We received a check-in reminder the day before the flight, and it listed the flight at a later time. Correct flight number, same seats, etc. for 3 hours later. I called the airline to confirm and they had no record of the email. The info was wrong, and we would have missed our flight if we'd assumed it was correct. I want to know where/how we received this incorrect info.

Middle seat, elbow wars. I cannot understand why they load the front of the plane first. You would think it would be more efficient to load the back to the front. I believe it is. And it needs to be changed.

Paid extra $230 to check frozen fish on arrival to LAX. I was told my bags miss my flight and we’re gonna be on the next flight that comes in two hours later regrettably my family was here to pick me up so I had to drive all the way home to drop them off then turn around and come back if I had waited on Alaska to deliver them they told me that they would be delivered in 4 to 6 hours after 8 AM tomorrow which would’ve caused the fish to spoil stink and be a lost cause they would’ve put about $2500 worth of fish down the drain very unhappy with Alaska Airlines for not getting my baggage here, especially since I had to pay for the extra service

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.
