I was very pleased with this trip from Anchorage to Seattle and Seattle to Billings. Wheelchair assistance was rendered and gratefully accepted. Unlike my outbound flights to Seattle I did not have long, painful walks on a bad knee to get to airport gates. My thanks to the Alaska staff.

I was very pleased with this trip from Anchorage to Seattle and Seattle to Billings. Wheelchair assistance was rendered and gratefully accepted. Unlike my outbound flights to Seattle I did not have long, painful walks on a bad knee to get to airport gates. My thanks to the Alaska staff.

No issues at all other than the seats. Of all the airlines I've flown on in my life (this was my first with Alaska Airlines), these were significantly the most uncomfortable seats I've had - more so than Spirit Airlines. I'm a relatively young guy and mostly fit but oof, i was aching in muscles I didn't even know I had. Not sure if the seats are standard for the plane (if it even works like that) or if the choice to use cardboard as cushion and 90 degree angle back rests was a decision, but it wouldn't honestly make me think twice about flying with them again. Other than that - perfect flight. It was quick, crew was nice, ride was smooth so all things considered I appreciate the last minute availability offered after a sudden relocation on my part.

Short flight was fine, but no entertainment and bathrooms broken.

All went smoothly. Only one delay departing Seattle of around 30 minutes.

We were in 1st class. Haven’t flown 1st class in over 35 years. This was special trip. 30yr anniversary and family travel. Food was good for airline food. Crew was very attentive.i expected easier movie access. Had to use own device. Second leg with Hawaiian airlines was exceptional in every way.

I paid for a window seat and on both flights I was put in the middle seat. Then on my flight to seattle I had to sit next to a passenger with a cat. I'm allergic to cats. So I sneezed, and had a running nose all flight.

Since the flight was delayed, snacks and water were provided.

Would have been nice if my flight was on time and I didn't miss my connection and had to spend the night in Seattle, losing one night at the VRBO I paid for in Sitka. And, my connecting flight was still at the gate when my flight was taxiing to it's gate. But, it took off. Too bad for me. I really can't believe you even want me to review or comment on my experience.

Upon arrival I was disappointed that the assist I requested to get to the baggage claim wasn't provided. The entire baggage area was not clearly marked and I wanted to store my baggage overnight, that wasn't available. I had to take it on the shuttle to the hotel!

The staff was extremely pleasant, and the ride was uneventful… If I were going to a place they serviced, I would take Alaska again
