Overall the flight was on-time and plane ride very comfortable. The free snacks not so good - only a small bag of pretzels and no milk. I wanted milk. There was not entertainment on the plane unless I wanted to download their APP. But I would consider flying with them again and be more prepared on my part with food and entertainment.

This was more with the third party booking through Kayak but my KTN for Pre-TSA, even though I entered it, wasn't assigned to my ticket when I got to the airport. I had to go through regular security. Also the Alaska app had trouble loading my ticket in the first place and I had to ask for it to be printed. Alaska Airlines was great but wanted you to know about this hiccup in the ticketing interface.

this was the THIRD time in four Alaska flights that were 2 hours late. Only one was due to weather. The intentionally posted each flight as only 1 hour and 55 minutes late so that they wouldn't have to give out vouchers. And then the flights all ended up more than 2 hours late. Makes United look like a premium carrier.

It was fine, mostly I was just happy to be on my last leg home. No in flight entertainment but that's forgivable since it was only a 2 hour flight.

Flight was cancelled, then rebooked on a flight that I was unable to get through since they had closed the gate.

This was likely the smallest, oldest plane I've been on. It didn't handle turbulence well and we were all jostled a lot more than I'm used to. At least it was a short flight.

Flight was delayed two hours; for an hour and a half flight?! And so we missed our connecting flight to Rome because of the long walk between the terminals. Hoping to hear back from Alaska about some compensation for our missed flight and night stay in Los Angeles.

Boarding process was poorly handled by the gate crew and the onboard crew. No effort was made to provide equal treatment to passengers with overhead bin space. Crew seemed disengaged and unfriendly.

It was a good experience! Thank you:) No sparkling mineral water… 🥲

On time, WiFi worked, reasonable legroom, helpful staff. Unfortunately there was no water for handwashing in the rear lavatory.
