I don’t think Alaska coordinates with Kayak. I did not get a “check-in” email inviting me to check in 24 hours in advance. Had to wait 20+ minutes to get a wheel chair.

Alaska Airlines has horrible customer service. After sitting in a packed airplane for over an hour, they decided to cancel our flight and had us deplane. Instead of helping us nearby, we had to ride two trains (in Seattle Airport), from the S-Gates to the C-Gates; only to stand in a line for 3 and a half hours. Throughout the 3 hours, there was often 1 agent at the customer service counter to help the passengers trying to get information and accommodation on a flight that they cancelled. Do better!

Poor, the last leg of our trip was cancelled and we didn't know about it until we arrived at the airport. Another flight on the same airline was not available until three days later which would have ruined our vacation. Luckily we were able to get re-blooked on another airline after spending hours at the airport.

I wish you would have just canceled the Saturday flight from sea to rdd on Dec 13. the diversion cost me more time and money than if I had just rebooked to Sacramento. It was a huge headache and cost.
