No tv, movies for a 6 hour flight! Worst airline I have ever travelled!

It was great; it was on time, everything went smoothly, the crew was excellent. It was just uncomfortable for the usual reasons; completely full fight, could barely move because the space was so small. The expected stuff with every airline.

Ground crew was great in Austin, flight crew left a lot to be desired. Not particularly friendly, helpful or nice.

My baggage was in another flight, anit was delayed for one hour.

They canceled the flight 30 minutes prior to departure without any heads up.

Like South West(2 check in baggage free) if Alaskan Airlines could give at least one check in baggage free then it would be great.

Up on arrival, due to twisted ankle, I wasn’t able to walk. Requested for a wheelchair. They immediately asked for it. After 10 minutes wait a young man named Carlos picked me up at the gate, got my baggage and took me to the pick up area. It was a great service. Thanks Alaska Air line

Staff great. Tight seating. Pretzels and drink same as any other airline.

We had a very scary attempted landing in Palm Springs and were redirected to Ontario. It was a stressful flight.

Every thing means , crew, service, timing, boarding is very good.

The CX617 from HK to BKK was delayed more than 1.5 hours.

American Airlines continues to price it can provide the least comfortable passenger experience in the air. This legacy carrier rivals the budgets for both terrible seats and inadequate amenities. I am a 5’7” woman who is not wider than a coach seat (even on these narrow bodied aircraft). My 3.5 hour flight was terribly uncomfortable because the leg room is inadequate (my knees hit the seat on front of me even when it was not reclined); the seat barely reclines; and the foam padding is worn thin to the extent one can feel the metal supports of the seat. Add to this the fact that the aisle is super narrow, so that the drink cart literally scrapes the arm rest of the aisle seat. It’s basically torture.

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

We experience delays on departure and connecting flights resulting in 14 hour to our next departure. We were accommodated with a night's stay but was only provided a 12 dollar meals accommodation. The airlines rules state.at least 50 dollars. In any case, it can not make up for the whole day missed on our vacation in Sydney Australia.

I can say I will not be taking this airline again any time soon. Seat were uncomfortable and too tight. Lack of chair screen and little overhead space.

Plane felt so crowded and tightly packed. The chair itself was not comfortable.

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q
