Agent could not provide me a boarding pass for the second leg of my flights - yet with a partner airline. Not understood.

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

Enforce the one bag rule for carry ons. Don't allow people to have 2 and 3 carry ons. Make baggage gets loaded onto the correct plane. My bag didn't get put onto my last flight so I didn't get it until the next day.

This was my second time flying Alaska Airline in the 1st Class cabin. Everything was fine with the exception of the food and entertainment. The food was just ok but not what I was expecting from 1st Class. A BBQ pork sandwich and baked potato. There wasnt any in-flight entertainment. I found that odd since it was a coast to coast flight Seattle to Dulles. My sister flew 1st Class on Delta on a shorter flight ( Seattle to Cincinnati) and had an awesome meal and in-flight entertainment. I typically fly Delta but there wasn’t a flight with times that fit my schedule. I am by no means a primary donna. But when my upgrade cost over $900…I didn’t use any reward miles…I was expecting more than what I got. I will never fly Alaska Airline 1st Class again. I will stick with Delta for all my travel needs whether it’s in 1st Class or coach.

Very easy, stress free airline. Was a wonderful experience. Will use again

This was my first trip with Alaska Airlines (round trip DCA to San Diego). Despite a slight delay on the return flight, I feel compelled to post a RAVE review! I cannot praise the airline and the crew enough! Everyone was kind, professional, and courteous, every step of the way- excellent service, snacks, and entertainment! On both legs of the trip I inquired whether there were any free seating upgrades and my request were granted BOTH times! I’ve flown on other airlines where they won’t do that, even when those premium seats are empty. As a customer service professional myself, I can say I left my experience feeling like a valued customer and not just a number. I NEVER expected to praise an airline lol I’ll definitely go out of my way to fly with Alaska on future trips. Thank you for such an awesome experience!

The seats were spacious and comfortable. Even in basic economy. However, the flight boarded 30 minutes late.

I think Alaska should start including free meals on these longer trips.

Departed on time and had an efficient boarding process. The inflight wifi was not working on one of the flights.

The flights were all late and they would not refund my money
