Alaska changed their departure time 4 (!!!) times, then couldn't find my luggage from a direct flight from Spokane to Portland. There were 11 passengers who didn't get our luggage & had to wait 40 minutes for Alaska to find our luggage. Alaska should reimburse everyone their airfare for such inexcusable service.

Alaska changed their departure time 4 (!!!) times, then couldn't find my luggage from a direct flight from Spokane to Portland. There were 11 passengers who didn't get our luggage & had to wait 40 minutes for Alaska to find our luggage. Alaska should reimburse everyone their airfare for such inexcusable service.

The crew was great and everything went smoothly coming and going.

Flight was scheduled to leave at 6a and delayed for 5 hours due to “mechanical” issues. Everyone else on the flight received an email voucher for $24 of food for the delay, except for our group. Also the carry on luggage bins were full and the crew requested that everyone to pass their carry ons back up to the front while everyone was still standing. They gave no other direction and kept rushing the process. After all bags were sent up, they then asked for seat #s to go with each bag… They should have probably had everyone get to their sits and then pass the bags up in a controlled process.

In GEG I arrived at 0930 for a 1600 flight. Alaska had a rule that you could not check your bags until 4 hours before flight time. I was forced to sit in a chilly lobby for hours. I had access to a bathroom, but could not go into terminal for food and drink. Boarding and flight OK

Flight was smooth, but the overhead bins were not deep enough to stow bags vertically and we ran out of room - even with 8 passengers voluntarily gate-checking their bags.

Nobody’s fault but turbulence all the way meant no service and no access to the bathroom,

late, water or apple juice only, short on overhead every flight announced

The whole experience was the way flying should be. Great agents, great flight crew.

The TSA line took over an hour and half to get through due to being understaffed and only having one scanner open. I got to my gate with five minutes to spare only to find out my flight left 8 minutes early. I needed help rebooking and had to pay to get a new ticket and was grounded for 24 hours. Not the greatest experience to start things off and had to completely rework my trip to accommodate the situation.

Flight was on time. Transfer was in same terminal. Flight attendants were very accommodating. .
