I went Premium otherwise it would have been a long wait. On board I only asked for a cup of hot water and got lukewarm. Cabin crew have poor to no service. But great flight; it went smooth.

I went Premium otherwise it would have been a long wait. On board I only asked for a cup of hot water and got lukewarm. Cabin crew have poor to no service. But great flight; it went smooth.

Alaska airlines is the best. Best customer service, crew, and value for money.

Outside Sky cap would be helpful! No entertainment (TV screens)

Great no problems. Very friendly. An hour ahead of schedule

flight was canceled and we were re routed all day. had a nice weekend planed in San Diego. Plans changed and we lost a day and spent the day flying.

The reduced size overhead compartments were a surprise. They keep getting smaller and smaller while amenities keep getting fewer.

My flight was on schedule, ground crew looks overworked, flight crew was great but refreshments could be better. The plane was clean and fairly new. Seats were comfortable but leg room was tight.

Always reliable customer service. Especially, the extra care on a long flight back to the Mainlaind.

Good flight. Pilot kept us well informed and attendants did a great job. Negatives:,1) little snack packs are far too expensice; 2) arrived early but waited 1/2 hr+ to get to our gate to deplane!

Great ! The counter staffs in Boston helped me to wrap my broken luggage with a plastic bag to prevent my stuffs falling out.

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

Poor availability of food. Cold cabin temperature. Extremely long waiting time for a flight attendant to respond to a call button signal.

2.5h delay due to unruly passenger in first class. Had to be removed from the flight. No food unless pre ordered. Didn't know we would need it because of delay.

This time my flight was smooth and uneventful. They started boarding even earlier than it was scheduled. I was pleasantly surprised. Thank you!

Only my carry that was taken and found it in my final destination
