Didn't buy food and did not use entertainment as these were not the purpose of my flight.

The first leg of the trip was excellent. Lovely flight attendants and comfortable plane. The second leg left a lot to be desired. The flight attendant was rude when I asked for a Diet Coke, the boarding required quite a long walk and the plane was crammed and uncomfortable.

Flight attendant was awful, I felt second hand embarrassment with every one of her interactions with people onboard. She was so incredibly rude every chance she got

Great flight - efficient and cheerful team on board, at SFO gate. Also, PAE (Paine Field, Everett, WA) is a great little airport to fly out or in to!

My flight wait is 3 hours delayed due to Unknown reason. We waited a very long time in the tarmac. Our flight 24 was scheduled @ 7, therefore we left my house at 330 to park our car. We were at the gate @ 530, then we were told at 6a that it will be late , we boarded at 930 but did not take off until 1015. Therefore my arranged pick up in JFK was cancelled because of no show. Before all these I got an email offers of changing my flight to a different date which I took a day earlier. I will never again take Alaska Airlines, very Inefficient and Disappointing.

Such great crew, from checkin to the plane. So friendly and helpful, I was genuinely impressed.

I was sitting towards back of plane and the flight attendants I thought spoke unusually loud for an evening flight. They chatted and chatted all night long and it seemed odd to me that they didn’t try to lower their voices. It is annoying as a passenger to hear all their conversations.

Staff at Gate desk were helpful. My connecting flight from the first part of my trip Kona to Seattle was late. I had to run through SeaTac Seattle to catch my flight to San Jose. They made an exception to let me board. On my return trip San Jose to San Diego and San Diego to Honolulu the same thing happened. One flight arrived late and I had to run through the terminal to catch my connection. There are no Gluten-free & Vegan options meals and snacks to purchase.

Had to pay $8 for internet wasnt cool, no tv’s, had to use phone to watch movies, no food choices seemed available unless u ordered in advance maybe I'm wrong about that but seemed that way, no snacks were served. Seemed a very bare bones flight. But it was on time and safe so that was good

We were singled out, greeted and helped with check-in at the busy airport. They offered to take our bags there and gave no fuss when we said they were carry-on. With United just last week I had to put up a fight just to get onto the flight with my one authorized carry-on.

The entertainment package was vast and the selections were very current. Keep updating it was great.

The seat was so hard my tailbone was aching The crew was kind of a b**** because I made a joke that I didn't care if they close the door I total c*** when she was trying to f****** act like she was mad at me because I said that The flight was bumpy. Sure you didnt have control over that.

4 hours late, including over +1 hour waiting in plane to take off. Baggage left behind too.

While waiting to claim my checked luggage, I discovered the airline had lost it. After a long wait and inquiries, I discovered it was on another flight. Fortunately, the airline finally sent my luggage home.

Was not able to watch most shows on the entertainment site. They would not load

Our flight was 1.5 hours delayed. There was no weather for the inbound flight, so I don't understand why. This meant a VERY late arrival and only a quick nap before my morning flight.

Delayed flight, so I switched fights to SFO to Phoenix , Phoenix to DSM. Excellent service through American Airlines

AA re-routed flight from HNL to LAX due to delay. My group of 3 with reserved seats in row 9 was broken up, with one assigned to a middle seat, another in the last row of the plane. Not happy. No explanation to the delay. No apologies. No compensation. Would have been nice to be offered an Admiral Club admission or a voucher for the extra 3 hours of layover in LAX. Could not hear the boarding gate announcements in LAX. Adjacent gate was boarding at the same time. Loud speakers were competing against each other. Barely made my boarding group.

Almost a 6 hour flight and the only food option is a cheese plate… and chips. Also how is it there are no options for texting on American. I’ll be going back to delta and united.

The chair cushions may need an upgrade. I have been noticing they are so worn out, thin so you’d sit in a dip 😄. Other than that, all was an enjoyable trip. Thanks AA!
