Thicker seat cushion would be nice. My butt hurt the whole flight.

All good! No entertainment on this new plane yet but ok for this short flight. Great on time flight! Thanks

No non-alcoholic drinks available except water and small apple juice cans.

The flight was delayed over two and a half hours thus causing me to miss my best friend’s funeral. All because the flight crew had to get more rest. That was the reason stated. I understand however very unfortunate. Glad everyone is well rested and resting in peace.

All good except both the outbound and return flights were delayed about 1 1/2 hrs.

Not great. My flight was canceled due to a mechanical problem and I could not get rebooked for the same day. I needed to get to my destination yesterday, not today. I was able to book with another airline but it was a layover and ultimately a 1 hour flight took me 12 hours. Normally I like Alaska much more than Southwest, but Southwest came through with a not terrible price for same day.

The plane was late arriving. The Alaska people did a great job of turning it around quickly and getting us off. We took off about 35 minutes after it reached the gate.

I liked the flight attendant named Tyler. He was charismatic and genuine. I like the pilot in my second flight, he was considerate to everyone’s feelings. I liked the people I sat beside. I like the plane size. I like Alaska airlines

Flight delay was inconvenient and exhausting getting in at 1 am. However the crew and lounge was very comfortable.
