Long delay before boarding. By the time I was informed of the delay I was already at the gate.

Long delay before boarding. By the time I was informed of the delay I was already at the gate.

One of the worst check-in experiences ever. Apparently, we were overweight and had to completely repack. They tried to charge us an extra $35 per bag on top of the standard checked baggage fee we had already paid in advance. Surprisingly, we managed to fit everything into our carry-ons and stayed under their precious 50-pound limit. (By the way, 23 kg is actually 50.7 lbs, so we couldn’t even go slightly over 50 according to the very unfriendly agent.)

Tight legroom. The breakfast was provided, which was a plus, and okay the taste.

Awful. We got the last seats and they don't recline. We've been on this horrible journey since 6am and won't get to our destination almost a full day later. Oh and no food, either. Never again.

Self check in is not indicated well if you approach Terminal 1 from Terminal 2 Parking

Everything smooth (including the landing) and on time. Easy. Thanks.

My flight was canceled and rebooked about 3 times. Original flight had a 50 minute layover. Flight was canceled and rebooked with a five plus hour layover. I demanded refund

While the flight itself was pleasant, the process of checking in was difficult. The line was long and our connection time was but two hours. When we finally got to the Hawaiian agent and told him that we were traveling on Alaskan Airlines, he told us we would need to go to a different terminal. I told him that another Hawaiian Airlines agent had directed us to him. I’m looking at our tickets, he noticed that the Alaskan Airlines flight was to be managed by a second party. He ended admonish us for not telling us so Rather than considering that we might’ve been right in the first place.

Only problem my credit card had over three pending credit card charges for luggages. I hope these charges do not post. I have already contacted my credit card companies.

It was a very smooth fast flight, crew was prompt and comforting. Alaska airlines are the best.
