Now that Southwest doesn't fly in and out of Bellingham Washington there are no good options to Seattle. You're best off driving or getting a shuttle, it's much more likely you'll get to Seattle near the time you think you will. Flying is just not a dependable option anymore.

They always change the schedule. My original flight got canceled. They put me up in the air flight. I had to stay seven hours in Seattle. That is bad.

They always change the schedule. My original flight got canceled. They put me up in the air flight. I had to stay seven hours in Seattle. That is bad.

I had a great travel experience with Alaska. The agents and cabin crew were all so pleasant and helpful. The plane was clean and comfortable. The connecting flights went smoothly even with some minor delays. All in all, it was nice not to be upset with the journey. I say that because over the last few years all my travel has been on Delta and American, and always involved cranky employees and flight issues. I wish Alaska flew everywhere I need to go. Will definitely fly Alaska every time I have a choice. Thanks for helping me look forward to traveling again.

Disappointed that there were no TV screens to watch a movie on the six hour flight. Disappointed that the plane did not have the right adapter to connect my phone and my iPad and charge them.

Ted. F/A in fist class did a great job! Very nice

The plane was freezing and no blanquets available unless you buy them. My screen was bad so I couldn’t watch any entertainment.

The flight attendants on this flight were fabulous! I flew with my two kids and it was their first flight ever. One attendant in particular learned it was my kids first flight so she took extra care of them. She brought them some wings and extra cookies which made the experience positive and memorable. Thank you so much!

Have I received a refund yet? They wouldn’t let me on the airplane it took hours. I lost my bag that told me what I needed to do to bring the dogs, and then they kept changing their minds.

Flying in both directions across country the gate designated on my boarding pass was wrong. From w to e across the country the passenger next to me coughed the entire way.

Even though we checked in, checked bags, and went through security, I was told at the gate that I hadn’t checked in. I was pulled aside and had to verify my identity yet again. Otherwise, the flight was fine.

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