All pretty good except we were a bit late getting into Seattle and I had to run to my next gate and was the very last person to board (they were about to close the door but were terrific about getting me aboard.) Hustling between gates is not usually a problem, but I just had a hip replacement which affected my ability to hurry.

There isn't any food on that short flight. The plane had to be de-iced but it wasn't much dela

A review system on Kayak that would allow “NA” (Not Applicable) as an answer. For example, if food wasn’t ordered, I cannot say how good it might or might not have been.

Easy boarding, good staff, comfortable seats, easy ride. Also, friendly passengers!

I don't know what it is. But it seems that flights from Ontario to Seattle are always delayed. This one was delayed 3 hours. I guess I should just expect it from now on.

Your seats are too crowded! and you don't serve full meals on this 5 hour flight? Just rake in the profits.

FLL to SEA delayed one hour due to mechanical issue. Had to return to gate from runway.

I’m highly satisfied with Alaska over other airline experiences however the wifi kept kicking me off and the service was intermittent. I kept having to fool with it to get it to work.

As expected cyst service up front was very good we needed assistance at the gates and they were very accommodating

Indigo screens for passengers would have been nice but the free WiFi was nice
