Scores according to KAYAK customer reviews
Cons: "Missed flight in DFW. All other flights full. Had to reroute thru Miami"
Cons: "I never felt like writing a review but I feel like I should let other families with little ones know. My wife, 2 year old son, and I was boarding at the gate and they couldn't scan my son's boarding pass. They quickly went over to the computer station and gave my son another pass. We went to our seats and found out someone else is in our 2year old seat. Apparently they gave the seat to someone else at the last second because up to the point when I printed our boarding passes at the kiosk, our seats were still together (and I paid $41/per seat extra to try to keep us together). The other customer was nice enough to switch with our son so were able to stay together at the last min so it goes to show AA priority and service."
Pros: "New planes, in seat entertainment"
Cons: "Very hot plane, never cooled down."

Pros: "Smooth flight"
Pros: "Honestly I enjoyed every little moment. I haven't traveled to Atlanta in 9 years and let's say traveling with AA is great. Starting from the check-in up until baggage claim in atl. Everything was speedy! I'm so happy that I went with AA I had a spectacular arrival."

Pros: "The pilot apologized for the delay and promised to get us there as quick as he can, if that was possible. But, it was thoughtful of him."
Cons: "Although I was informed that the flight was delayed, it was too late, I was already at the airport. A two delay ended up being three hours delay. When it was time to board, we had to wait for a crew member, further delaying boarding. Finally on the flight, I was served cold coffee!!! There was no blanket!"

Pros: "The planes people and service."
Cons: "I missed my flight in Atlanta heading to LA on my way to Brisbane, Australia on Saturday 16th July. The ground staff wasn't at all helpful in trying to get me on another flight and in fact sent me to Delta! The lady there couldn't have been nicer and more helpful. Sadly I wasn't compensated at all and had to pay to re-book the flights on the Sunday 17th. On my return from Brisbane, American Airlines had cancelled my flight to Atlanta as they said I was a 'no show' heading out. Thankfully I was able to get a seat on stand by. So, no I'm not a happy customer."
Pros: "thiughy it was a good price on the fare. Now I know why"
Cons: "The representatives and staff at your LaGuardia airport need some serious customer service training. Very rude - no one seemed to know what was going on. Flights were pulling up they rebooked and they were fussing at customers. Understaffed and delaying and canceling flights. Would not recommend to anyone to fly with them. Even on connection changed gates 3 times. So customer unfriendly!"
Pros: "The Professionalism"
Cons: "There is not nothing to say"
Cons: "The crew on the return flight home were a bit nasty..."
Cons: "This flight never happened due to an airport and schedule shift caused by the first leg being cancelled."
Pros: "The pre recorded safety instructions. Very friendly crew, they really worked hard the entire flight."
Cons: "Small seats really put my back into a bind. All I wanted to do was sleep and I couldn't because of the pain. It took forever to board the aircraft on top of being delayed over an hour."
Cons: "Security going through my luggage over a candle"
Pros: "Flight and flight crew were wonderful. No problems at all."
Cons: "I was stranded in Miami airport because I was bumped from every flight. I was late to my 0500 flight from Houston because I circled the airport 3 times looking for the rental car return. Tried to check in 5 min. before boarding time. Was told I had to be rebooked. No problem. Next flight left about 0830. Made it to Miami. Was bumped every flight that day. Was #1 and #2 on waiting list for last 4 flights of the day, but was not given a seat. Others who were either employees or also waiting somehow got a seat though. How is this? Had to sleep in airport and pray to make the AM flight. I'm so disappointed that we are not picked in waiting order. No, all the others did not have priority seating or something. Passengers talk while waiting, so I know I'm not assuming this. We also heard the employees conversations about "hoping to get a seat too". None of us were told our new flight assignments were "stand by" either. If I was aware of this, I would have made another flight arrangement or could have driven to my destination! I paid for a ticket, yet employees on stand by flight get priority. Not right!"
Pros: "Flight from LGA to ATL was good. No complaints."
Cons: "Turbulence. I understand this is out of the crews control."
Pros: "The was late and my logged was late i lost my transportation to Fort Benning."
Cons: "The chairs are to closed to each other. America Airline like to change the bording gaited to much."
Pros: "I loved the entertainment options"
Cons: "I did not like"
Pros: "It was a good nice ride. The employee was nice."
Pros: "Nothing at all"
Cons: "I had the worst experience of my life. I was trying to go to Miami for my dads funeral an made a mistake booking the wrong airport an I didn't know until Tsa told me I had the wrong boarding pass. So when I tried to have American change the airport so that I can take another flight not only were they careless about my loss nobody tried helping me rebook they just told me the only thing I can pay $200 plus another ticket for about $600 or use another airline it may be cheaper i thought that was so rude an they would have a little sympathy but they did not. I end up spending $328 an using a whole other airline for a honest mistake I'm just very dissatisfied an disappointed that American airline would do that to me on one of the hardest times in my life an I hope they never treat anybody they way they did me."
Cons: "They forgot too board snacks and not enough leg space"
Pros: "I was reassigned to another flight due to problems with the airplane"
Cons: "There were problems with the airplane. I left Miami 5 hours later after requesting to be put on another flight."
Cons: "First off, the flight was delayed. And then when I was boarding the plane I was forced to check my carry-on bag. They claimed there wasn't any overhead storage left, however when I got on the flight, there was still a lot of room. Very disappointed I had to be delayed at baggage claim for no reason."
Cons: "It was late. On Wednesday Day 2 of my travel due to American canceling my flight the previous day. To add insult to injury, this flight was an hour late. I think you need a new slogan: "American - the unreliable airline""
Cons: "Flight canceled 2 hours before boarding. Was automatically swapped to a 5am red eye flight with layover. Had to find somewhere to spend the night last minute, and missed work on Monday. The airline never contacted me about the change."
Pros: "The space"
Cons: "ThE delay"
Cons: "The fees for the baggage are ridiculous"
Cons: "Frontier services is the worst."
Cons: "Got to the airport at 4am for a flight that was supposed to leave at 6am. The flight finally departed at 11:40am. I missed my non-refundable connecting flight and had to book a new flight. All in all I probably lost $300 because of this situation. On top of that it was my birthday."
Pros: "The price is good"
Cons: "I don’t like the chairs"
Pros: "The price"
Cons: "The seats were uncomfortable, having to pay for a carry on"
Pros: "Ease of boarding, and the fact that we took of 30 minutes late and still landed just about on time"
Cons: "Seats are a bit hard and don’t recline at all"
Pros: "Very friendly flight crew!"
Pros: "Nothing. Not even the refund compensated for the lost time and additional expenses incurred from Frontier"
Cons: "6 hour delay. Didn't board plane and still lost our bag"
Pros: "Once on board all was well"
Cons: "Flight delayed. By 1.5hours"
Pros: "It was a direct flight and left on time"
Cons: "Paid extra money for my carry-on and check bag. Bad cabin flight crew placed my carry-on in rear of plane though I paid for row 2 seating. They wouldn't let me use overhead cabin for row one or 2 and said it was for row one passengers as they have no under seat storage. No reason to pay for a seat upgrade I now know. Never again on this airline."
Cons: "Comfort was almost unbearable"
Cons: "Kid vomit"
Cons: "Staff was unpleasant. Uncomfortable seats."
Pros: "The man in the seat next to me decided he didn't want to sit by me, so I had more room to spread out."
Cons: "At the gate, after our flight had been delayed almost two hours, their was only one employee working. This extended our boarding time considerably. One of Frontier's main selling points is that they spend less time on the ground, allowing for them to charge less for airfare. Just not my best experience flying."
Pros: "I like that the flight was nonstop early morning and late evening. That's it!"
Cons: "I hate all the fees. It is a wonder Frontier airlines is not charging to breathe their air, I hate that! The seats are too tight, and the airplanes are old."
Pros: "The flight crew was very friendly. I feel like they put a lot of focus on ensuring they're friendly, responsive and have a nice sense of humor to make up for their airlines terrible timing and equipment."
Cons: "This was my return flight on Frontier and although not as bad as my first still pretty horrible. Upon arriving at the COS airport we were greeted by...no one at check in. We were told they were on "lunch" and we couldn't drop our bags until they finished. There was at least 15 people waiting on Frontier reps to show up and check us in. After that time suck flight was delayed again. Plane was filthy. After looking over the total for the flight it really doesn't save you any money after all the extra fees and poor service. I'll pay more to fly on an airline that shows up."
Pros: "Weather is fine here, but a delay in a different city turned into 4 hours of waiting. The $10 voucher really made me feel better though! Total disorganization, it all stemmed from a delayed flight 5 days ago that snowballed into this. Crazy, only fly these guys if you have no other choice."
Pros: "Nothing. My flight was cancelled 5 mins before departure with no explanation."
Cons: "Nothing. My flight was cancelled 5 mins before departure with no explanation."
Pros: "Smooth flight very pleasant crew."
Cons: "My seat did not recline and the person in front of me did get to recline which made my space even smaller...."
Cons: "The boarding process was hectic and not organized. Seats extremely uncomfortable. Flight was freezing the entire time. Having to pay additional for every single additional bag brought on board."
Pros: "We left early and arrived about 20 minutes early"
Cons: "Very uncomfortable seats"
Pros: "I like that they let us board in the beginning with a child so that we could get situated before everyone else was on there."
Cons: "Paying for my seat to be by my two-year-old grandson. Paying for a pop or beverage on the plane."
Cons: "Paying to carry on luggage."
Pros: "early arrival. smooth flight"
Cons: "you charge for everything!"
Pros: "Nothing. Will avoid frontier at all costs. I'm looking at cancelling my frontier return and rebooking with literally anybody else"
Cons: "Was delayed, no food/drinks in terminal. Very uncomfortable seat. Extra charge for everything. Was not able to understand the safety speech the flight attendant did... Kind of concerning"
Pros: "Getting home safe"
Cons: "Frontier airlines from start to finish was a terrible experience. My first time flying. I will not go into details of my experience in while on the plane the person beside me was complaining about frontier. I got on the shuttle to go home and another couple wS pissed off over Frkntier and the person across from us chimed ion they would never fly again within Frontier. It was just bad from use of their website to the checkin process and the flight."
Pros: "Frontier encourages you to check your bag by offering a lower fee for checking than carrying the bag onto the plane This made getting into and out of the plane so much quicker The seats were comfortable enough and I had my own food and beverages so did not need to purchase any."
Cons: "My reasonable priced ticket went up $104 by the time I paid to check my bag and pick a seat. I would rather gate check my bag and get it when I exit the plane because it took over an hour for it to come to baggage claim."
Cons: "Frontier is a bait and switch operation. They offer discount fares and when you get to ticketing you discover that they charge $40 for checked bags and $45 for carry on bags!!! I can understand the checked baggage fee only if it was made known prior to purchase but charging more for carry on bags. Also, the staff at the ticketing counter are rude and obviously selected and trained to make sure that they get every penny of their ruthless money. I have flown my first and only flight with Frontier and will never do so again."
Pros: "The crew was very courteous and attentive."
Cons: "Significant delay due to computer problem. Very uncomfortable seating."
Cons: "The fact that it was sappoesed to be canceled and rescheduled and it was NOT. BOTCHED !!!!!!!!!!!!!!!!!"
Pros: "The boarding and deplaning process was very fast. Most likely this is due to the fact that it is less expensive to check a bag than to carry one on, so there were way fewer bags overhead than on a typical flight with another airline."
Cons: "Be prepared to pay if you want to eat or drink. All items are for purchase only. I don't think that my seat reclined at all (and I wasn't near an exit row), so no sleep for me on my almost three hour flight."
Cons: "Self check in/boarding pass printers would have been nice, waited forever in line to do that because I don't own a printer.."
Pros: "The tate"
Cons: "Paying for bags"
Cons: "Flight was delayed over 2 hours. Was forced to pay for an upgraded seat, even though I had already checked in. I will not fly with frontier airlines again. Customer service was neither friendly or helpful with answering any of the questions regarding the flight delays."
Pros: "Crew were arguing with passengers over seating arrangements and when it came time to throw out garbage at the end they completely ignored half of the rows. Even after the lady next to me yelling to get their attention."
Cons: "See above."
Pros: "Crew was great"
Cons: "Seats were awful no room my husband is 6'6 and seats don't recline at all.. We took a red eye and had to try and sleep sitting straight up.. No entertainment not even music"
Pros: "We got to destination 30 mins ahead of time."
Cons: "No leg room and the seats don't recline. No free snacks or drinks. Not even water."
Pros: "Good price; easy to book; easy boarding; very punctual (everything on time)."
Cons: "Plane was very uncomfortable and cramped; Charged extra for everything (I thought they would ask for more money for carrying my wallet and a pocket comb.). Traveled as a couple; had to pay extra to insure that we could sit together. Are you kidding???"
Pros: "the flight was on time both ways."
Cons: "excessive bag fees. non reclining chairs. having to pay for soft drinks and snacks. LONG loudspeaker announcement trying to sell us their credit card deal. No TV or media available."
Pros: "Arrived early - fun crew."
Cons: "Seats don't recline - slow de- boarding process."
Cons: "Lots of screaming children, but I had to fly to Orlando."
Pros: "Hummm, landed safely! I do like that "carry on" people have to pay extra."
Cons: "No reclining seats even after paying an extra $50 for the good seats (and to ensure sitting by spouse). Cannot even get a glass of water without an extra charge."
Cons: "You charge extra for everything."
Pros: "I was impressed with the patient attitudes of the crew and the quick thinking to find a solution when we were stuck on the ground for two hours during the blizzard because of power outages that made us unable to finish fueling the plane. The quick turnaround of finding another solution to fuel (flying to an operational airport with the fuel we had), and getting the alternate flight plan to Kansas written and approved was very impressive, and saved my trip."
Cons: "The worse service ever; Would not buy tickets from them again... You get what you paid for - Baggage and seating are extra fees"
Cons: "Another frontier flight delay due to illogical, unidentified "paper work.""
Pros: "Long Flight Delay Due to Weather, Strong Thunderstorms and Tornado warnings. Handled Delay well and boarded when appropriate."
Pros: "Boarding was fast. The only slightly negative I noticed was the window was very dirty on the inside and the seat back in front of me was too."
