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

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.

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!!!!!

No outlets to charge your phone, and the tv played the same movie over and over. The meals were also cheap. Didn't like any of them. Should have flown southwest or delta.

The seats were incredibly uncomfortable! Also, many people did not understand how to turn off the televisions, so it was pretty distracting to have so many monitors going when we all trying to sleep.

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.

No hassle of changing terminals in JFK, no bagagge claim, AA check-in-this time, was a "good luck"....Connection in Helsinki, very quik!

Finnair flight AY06 are old aircrafts. Every other in-seat monitor was out of order, flight attendants could not do much. That created mess for passengers, trying to move their seats to the ones with working monitors.....

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
