this was the THIRD time in four Alaska flights that were 2 hours late. Only one was due to weather. The intentionally posted each flight as only 1 hour and 55 minutes late so that they wouldn't have to give out vouchers. And then the flights all ended up more than 2 hours late. Makes United look like a premium carrier.

this was the THIRD time in four Alaska flights that were 2 hours late. Only one was due to weather. The intentionally posted each flight as only 1 hour and 55 minutes late so that they wouldn't have to give out vouchers. And then the flights all ended up more than 2 hours late. Makes United look like a premium carrier.

It was fine, mostly I was just happy to be on my last leg home. No in flight entertainment but that's forgivable since it was only a 2 hour flight.

Flight was cancelled, then rebooked on a flight that I was unable to get through since they had closed the gate.

This was likely the smallest, oldest plane I've been on. It didn't handle turbulence well and we were all jostled a lot more than I'm used to. At least it was a short flight.

Flight was delayed two hours; for an hour and a half flight?! And so we missed our connecting flight to Rome because of the long walk between the terminals. Hoping to hear back from Alaska about some compensation for our missed flight and night stay in Los Angeles.

Excellent service from staff at the gate as well as flight attendants on board. Seats had more room than many other airlines and if they were just a little better cushioned they would have been perfect.

Look at my previous review I just wrote on this survey. It was awful!

When I bought my tickets I up great my seats for extra $104 each seats 8A and 8B in the way back from Portland to Palm Springs they gave me the seats 15. I thought it was for round trip same seats . So I was very disappointed ☹️

Alaska Airlines adds time to flight time to make up for late departures. Also Alaska Airlines destroyed my suitcase and I had to buy another suitcase for return flight. Very frustrating and not sure I would fly Alaska Airlines again.

Landed and parked in back of larger jet. Cabin filled with jet exhaust. Left many with headache. I got sick to my stomach. Scrambled to find airsick bags

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

The flight crew was rude. We were in first class and no one even offered water until an hour after we were in the air. Horrible experience

American almost always Delays flights from Austin to Dallas and back. I cannot believe they have such poor service on this route. I was about to switch to American from Delta, but they gave me enough reasons not to.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.

Did not get the seat I selected and paid for.

My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.

Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄

There is no room, no gluten free options, or any free internet/entertainment. You have to bring your own tablet or smartphone because there are no screens.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan
