On time boarding, plenty of overhead baggage space even for Group F, on time departure / arrival.

The AC was running on the plane when its 40 degrees outside

We were seated in the middle of a large group of noisy 8th graders

Short flight so really no interaction with crew and there was no food. It was on time and comfortable. Liked the plugs in seat in front!

SeaTac was a mess first class check-in not clearly identified Temporary signage needed since only one door into Alaska check-in area directed you to coach baggage check.

Boarding was done really poorly. I understand the flight was late but even when the plane arrived they just stood around and didn't streamline the boarding process.

We could not find a parking spot in the garage so we left airport to find a parking lot. We were late and afraid we would miss our flight. We were greeted at the new Alaska check in and I was really upset. She got two people to put us in wheelchairs and we flew through the airport and security. Then all the way to the N gate and on to the plane. Somehow they hadn’t taken off. These two individuals deserve a medal for getting us to our flight and onto the plane. It all started with the wonderful greeter at check in. I wish we’d gotten her name and the two who got us there.

When I made my transfer from my flight from Missoula to Seattle to Seattle to San Jose, the gate was at the opposite end of the airport, which I thought was inconvenient since there were so many gates for Alaska right where I landed that everything was good

I was traveling with my parents to San Francisco. One of front counter employees saw my parents are senior, he let us boarding first which was so thoughtful.

The food was good but needed more taste, or it would have been better if the airline had provided salt and pepper.

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.

For coast to coast travel the A321 and even the NEO, even in first class will never be excellent. That would take a B787 or 777 to accomplish.

The flight crew was fantastic! Which the seats had a small TV.

The foot ottoman cushion was missing on my business class seat.. the hydraulics is on its last leg & seat cushions do not have support or paddling. Heavily dented by butts

also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!

I was unhappy with having the seat I chose changed at the last minute. I was moved to an aisle seat which did not recline and was next to the bathroom. The bathroom odors made the flight entirely unpleasant. Having carefully chosen my seat months before I was not pleased with my AA experience. In addition, they ran out of tea during flight service, really?

Dallas Hub. American taking ownership for their screwups instead of blaming their contractors and customers, trading their people, their call in service, reservation agents and their ticketing process. Make sure wheelchairs are available especially when the request is in their record.
