Pros: "On time flight"

Pros: "Plane had three delays. Apparently American mechanics are not allowed to strike so they have these fake or very slow mechanical issues."

Cons: "Muy bueno el viaje y las atenciones"

Pros: "Friend service"
Cons: "Food, seat comfort."

Pros: "Nothing-never made it."
Cons: "3 flight cancellations."

Cons: "Flight delayed three hours."

Cons: "Last minute (after partial boarding) they had to switch planes due to a "maintenance issue" which I would think they would have caught earlier."

Pros: "The announcements were clear and the captain did not mumble! Not sure what happened at the airport but we had issues with ground crew not coming to help park us. The captain made sure we were informed and it didn’t really add to much to our time."

Pros: "Very good crew."
Cons: "Hate the kiosk check in"

Cons: "One crew member was rude, another confused. The grey blazer crew member was friendly"

Pros: "I like the fact that I made it to London alive. The turbulence was so bad and the pilot never came on and reassured us I was shaking and nervous all the way across the ocean"
Cons: "The boarding issue to me is a big problem you should put the conditions of the ticket up front and center for example boarding last when you are on an international flight with bags that need to be put in the overhead is a big problem having to pay for each seed internationally for each leg of the trip made my ticket just as expensive as if I had bought it from a regular company never again will I use your service rip off rip off. Once you buy the ticket then you send clarification letting the passenger know they have no rights I had no right to anything I was wondering if they were going to tell me I had to clean the plane in order to be transported from New York to Spain. A satisfied customer is a repeat customer you got over on me once but never again"

Pros: "Check in"
Cons: "Missed connection"

Pros: "Great service and on time flight."
Cons: "Just wish sears would be a bit wider and comfortable. They are not bad but I am sure could be more comfy because I am not skinny."

Cons: "Flight cancelled and had to travel 60 miles at my expense to a different airport to get another flight same day"

Pros: "Flight was not full. We flew on a Tuesday in September and maybe that is a good time to fly. Also, there was slightly more room in our seat than expected. I am 6'1' and 216 lbs so air travel in coach generally approaches medieval torture for me."
Cons: "The seat was uncomfortable."

Pros: "See above"
Cons: "See above"

Pros: "The fare rate. The boarding crew were good. The onboard crew were not too friendly. No smiles."
Cons: "The seats seem to be tight. I’m only 120kbs and 5’ and yet I’m having a hard time squeezing into my seat. The food was ok. Entertainment is a big zero. The plane is okd style."

Cons: "I was in such pain by the time I left this flight, the seats were horrible."

Pros: "Our flight was delayed somewhat by a service door not completely latched. The plan returned to get it closed, then was promptly airborne. After the delays, the flight actually made it to our destination by our scheduled arrival time."

Pros: "The crew was very friendly and helpful"
Cons: "The delay"

Cons: "The flight was cancelled and our party was stuck for 2 days without a returning flight."

Cons: "It took 30 ish minutes to wait in line to speak to to an AA rep about what my next steps were to get home from Dallas."

Cons: "no complaints"

Cons: "Very disorganized. Why was I put on this terrible American Airlines plane? My headphone outlet was broken, the plane was very uncomfortable, the boarding was disorganized. I thought I paid for a British Airways flight?"

Pros: "On time"
Cons: "Paid extra for seat and I don't see why. It wasn't any better than lower priced seats. American boarding process is unnecessarily complicated. Board from the back forward like Alaska does."

Pros: "Great flight & got in early"
Cons: "N/A"

Pros: "Left on time Nice flight attendants Arrived early"
Cons: "Runway time in New York"

Cons: "Very poor boarding. Crew late but did not start screening and checking passengers until late. Had to ride bus to plane and walk a short distance in the rain which was moderately heavy."

Pros: "Great service and friendly stafg"
Cons: "Loved the yourt for breakfadt...rest of it was ok"

Pros: "Everything, the plane was big and comforting, the fly attendants were very courteous and professional. Awesome fly."
Cons: "Nothing"

Cons: "Plane got cancelled. Missed my other flight. Spending $100 more that was unnecessary"

Cons: "Lots of turbulence."

Pros: "As a fat guy, I really like these newly built AA airplanes with huge seats. Two great flight attendants, too (a rare thing this day and age). Better than average coffee for an airline."
Cons: "Terrible turbulence. I know it's not AA's fault, but still, despite how nice the plane and staff were, I was sweating bullets for two hours!"

Pros: "the airlines did try to accommodate by giving us optional flight when our connecting flight got cancelled"
Cons: "No meal options for vegetarians for breakfast. They just gave everyone a turkey sandwich. Rude, frustated and sarcastic staff"

Pros: "Quick boarding, no shuttle! Pilot very informative"
Cons: "We were never asked for beverage service.Also when arriving and exiting to retrieve our bags when congested with baggage no room to stand and wheelchairs all at once trying to exit up ramp.Very unorganized and chaotic."

Cons: "delay's............................. .......................................... ........"

Cons: "Required to check carry on because of full flight, bag did not make connecting flight. Required to return to airport to recover 6 hours later (additional 50 mile drive)."

Pros: "Free beverage"
Cons: "My bag was lost and it still hasn't showed up at the airport. Seems like I would get some kind of credit of some kind for this inconvenience."

Pros: "Flight was on time."
Cons: "My luggage was lost!!! People were sympathetic but no apologies or compensation Also, we were forced to pay extra for our seats before we were able to print boarding passes. My husband and I were not able to sit together which was upsetting to me."

Pros: "Flight crew very welcoming, flight was pleasant."
Cons: "Seating a bit tight. Didn't offer any snacks only ice water."

Pros: "Nice crew"
Cons: "I got same thing pretzel very salty"

Cons: "It was terrible. A missing flight attendant caused an extra delay in departure. Missed connecting flight. American Airlines was not prepared to assist all the stranded travelers. Had to spend night in the airport until I could get on a flight the next day. This was not what I paid for."

Pros: "From Seattle to DFW, we had the best flight! Brand new plane with individual entertainment screens!"

Cons: "I purchased a round trip ticket to Miami for my infant son and I to accompany my wife on her business trip. First off, there was a 2.5 hour delay. The flight was overbooked. The lady at the ticket counter would not switch my seat to be seated next to my wife and 4 month old infant. Luckily the gentleman beside her was willing to switch seats so that she could comfortably breast feed our son. My checked luggage was severely damaged. The side of the luggage was caved in and one wheel was completely ripped off while the other was partially damaged. A cart had to be rented in order to transport the broken suitcase through the airport to the rental car service area where we picked up our car. The infant car seat belonging to a $180 traveling system was damaged and is missing pieces that secure the broken canopy. We were rudely advised by a staff member to file a report as she pointed in the general directional of a line a mile long. We have been advised by the manufacturing company to discontinue the use of this car seat because it is no longer considered safe for the baby to travel in. Should we ever be involved in an accident, the car seat would likely fail to ensure the baby's safety due to the mishandling by American Airline employees. Unfortunately since the flight was ridiculously delayed and my son was ill, we were unable to file the report. My wife has since contacted American Airlines via telephone and intends to write them a formal written complaint."

Cons: "The fees for the baggage are ridiculous"

Cons: "Frontier services is the worst."

Pros: "Nothing"
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"
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!"
Cons: "Nothing."

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: "Paying $3.00 for a $.50 soda, paying for carry on bag. very uncomfortable seats, no entertainment at all for such a long flight. need I go on?"

Cons: "We arrived at the airport with the standard two hour timeframe. The line just to check bags was so long, it literally was winding into the airport. I'm not sure how people actually made their flights. We were lucky enough for a tip that the curbside checkin was shorter and faster. Made it to our flight with 20 minutes to spare. Crew was not very personable and not accommodating to families. Frontier also nickel and dimes you to death now. You have to pay for seat assignments, which as a family of five is an unfortunate necessity. Also have to pay for carry on baggage. I get trying to save on flight room, but the backlog it seems to be creating for checked baggage is beyond ridiculous."

Cons: "Kid vomit"

Pros: "Direct flight"
Cons: "Seating is awful, like sitting on a brick NO RECLINE in economy seating and small. Avoid Airbus A321 planes whenever possible"

Pros: "Really helpful flight attendants"
Cons: "Very small (smaller than my kindle) tray tables. It was a very loud plane as well"

Pros: "Ahead of schedule"
Cons: "No drink service, no entertainment, very expensive. Never again"

Pros: "The crew was friendly."
Cons: "No in flight snacks, entertainment, and seats were not very comfortable."

Pros: "Nothing"
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."

Pros: "Price"
Cons: "Paying to carry on luggage."

Pros: "early arrival. smooth flight"
Cons: "you charge for everything!"

Pros: "Nothing"
Cons: "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."

Pros: "Nothing"
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: "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."

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."
