My boarding pass birthdate was printed incorrectly causing me to spend an extra hour in a check-in and then again TSA line and to miss a chance to have dinner pre-flight. My window seat was given away and was replaced with a middle seat. I would have liked an opportunity to charge my phone and take advantage of movies but many of the departure gate chargers weren’t operational and I don’t know of an in-flight charging option, The flight left 45 late after trouble with unruly passengers, and I was glad staff removed them.

Good - San Jose security is a breeze. Exact opposite of San Diego. Flight on time. Bad - FA's were not that cheery or polite. I thought we may blow out a tire as the pilot slammed down a hard landing in perfect conditions. He came in pretty hot like he had a date waiting.
I was seated at the back of the plane and the flight attendants were fantastic. I did not get food so can’t say. Thought the movie selection was lean.
the departure got delayed due to SJC situation, but it was a quite good waiting thanks to Alaska airline teams.
The flight attendant in the back of the plane was barely understood as she rushed through instructions to the point of being intelligible. She had a bored demeanor in her delivery.
Staff seemed genuinely nice, not just going through the motions.
The pretzels are awesome. The free movies are excellent. The plane crew was amazing. The Austin airport lounge was too small and overcrowded. There were not enough seats. And the boarding staff was not as friendly.
I like Alaska Air fine. Great crew. Late departure still arrived on time.
Excellent service and prices. I was not award of inflight entertainment.
They gave me a seat with extra leg room. But they didn't offer me anything to drink, just because it was an hour flight
There was a loud squeaky sound the whole time we were flying.
Had a broken tray in business class. Crew just shrugged it off.
I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX
Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.
Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.
Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.
Flight diverted in SD. Later take off in Seattle by 1.3hrs
Crew was not friendly when I went to request a seat change.
Really impressive staff at airport and on plane, especially given how busy it was
Was a great smooth flight from Detroit to San Diego.
