The crew was great and everything went smoothly coming and going.

Had to buy a snack box as I am gluten free. They should be free in extra comfort. Food they provided was awful. Not enough water stops.

You can standby to get on earlier flight if the seat is open.

it was good except the too big men in my personal space.

Free WiFi was awesome. I hate the five hour delayed take off.. arrrgh!

I wasn’t aware that we needed to supply our own screens for entertainment

No outlets, plugs, way to charge the phone or service and no food on one leg o the trip, but other than that, great. Loved WIFI, the flight, the crew, the pilots, the schedule, etc. Great job. My new favorite airline!

Overall, we had a very good experience with Alaska Airlines on our flight from Honolulu to Seattle. The First Class cabin was comfortable, boarding was smooth, and the crew was friendly and attentive. The meal service was solid and the overall flight felt well organized. One thing that stood out negatively was the drink service. I was in First Class and, while quietly watching movies and not causing any issues, I was cut off after four drinks. I understand safety policies, but the cutoff felt a bit premature given the context.

Cancelled the flight cuz they sent the WRONG plane and then they promised to rebook us and let us know within the hour what our next flight was. I have heard nothing after 12 hours and can’t get ahold of anyone.

Wonderful as always! Pleasant staff, smooth ride, and timely departure.
