Both flights were on time and without in-flight issues. Although we had to check our carry-on bags at the last minute (cabins were full, no more room), our bags were on the baggage carousel very quickly. (Happened both ways.) Staff was friendly. Boxed water tasted weird (a little like cardboard?) but not a huge deal. Overall good experience.

Someone rebooked my Alaska flight to a much later Delta flight. Now I am sitting at the Seattle airport after a long international flight and have to wait another 4 hours even though I would have been able to catch my initial flight

It was a very short flight so there really wasn’t any entertainment my. The little pretzels were good though and the cabin crew was awesome.

They were flexible and able to get me home a day earlier due to a family members illness. Flight was on time and great friendly crew.

I had a problem with my reservation and no one could help me understand what happened. I booked my flight months ago and received a confirmation email. In the confirmation email, it said that the flight would depart at 3:15 p.m. A few hours before the flight, I tried to go online and check in, and suddenly it said that the flight was leaving an hour earlier. I had to rush to get to the airport and almost didn't make it. No one could help me understand why this happened, and I'm really concerned that it might happen in the future. I would appreciate some support in this matter.

The snack pretzels have garlic. just use normal pretzels. Tomatoijuice instead of only bloody mary mix

I liked that the crew was friendly, we left and arrived at near scheduled times, plenty of on-board crew to handle the cabin service for the flight and I found the price of my airline ticket to be excellent!

Planes were on time. Pilot kept everyone updated. Crew was friendly and helpful

Awesome just like that we have a timeline flying Alaska.

Behind schedule. Lots of time on tarmac. Perhaps unavoidable. Better than crashing!!
