Soda cans were mini-size; snacks were teeny. Options for entertainment on trans-continent flights were bad - no seat screens and no way to support device (as seen on other airlines) so had to hold device in position. Just overall, not good (compared to United)

First time traveling with them and they were great leaving on time arriving on time very clean planes 😊

Offer snacks/meals for people with food sensitivities. HAVE TV SCREENS!

Great price on internet. I love that WiFi was so affordable. Got a lot done.

Ground staff at LAX was very helpful. The Alaska lounge food and service is better than most airport lounges. I think the Staff are well trained polite and actually seem happy to work there. Great service Thanks 🙏 Jjk

The flight was very very delayed and arrived much later than planned. There was no communication about why or when our arrival would be. I would expect better and open communication about the flight but there was none. Also just pretzels? How disappointing.

Sat on tarmac for 30 minutes despite staring at three empty gates, one of which we eventually pulled into

Great flight. No problems. Everett Airport was so easy to get into and out of. Great alternative to SeaTac. Alaska was excellent!

The process was professional and really informative. I personally did not find any issue with thr process from start to finish.

The messaging about the change in flight destination and options for getting to SFO was poor. There should have been frequent updates. When I spoke to the boarding agent moment before we were supposed to board, he was flippant and offered no help before the announcement was made that transportation would be arranged. It was as poor of an experience that I've ever had.

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

It was ok until we got to DC and I wanted to use my United Club pass and the snobbish receptionist said that they don’t take one pass. It took me everything itch of patience not to tell her off

Food choice was poor and we had to buy on board snacks.

We were offer chocolate cookies , not everyone eat chocolate. Thank you

Lost luggage again. Our second trip to Mykonos, and 2nd time no luggage.
