Don’t fly with Alaska if you have a layover in Seattle. Guaranteed to screw you over. We waited at terminal S3 &were >2 hours delayed(mechanical issues)and told to change terminals to a different plane that required riding 3 shuttles to get to new terminal N14. Then they delayed the flight even further and changed gates again. when I went to the customer service in terminal N, the manager turned me away without apologizing & refused to assist me but mandated I leave her alone as her shift is nearly finished and insisted I totake another 2 shuttles to terminal C so I can just talk to another service rep while dragging my family of 4/ kids in tow.

Everything was good. Please have a wheat free option for snacks in the future.

Not delay for a few passengers. That was uncalled for. If idiots can't make the flight on time thats their fault. Why should I be punished for them? No more holding the plane for one or two people

How can I review what was denied to me. Instead of offering to let me pay for the ticket I got booted of my flight with no way home and no choice but to purchase another ticket for 12 hours later. Filing a complaint with the DOT

I like them since I live in Alaska and I don't have much choice

Flight was delayed about 40 minutes by a mechanical problem. This made a long day even longer. Otherwise good.

After we boarded there was quite a long time before we actually took off, and there were no announcements from crew about why we were delayed. Later when they did make announcements they were largely inaudible. There was no food (other than for purchase) on the flight and no entertainment. Thats not a complaint, just explaining my ratings in those categories. The flight was smooth. Baggage claim was rapid.

We were flying 1st class for a special occasion. This was a Hawaiian airlines flight. It was exceptional. Very comfortable seats and space. Extremely attentive crew. Food was great for airline food. They provided tablets to watch and full headphones to listen. This was the best airline experience I have had in decades.

you could have gotten me there on the day I was supposed to be there, not a day later. Paid for 3 nights at a VRBO and got to spend only 2 nights there.

I requested wheelchair assistance in Seattle transferring gates and in Anchorage to get to baggage claim. No assistance was provided at all.
