It was alright other than the changes in the Alaska Lounge. That and the migraine I had were disappointing. Other then that everything went well.

It was a short flight so no refreshments or entertainment which was fine.

The flight was delayed and then it was very short. The crew was nice. The seats weren't as comfortable on this particular craft.

Flying in both directions across country the gate designated on my boarding pass was wrong. From w to e across the country the passenger next to me coughed the entire way.

Although both planes (flights) had mechanical issue delaying both of my flights, the crew members handled everything with ease. Both flights had the smoothest take off and landing. I opted to upgrade my seat to first class and really lucked out getting the seat at the very front of the plane. Awesome treat to myself. I really enjoyed my flight.

The staff from check-in counter to the flight crew were great. Flight was right on schedule. 10/10

Changed flight from San Fran to Seattle Then with a Delayed takeoff barely made my connection Waited over an hour for luggage 😜

It was good. There was a mistake made in Seattle. Somehow we were bumped out of our seats as if we weren't on the flight anymore. The woman at the gate caught it and announced our name to come up and she fixed it.

I wouldn’t fly with Alaska again if you paid me.

I appreciated Alaska Airlines very much, they are expanding traveling locations globally as they partnered with another company and am excited and looking forward to our next traveling adventure with this great Airline. Thank you kindly
