were told the flight will be leaving at 12:12 vs 1:46 am which means they moved us three times . When we got back to the first spot which was d1 from e1 we were then told we will be departing at 1:46 😂. I had my wife and daughter , we were never offered anything at all , when we used the vending machines in the airport nothing worked no stores open at all. When we finally got told to board we were placed in the tunnel for over 20 min , then where It got real bad was in the plane , take note we were all tired hungry and wanted something to drink . We then board the plane , we sit down and I asked the Stewart if I could have some water he told me when we are in the air , I told him thank you and tried to get comfortable as we have Been sitting in an un air-conditioned airport In The section we were in . As I am sitting there the same person I asked gave multiple bottles of water to certain individuals , I was flabbergasted at that point but wait gets even better . I am exhausted at this point as I have walked miles in this airport with my wife and daughter . We get in the air and he gives me a small half cup of water , lol what a kind gesture . The cabin lights dim besides where the stewardesses are sitting , about 15 min goes by waiting for the plane to get dark so I can fall asleep but remember hungry and tired . I watch two of them start cooking ramen noodles , cup of noodles , chicken and sweet potatoes, make tea and drink multiple bottles of water mind you hungry , tired . I then watch then have a full blown conversation and eat right directly infront of me , no social distancing at all , concerned at this point hungry , tired , thirsty , gets better . Two more come up they start to eat no social distancing 4 people full blown conversation , lack of other people's space , inconsiderate, we ask them to quiet down alittle so they continue with no mind being very rude and unthoughtful of how much everyone went throught from the nasty floor, unconditioned area of the airport, to the vending machines that don't work, the flight delay moving my family three times , watching people eat with no consideration of others , no way to sleep cause 4 frontier stewardesses wanted to eat , discuss there issues, and carry on like we don't exist with the lights on the entire flight in the front of the plane , my entire Tuesday was wasted , now today not doing so well as you try and give us 50$ voucher ."

Pros: "Nothing i thought it would be the price but that is not worth the headache to this trip. You pay for what you get."
Cons: "Not paying for carryons, having water to drink. Not so many changes and charges. I will never fly with this airline again"

Pros: "Smooth flight great pilot. Easy boarding"
Cons: "Not much"

Pros: "Very efficient"
Cons: "All good"

Pros: "No"
Cons: "That they at least provide water or snacks"

Pros: "Uncomfortable seats"
Cons: "Left and landed on time. After landing, an open gate to taxi to would have been nice. I missed my train."

Cons: "Everything"

Cons: "Flight was delayed 5 hours with no explanation"

Pros: "Execution of the boarding/ exiting process"
Cons: "A little more space"

Cons: "Did not fly the had to change the flight frontier website does not work with safari. I change the flight an hour after I mad the flight and they said because I did not use google chrome that the change were not made they waned me to pay 402 to change a flight that I booked for 194. I could have bought two more tickets for 284. The told them that is what I need to do. By the revues I saw on line the did the same thing to at least 10 other people. Frontier said that a customer only has 4 hour to make a change to a flight. I talk to sever travel agents and was told we have 24 hours."

Pros: "Arrived in one piece"
Cons: "Departure was approximately 40 minutes late due to the plane arriving late. If you fly Frontier it’s you know... business as usual. I fly a lot and every other time with this airline has the same issue. Upon arrival we waited approximately 32 minutes until we were able to deplane. Crew unapologetically explains that since plane is going to maintenance we are at a shorter gate hence the delay - it is what it is. We are getting off some makeshift jetway. What?! At this point the passengers are ready to walk down the tarmac. I’m just glad it’s over."

Cons: "The Frontier workers at the Atlanta airport were highly unprofessional. My flight was delayed but there was no announcement made until everyone was already questioning why we weren't boarding. The worker told me 3 different times for our new flight time and when I asked him why there was confusion he told me to check the website because I could look up the time just like he could. So much confusion. I saw people miss their flight before mine because boarding wasn't announced."

Pros: "Boarding the plane was simple and like most other airlines"
Cons: "First and hopefully last time flying Frontier. Carry-on baggage charge of $60 per person at the gate and only $35 online...added bag online to avoid additional fee. Boarding was fine, but had to wait 45 minutes past take-off time for mechanic to sign off on all maintenance items for plane. All the while, the crew stood around and didn't make anyone aware of anything, almost like it was something that happens to them all the time. Very unprofessional and clearly not focused on the actual people on the plane. The flight attendants were chatting with each other like they were off work and NOT attending to anyone. Very poor crew."

Pros: "The seat terrible no movie no water over 4 hrs terrible 35 dollies carry on bag at the end is more expensive than any good airlines Was on time departure but that is what we expect flight attendant didn't even want to answer if I have to pay 2.99 per Soda ... the price is in fmenù in front of you... and quote"
Cons: "Every thing is bad"

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."

Pros: "We never took the flight as we waited in the airport 2 hours from boarding scheduled for 8:00 p.m., as suggested, until after 2:00 in the morning, when we heard not from Frontier, but another passenger, that the flight was canceled. No flight was available until Christmas Eve, six days from the current flight, and so we spent considerably more money for all three of us to get home with another airline. I, nor any of the three of us, nor anyone we've told our story to, wishes to ever fly Frontier again. It is an event that will certainly impact our decision to fly Frontier again, without a doubt."
Cons: "No flight No announcement right away about the cancellations, nor the delays Multiple reasons for the delays No definitive answers about what was going on Multiple additional expenses on our end that we hadn't planned on. Vouchers, but weren't enough to completely compensate for hotels"

Pros: "The price was good, but still not worth the money. Landings and takeoffs very smooth."
Cons: "Denver to Atlanta one of two bags lost. Delayed our trip to Asheville by several hours and arrived in the dark, much to our chagrin. The bag was 'driven' directly to the house the next day. On the return, the bags were nearly an hour late before appearing. We were over charged for bag fees. Computer did not show the checked bag purchase at booking, so were charged full 'at the gate' price. Seats are uncomfortable and do not recline. Rows too close together. Every seat filled, making the flight noisy, crowded and uncomfortable. The flight was definitely NOT worth the savings."

Pros: "Leaving and landing on time."
Cons: "Waiting forever while only two people did check in. The fact the carry on's cost more than checked bags or that they both cost so much."

Pros: "The only thing I liked about Frontier was getting off of their plane."
Cons: "Where to start? The 5 hour delay was horrible. The customer service was non existent. I've never see such rude people. We asked for their names to report them and they refused to give us their names. They lost half of our luggage. All of this was just the outbound flight. On our return flight we walked up to the gate right as they were closing the door. Thy refused to let us get on but offered to rebook us another flight 2 days later. Asked the speak to a manager and it turns out she was a manager....lol. We had to buy another flight on Southwest Airlines to the tune of $325. All of this and never once did anyone apologize or try to do anything to make it better. There is a reason Frontier is cheap. Do yourself a favor and stay as far away from them as you can."

Pros: "Nothing. If I could say that I liked something, it would be that I liked that my flight wasn't any longer than it was."
Cons: "Both planes (departure and returning) were old, dirty, and I have sat in more comfortable metal folding chairs than the chairs on these planes. Frontier charges for everything. They charge for seats that recline, charge outrageously for reclining seats with a ting bit more leg room, their beverage service is not free, only water is not charged. No snacks either. Luggage that is considered carry on at any other airline is charged at $60 at the gate and the flight attendants pander and really push passengers to apply for their credit card. Horrible all the way around and we will NEVER fly Frontier again. Ever."

Cons: "Never having flown with Frontier before, I had no reason to expect what happened. I found what I thought was a fairly good deal on Kayak to fly round-trip from ATL to DEN for a quick weekend with a friend. Little did l know, and certainly NOT because Kayak informed me during the booking process or anytime afterwards, that Frintier charges fees for *literally* everything. Want a soda...sure, pay $1.99. Want to choose a seat (not even a special one, just to know you won't be stuck in a middle seat)...sure, pay $13-$35 dollars per leg of trip. Want carry-on...sure, pay $40. For carry on. Really? So now my $261 deal has turned into a $367 dollar *ordeal*. Would have been better not using Kayak, and will definitely never fly Frontier again. Thanks for nothing."

Pros: "The pilot was nice and the plane was very clean."
Cons: "One flight attendant was yelling all over the plane instead of politely walking up to guests and informing them that the overhead baggage holders were full. Also, there seem to be a mix up with seating as before the plane doors closed, this same flight attendant allowed a guest to move to another seat, only for the ticket attendant to walk back on the plane and inform the flight attendant that she needed those seats. I usually fly with Delta, American Airlines, and in my 30 years of traveling have I not seen such unprofessionalism with regards to miscounted seats and the way the flight attendant handled those customers."

Pros: "Attention to detail. Outstanding miles membership program."
Cons: "Notta thing"

Pros: "I woke up to an email 31/2 hours before my daughters flight was suppose to leave Atlanta informing me that the flight was canceled. Called customer service where the man I spoke with was unable to or unwilling to tell me anything except that "yes it looks like the flight was canceled". His suggestion was to have my sister drive my daughter an hour and a half to the airport to see if there "might" be a flight available through another airline. Frontier did not have any flights going to or near RDU that day.Since my daughter had to be in Raliegh that day I spent the next 10 hours in the car going to get her. I did receive a refund but only because I requested one,otherwise they just don't refund automatically."
Cons: "Customer service represenitives are not very informative. The flights may be slightly cheaper but you have to pay for checked baggage as well as carry on bags. When checking her in the night before and picking a seat in coach my sister had to pay a "fee" for her seat, so an additional fee of $57 dollars for one bag and a seat.... Really?"

Cons: "Although there were warnings that "fees may be applied", I could not find how much those fees would be until 24 hours before my flight when I checked in. Before that, I had actively searched for how much I would be charged for my seat and my luggage both online and on the phone. No answers. I described this process to a lawyer who said there is possibility for a large class action lawsuit. I ended up having to pay $70 in fees (and will again on my flight back home -- probably -- again, there's no way for me to find out from Frontier until I check in). I don't mind fees, but they should be transparent. I will never fly Frontier again."

Cons: "I will never fly this airline again! The tix appear significantly cheaper on kayak, so we drove 2 hours out of our way to ATL in the early morning hours thinking it was saving $$$. Only to find at check in that it cost more to bring a small carry on than to pay for it to be checked! It was a west coast flight and it didn't even include a beverage in flight!!! No snack either. Thumbs down. It was certainly NOT worth the inconvenience of driving out of the way, and we didn't save any $ after all. The staff was not that friendly, at it took 30 mins for the frontier baggage carousel to even start up to get the heck out of there. Never again. If it seems too good a deal, it is!"

Pros: "Except for my "complaint," I thought the flight was fine. People were helpful boarding the play. The crew seemed friendly and chatty. I had a good seat (upgraded to the first three rows for extra expense). The monkey white wine was good and the flight attendant was witty and helpful. Thanks!"
Cons: "The only thing that caused me some concern was that the ATL gate on the printed ticket read 1 but the actual departure gate was 1A. At first I went to 1 and the flight information said Trenton and I didn't see the 1A or even go there to look. I found a helpful Delta service personnel who said, "Oh these people, they are never around to help the passengers. I'll help you. He went online at a kiosk in the general hallway and pulled up the flight as departing 1A. Sincere there was no way for me to know about this. I could have missed the flight. Either post someone to direct passengers OR put the correct information on the electronic ticket. Thanks."

Pros: "I was surprised that the flight was so pleasant. The ticket price was very good and even though I had to pay extra to select a seat, it was still a good deal. I didn't want to pay extra to bring a carry on so I packed minimally in a bag that I could fit under the seat as a personal bag. I paid for a drink, so cannot comment on the food. We left on time and arrived early. The desk crew and flight crew were polite. What was the entertainment...?"

Pros: "I didn't like too much to be honest.. the crew was friendly.. boarding was okay.. nothing is really standing out."
Cons: "Awful seats. They were WAY too small and I'm a small person (5'4ft 115lbs). They didn't even lean back and they were SUPER uncomfortable ... this airline is doing it ALL WRONG!!! The flight was only 3hrs long too.. and it left me with a very undesirable taste in my mouth.. the "complimentary" water didn't help.. they MADE me check my bag that would have clearly fit in the overhead compartment.. an extra $30 I wasn't expecting to pay.. the flight was so bad that I'm leaving the review.. I NEVER leave reviews.. so.. step up your game Frontier."

Pros: "Each frontier employee was kind and greeted me...usually with their name."
Cons: "I was in the middle seat and paid $6.00 to get a seat near the front of the plan as it is sometimes difficult for me to get to the back with all the pople and sounds as I have frequent vertigo. Right before take off I noticed several rows of seats completely empty and asked if I could move to one of those seats. Supprisingly I was tolld no. When I asked she said because people pay mor for those seats. For the comfort of the 2 other people and myself...I just thought it made since they were pretty much the same. These seats were not being utilized by anyone...no one had paid to sit there..not like Casper the friendly Ghost was on board and it would have made a more comfortable flight . Just found that a little peculiar. Some thing to think about if someone else ever asks????"

Pros: "I loved the price of the tickets. My children spend the summer between Iowa and Alabama. So we travel a lot. I normally drive to Kentucky to meet up with Grandma to let them go north for part of the summer. However, this year I have planned a honeymoon, and even planned going to Virginia two weekends back to back. I thought I would fly to St. Louis from Atlanta to cut down on the driving. (I tend to get sick on road trips anyway, a flight would be nice). I found these tickets for around $50 each. I needed 3. Got them. The flight to St Louis was quick. We landed 20 mins ahead of schedule. (Made my return trip great as I was back on the same plane and was sorta freaking out about making it back to the gate in time) Landed in St Louis walked to baggage claim met up with Grandma returned with time to spare. The return flight was the same. I did not like the seats. I ended up with a massive migraine no fault of the airline but I would have loved to have been a little more comfortable. It has been a long time from my last flight and this one. The price of baggage went up. (As well as tickets which is one reason its been a while) I did notice that the airline is wanting you to prepay for baggage when you purchase the tickets. In the long run makes in SO MUCH EASIER! And with the most recent issues with TSA and getting through security that speeds things up. I paid for one checked bag. And using the frontier site was cheaper than I would have been charged at the airport. Overall I can't complain. I did make it to and from my destination on time and safely. My bag was in one piece. The seats not being the best is a minor detail. Oh. And unlike some of the other flights this one did not offer free drinks and snacks. I've flown Southwest, and Delta I was offered a soft drink and a small bag of something. I was offered to purchase these from this line. Found it odd."

Cons: "There is a lot to complain about with this airline. I cannot comment on the comfort, food not entertainment because I missed my flight. Granted the flight missing was not the fault of the airline however I would have imagined that the staff would have told me in no way would I make my flight with the security lines the way they were. Once we made it through we ran the entire length of the airport to try and make the flight in hopes that they might delay the plane. That's is not the whole complaint because it happens. However; my bags flew with the flight I missed. The ticket agent assured us the bags would get to the destination and I could pick them once I arrived on the later flight (through a different airline). When I arrived NO employees where to be found. The "helpline" not helpful not even to tell me if the bags were there and lock and I could get them in the morning. Instead I was talk to condescending and rude, thanks to Kim in Colorado. I stayed the night over since my home is 3 hours from the airport. Next morning at 8:30 I call to speak to someone, helpline again unhelpful. Could not tell me when someone would be there or anything about my bags. I show up the airport. No staff. I waited for an hour and half for a ticket agent. Once I posted on their social media page that I was unhappy that person told me when they would be there and their hours. NOT THE HELPLINE but I already stood around picked up my bags and was out of there. I will never fly this airline. They nickel and dime you and have terrible customer service."

Pros: "The boarding process was pretty fast."
Cons: "Talk about hidden fees! You have to pay to choose a seat and pay for a carry on. You're allowed a "personal item" that has to fit under the seat in front of you, but what they don't tell you is that the seats are "sardines in a can" seats only about half as deep as traditional seats (so that personal item has to be smaller than you'd think). So let's talk about these seats. They are literally an inch thick. Like I mentioned previously, the seat part is only about half as deep as normal seats. It ended at mid-thigh for me and I'm short (5'3"). Accordingly the tray tables are only a hand's width, put a drink on it and that's about it."

Pros: "I like that the plane didn't crash. Other than that Frontier's service, from paying for your carry on and beverages and the ticket agents to the flight attendants was, I imagine, worse than a greyhound bus ride. I was able to download the frontier app and get my boarding pass, and make the flight (drenched in sweat from running through the airport) as they were closing the boarding door. Thank god for cardio and determination."
Cons: "There were five ticket agents at the counter when I got to the counter (an hour before my flight). All five of them were helping one person and talking to each other for about 10 minutes. Then one split off to help the next person in line - or just to get a laugh by telling the couple they weren't make their flight and they weren't going to drop anymore bags to the plane because we were close to the 45 minute cutoff before the departure time. Perhaps if they had been working as a team rather than a gang the whole lot of us would have been checked in on time. When I got on the plane (after asking folks in security if I could get in front of them and running like a madman through the terminal) the flight attendant was the pinnacle of passive aggressive annoyance. This was my first and probably last ticket I buy flying frontier."

Pros: "Zip"
Cons: "The hidden charges are an embarrassing way to do business, The flight attendant was inconvenienced by her job, and comfort level was what I would imagine a prison bus must feel like. My return flight was canceled do to weather in Denver, I am fully aware that this is out of Frontier's hands however I commissioned Frontier to fly my wife and I to and from Atlanta; that was the Job I hired them for, to and from. They did not complete there task. They canceled the flight 10 minutes before boarding and didn't offer us a hotel. We got a hotel, a rental car, and made the 1400 mile trek. I would at least expect a full refund. After getting home and relaying our story to friends and family, not one person was shocked at this. Apparently it is common knowledge that Frontier is the world's worst air line. Well Now We know."

Pros: "I liked that i made it to my destination."
Cons: "I do not like that the website does not clearly state that a backpack is a personal item. But here is the con, they say pay now for the bag or pay more at the airport! So of course you pay. On my return and upon picking up my boarding ticket i asked about my backpack and she told me it was a personal item and that it is free. She handed me a ready made slip of paper to call for a refund and said she would make a note in the system to this effect. When i called for my $80 refund i was told well the note in the system only mentioned your return flight so we will only return for that flight. Ok..ok. You see where im going with this. This is a class action lawsuit in the making."

Pros: "Great for traveling short distances. Got in and out very quickly. Very smooth take off and landing on the way back. We also got to be seated in the emergency exits, so we had much more space."
Cons: "Very small and cramped seating. Not for someone who is bigger. You have to pay for everything, but you don't need anything if you're only flying an hour and half."

Pros: "The guy next to me on the flight was really nice as were the flight attendants."
Cons: "I was charged twice for my bag. I had one bag. I went to the kiosk to get my ticket and was almost finished. I swiped to pay for my bag as a carry on and an error message came up and said to see attendant. I did. There were three people there who had no idea what was going on. I tried to explain what had happened and they kept interrupting me and telling me I probably was going to miss my Friday evening flight as it was overbooked. They asked me if I'd like to check my bag and I said sure. I agreed because I never finished my kiosk purchase or agreed to pay the fee on it. The attendant takes my card and swipes it. Then said "It looks like you paid twice. Call this number" and hands me a paper with an 801 number on it. The gate and departure time changed several times. We wee supposed to leave at 7:30 and didn't leave until after 8pm. This was an awful experience and I won't be flying Frontier again."

Pros: "nothing to like on a 14 hour mismanaged delay...We did get our luggage refunded. And $10 vouchers for food (not enough) and had to cue for these for a while..."
Cons: "after mechanical delay - they happen - not the issue... But, due to staff negligence on the DEN-ATL flight - my family and I had to suffer a stressful day, that could have been avoided. Issues: No proper updates on times. No one manning the Frontier counter at ATL from 4-4:30 pm - no assitance to get boarding pass to get in, now would the kiosk print it! Once there the lady was NOT helpful or empathetic. We had a tough time through security. Only due to another DELAY did we make this awful flight ATL -DEN. All the incompetence of a budget airline on full display. Get some better management in Atlanta!"

Cons: "A family of 4 with 2 small children sat behind my colleague and I on a 6:30am flight from ATL to LGA. There were 2 small children who disrupted my entire flight. Constant banging on the back of our chairs, slapping the trays up and down for 2 hours, slapping the plane windows, etc. After repeated efforts to ask the parents to have their children stop, the parents could care less about the disruptive behavior of their children. Complaints were made to the crew to no avail. The children were disrupting the entire 5 rows around them. These passengers should have paid for my and my colleagues flight, in addition to their flight, as they cause one of the worst experiences on a flight I've ever had. After this flight, I believe there should be a policy that if you have children on a plane, you should be required to pay more, allowing the people around you to pay less or opt out of having to be seated next to a passenger with a child."

Pros: "I have to admit, I liked the price. And now that I've flown the airline I understand why it has a low price. Which is okay, I saved enough money to cover my parking. I would say that 1st time customers might be unaccustomed to paying for your own beverages and snacks. The thing that struck me as odd was the staffs willingness even eagerness to have a confrontation with the quest. Like they took pride in putting passengers in their place for a few extra fee revenue dollars. The flight was okay, but Frontier airlines won't be my 1st choice next time."
Cons: "Rude staff! Baggage claim in Las Vegas was in another terminal, which I had To catch a shuttle to get to, which I'm sure is determined by fees the airline pays the airport. So the least expensive is not always the best thing."

Pros: "I liked how quick they were checking in and the lady that checked me and my friend in Denver to Atlanta was the nicest and the most helpful Customer Service Representative. She was very kind."
Cons: "The lady that checked me in was friendly and helpful at the front desk in Atlanta but the lady that checked my friend in from Atlanta to Denver that was working right beside the lady that was checking me in was so rude! We were both really tired because we had to leave at 2am to make it to our flight so we barely had any sleep and she asked my friend where she was flying to and my friend accidentally said Atlanta and the lady was just really rude because she made a simple mistake. She was snarky and condescending."

Pros: "The seats had a surprising amount of legroom, and the staff was nice (though i'm not sure why there were as many as a normal flight from another airline, since they don't do anything beyond the safety demo)"
Cons: "You are not adequately made aware that you will be charged for carry on unlike other airlines. And in doing so, the price of the ticket goes from being impressively cheap to being more than a flight from another airline that has more included amenities, like actual refreshements and free carry-ons. You also get charged for just selecting a seat, not a special seat, but ANY SEAT AT ALL. So the price you initially see when searching for flights is quite misleading. In reality, you should ad at least 50 bucks to any frontier ticket to get a truer picture of what the price would be for a normal passenger with a single carry-on that wants a particular seat."

Pros: "I have to admit that the seats were more comfortable than they looked. But I could not recline."
Cons: "The delays, several hours going to Atlanta and one hour coming back. It appears this is typical for Frontier. Also, $40.00 for the carry on. The deal I thought I had was not a deal. By the time I paid $80.00 round trip for two I could have taken a more convenient flight for the same money without paying for my carry on. I went with Frontier because I thought I was getting a deal. I felt nickled and dimed, pay for soft drinks??????? But the worse was the delays, with no explanation at all!"

Cons: "3 of us had checked in online. Dropping off our luggage we were treated as guilty scum by the lady behind the counter. Made to force our carry on bags within a box in front of a line of people behind us, then told we could only carry one bag on, and not purses also. She was critical of our carry-on sizes. Had to pay her EVEN MORE than we had already paid online which included 1 bag + 1 carry-on, made the cost even higher. Plane seats were cheap, flight very bumpy. We will NEVER FLY FRONTIER AGAIN! We had flown Delta to our destiny and we could carry our purses too, and she kept saying this isn't Delta! Humiliating customers doesn't win business. All rules were NOT on their website as if I had known I couldn't carry my purse also, would not have flown with them. Cheap plane interior gave worries of cheap plane crashing. Voice on plane said get out your debit card to pay for water! After home again saw 2 more tickets had been taken out of our bank account, tho' we were totally paid in full. Now have to deal with this!!!!!!!!"

Pros: "I am handicapped and need a wheelchair to get to the gate. After I arrived at the gate and was ready to pre-board, Frontier sent another attendant to wheel me down the ramp which was fantastic since most times I have to drag and stumble my way down the ramp to board. When the plane arrived at Dulles, there was a wheelchair waiting for me at the door of the plane-a first in many flights. I am grateful for the Frontier staff's consideration and assistance."
Cons: "Having flown Frontier before, I was aware of the baggage charges, so I try to prepare accordingly (pay for all baggage online rather than at the gate). I am a bit perplexed, however, at the seat charge. I am handicapped and must sit in an aisle seat where I can stretch out my leg to some degree. I was told that because I am handicapped I do not have to pay for a special seat, but every time fly Frontier, I have had to pay to get an aisle seat. What do I have to do to get the necessary seating without charge other than sit wherever they place me and chance a circulatory episode?"
