the departure got delayed due to SJC situation, but it was a quite good waiting thanks to Alaska airline teams.

The flight attendant in the back of the plane was barely understood as she rushed through instructions to the point of being intelligible. She had a bored demeanor in her delivery.

Staff seemed genuinely nice, not just going through the motions.

The pretzels are awesome. The free movies are excellent. The plane crew was amazing. The Austin airport lounge was too small and overcrowded. There were not enough seats. And the boarding staff was not as friendly.

I like Alaska Air fine. Great crew. Late departure still arrived on time.

Excellent service and prices. I was not award of inflight entertainment.

They gave me a seat with extra leg room. But they didn't offer me anything to drink, just because it was an hour flight

I was happy with the flight. It was too short for food and beverage service. (no problem) We left SLO on time and arrived in San Diego on schedule.

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

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.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Crew was not friendly when I went to request a seat change.

Really impressive staff at airport and on plane, especially given how busy it was

Was a great smooth flight from Detroit to San Diego.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

Too many fees (but that seems to apply to all airlines nowadays)

For a 22 minute flight all you expect is for it to be safe and comfortable

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

Over two hours wait to get wheelchair assistance from arrival to the departure gate for LA was unreasonable even though there appreared to be heavy demand.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

I was delighted that we were able to get on the 4:40 pm flight rather than our original booking at 6:55 pm!! Other than that, the flight was comfortable and landed early😊

The flight and crew were fine. The entertainment- the sound was so bad through the headphones I could barely understand it and it was a show I had seen before. The food might have been fine but having to have an account with united in order to access the app in order to pay for the food was rage inducing. I had entered my credit card info at home and logged in as guest but that wouldn’t allow the “wallet” tab to open in the app. And then the wifi was so bad that it took about 45 minutes to fully log in and get all the info working at which time I missed the food. You shouldn’t have to give your address, email and phone number in order to get a hamburger.

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

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.
