The second leg of my trip left without me despite being my inbound transfer only a few minutes late. My friends told the gate agent and they closed the doors and left early anyway. Then they tried to rebook me on a flight SIX hours later which only changed when I got a supervisor to make it 4 hours later. The gate agent was nasty, unhelpful, and walked away from me.

Worst part is being squashed in a seat ( I am not fat) and unable To get comfortable

Took forever to get on board. Flights was one hour late.

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.
