Wish there were more complimentary drinks available - only had water and apple juice. Also - no snacks were provided during the flight, but we were offered some items as we exited the plane.

Wish there were more complimentary drinks available - only had water and apple juice. Also - no snacks were provided during the flight, but we were offered some items as we exited the plane.

No negatives. Crew was great, flight was on time and there were no crazy passengers. 🤩

It might not have been their fault, but there was a two hour delay due to weather. Then we boarded and were about to leave when they said there were more problems at the destination, took us back to the gate where we had to fully deplane. But then five minutes later, they said everything was fine and to get back on the plane. This was the part that pissed everybody off.

The gate agents begged us to check our carryons. They BEGGED us, over and over, and said that the flight was completely, totally full, and said that if we don't check our bags, it will cause huge delays. They finally said that "group suchandsuch will be required to check bags!" So I checked mine. Well, the flight wasn't close to being full, and many of the overhead compartments were *empty*! Moreover, my bag was delayed at the carousel, and it wasn't on the carousel that was posted. COME ON, AIRLINE, you can look at the seating for the flight on your computer and decide whether it's really necessary to beg and beg and beg people to go through the hassle of checking their bags! This is annoying as hell and makes me not want to use your crummy airline ever again.

Flight got delayed like 5 times, then they put and ada passenger in the back of the plane.

They called me 2 hours before my original flight from SFO was to depart to let me know it was delayed and that I would miss my connection. They then rebooked on a different flight leaving a half hour earlier to a different connecting airport, so that I would not miss my connection. It all worked out and I arrived at my destination without a problem and 15 minutes earlier than the original flight would have. Nice!

Flight delayed no communication. The gate was changed so many times.

Comfortable seats, good drinks with lots of water refills, staff was kind and understanding of my disabled mother!

It is a hassle to not have entertainment screens on the backs of the seats.

I had to cancel my trip due to medical reasons. I have been unable to cancel online through either Kayak or Alaska Airlines.. I am trying to get my insured trip reimbursed by XCover. They are requiring a notice of cancellation or not using to get my refund. Please help me get that information. I have been unable to get this information from either Kayak or Alaska Airlines.
