There's no "complimentary" snacks on Frontier. Which is fine, their flights are cheap and comfortable and the snacks are affordable. I also don't really appreciate having to pay for a carry on. I knew about this so made sure my bag would be considered a personal item, but I just don't know how I feel about that as a backpack may not even fit under that seat. But again, the flight was cheap. So, I don't know.

2nd row had plenty of leg room, nice new jet, Nice flight attendants, smooth flight, on time, made it to my destination safe. Successful flight! TSA Pre-chek was nice.

Idiot in front of me reclined his seat. Plane didn't get catered overnight. Water only.

Website would not let me check in the day before or the morning or my flight. There was an error every time and I almost got to the end once. I could not change the time of my transportation and arrived 10 minutes past the check in deadline (an hour prior to the flight taking off). I was refused access to the flight and offered a flight 5 hours later. The staff was rude and not helpful. I had heard negative things about Frontier and now I know why.

Its a scam! They act like they are giving you a break by having you buy cheap flights but in reality it costs more than a bit more expensive flight. I had to pay $45.00 each bag no matter if it was checked or carry-on. In total round trip I paid $180.00 extra just for my husbands carry-on as well as mine. Must add that our flights together cost 286.00. We should of went with American Airlines. On top of that we couldn't select our own seat if so, we had to pay extra, so we had to sit separated from each other. It was ridiculous! Never Again with this company!!!!!

Almost everything. Only the food was lacking. I like their new planes. The outlet at the seat in coach. The magazine options at the seat as well. I did not look at the entertainment so I will not rate that. The crew was professional.

Just the food options. Ginger snaps was what was served for food and a beverage. I suppose this is what obtains on most airlines these days but can't I hope for something more like maybe a sandwich? AA has the opportunity to set themselves apart in this area.

Nice crew

I booked a LATAM flight for a 10.5 hour flight specifically because they have better in flight entertainment. I arrived at the airport and found it it was operated by AA. 10.5 hours with zero in flight entertainment. HORRIBLE EXPERIENCE.

I liked the expediency of being rescheduled for another flight and the kindness of the American Airlines staff. When I first received my boarding pass, the pass listed gate A24 as the one where my flight was scheduled to depart. The plane destined to depart from Dallas to LAX did not show up. However, a few of us were kindly offered a cot and blankets to sleep on. The next morning I folded the cot and the blankets and found an American Airline staff member who swiftly rescheduled me for another flight to LAX. She did state that the original flight had departed at 11:15 p.m.

From around 6 P.M., December 11, 2017, I was at gate A24 - the gate listed as the Departure gate for my return flight to Los Angeles. The last flight that left went to Saint Louis, I believe. There was never a flight to depart from Gate 24 to Los Angeles. I believe the gate may have been changed and for some reason, those who were at Gate 24 were not informed. Also, the travel instructions on the advertisement for scheduling the flight mentioned the ability to carry on luggage for no additional charge. When I received my boarding pass, it stated I was only allowed to carry on baggage that would fit underneath the seat and not in the overhead bin. I had to pay to check my baggage that I thought was free. In spite of the changes, the flight was a good flight. Thank you
