It was a little chilly on the ride. The entertainment was the book I brought, and it was excellent.

The confusion from Alaskan Airlines to American, no one at the front desk of Alaskan told me I didn't have a flight, which made me miss my flight that was transferred over to American TERRIBLE customer service at Alaskan!! American Airlines was a great experience. Alaskan TERRIBLE!

I paid $49 to select my seat---6A a window seat just behind first class. When I started to get on the plane I was told that my seat had been given to someone else and I now had a middle seat. They finally gave me an aisle seat. When I told them I wanted my $49 back, I was told I would need to call alaska and fight with them to get my money back. And when i was on the flight people going by kept hitting me with their bags. I have tried calling alaska twice to talk about a refund but never got thru to the right person!

Easier to file a claim. My fiancé got the flu and we had to cancel. ive been given the run around filing a claim. Call me at 831.588.4346 with a live agent please

Small dirty plane for a 5 and1/2 hr flight. No food no entertainment

All 4 members of my family found the seats terribly uncomfortable. 2 of us suffered from back issues the next few days.

Plane had a maintenance problem two hours into the flight and we had to turn around. Alaska was nice to put us up in the Hilton in LAX but the cost of food in the city was WAY higher than our vouchers and the hotel had no continental breakfast. We ended up spending over $100 on food for our family in addition to the vouchers.

Check-in was easy, I did it from the app. Boarding was easy, the crew was great. Santa Barbara airport had a disabled plane so we had to land in Burbank to refuel. They kept us well informed, and everyone was great. A very entertaining person from the Burbank airport got on and told a few jokes.

I appreciate the priority for safety. I did not enjoy how the delays were handled.

Delays, delays, delays.... (and) Told no room for carry on after boarding B Group and told to drop off our carry on at door to be checked in instead. There was plenty of room left in the overheads above our seats right up to the end of boarding!!!!

The service and food needs to improve to catch up with other international flights

Would have been good to have a meal since it was a 5.5 hour flight

We boarded after several delays due to mechanical failure and a gate change. The seat cushion in the exit row was very compressed and offered no cushion, making the four-hour journey reasonably uncomfortable. The WiFi worked for a few people, but for most, it did not, and you cannot get entertainment unless you can connect—American Airlines flights do not have seatback screens, and you must use your mobile phone.

Timely boarding process, made up for lost time even after a lengthy wait for de-icing

AA is always pretty solid. Was on time all the way around today so can’t complain!

It would have been better if I could have had my flight on time. It was delayed for 5 hours. Caused me to not be able to fulfill my promise to my granddaughters. Other than that it was a good trip.

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

11h50m total delay. Had to switch to another flight that was still a 7h30m delay.

RE Food: Wish there was a choice for No Rating. Flew from Honolulu to Los Angeles on a Red-Eye flight (11:00 pm to 7:30 am). Other than a package of cookies with a beverage choice offered soon after take-off, and a beverage choice shortly before landing, no other food choices were offered. Everyone slept or rested for most of the trip. Nothing to rate. RE Entertainment: Everyone was sleeping most of the flight. Only saw one passenger watch about 30 minutes of entertainment on his iPad. I never attempted to access any entertainment options.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.
