I liked the fast internet and twice serving of snacks and drinks. Paid food options could have included more.

I appreciated the ability to choose between multiple flights both into and out of Portland from Burbank on the same day, so we were able to attend an event and return without spending the night. I am unable to appreciate what Alaska Air calls "streamlining" the checkin/boarding process at Burbank Airport. If you have a smartphone and the Alaska Air app, it is probably fine, but removing the option of using onsite kiosks to print boarding passes does not meet my definition of "streamlined". I also found it challenging that both Portland and Burbank airports required the plane to sit on the runway for some time due to lack of an open gate at which to disembark. It would not be so bad if we could at least remove our seat belts and move a little bit while we waited, but that is not an option. I honestly don't know whether this is because of how Alaska Air operates, or just the circumstances of the particular day and airports we were using, but I normally do not experience these kinds of delays to reach a gate using Southwest Air.

I was not given a seat when I bought the ticket. I know airlines are trying to squeeze every penny out ot the customer, but we are buying a seat on the airplane, right? I find this irritating with all airlines, but especially Alaska because I fly it so often. No sense of customer use and loyalty.

It was adequate nothing special no entertain because flight was short. Crew pleasant.

All employees were very nice and I was very comfortable

Loved the gate agent and flight attendants. All were extremely helpful.

It was a good flight, wish they would have handed out snacks though.

Multiple delays and when we landed zero help getting to and making connecting flight.

There were no gluten free snacks and it wasn’t clear how to access entertainment.

Seat space Terrible. No real food on a 6 hour flight

Had a broken tray in business class. Crew just shrugged it off.

Everything was great except for the seat. The backrest would not stay in the upright position.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

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.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Mi primera conexión se retrasó por lo cual perdí mi segunda conexión la cual salió adelantada

Crew was not friendly when I went to request a seat change.

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

The flight crew was amazing. I’m very tall and they moved me to an exit row unsolicited!!! Amazing service.

I liked the cleanness in the bathroom and good crew on board and at boarding gates. There was no Hindi (Bollywood) movies. The entertainment can be improved as it is one of the worst one I saw when I compared it with other airlines. The Mumbai to Amsterdam flight did not have any food for my family which does not contain eggs in it though we have selected “Hindu Asian vegetarian meal”
