They cancelled the 6am flight around 12:30 AM the day before. I was luckily able to book through another airline. I called for a one way fare refund, the new flight is much more expensive. I lost $$$ in the difference and this caused lots of stress. I intend to take action following my trip, really off to a bad start and I will never fly Alaskan again

The gate agents begged us to check our carryons. They BEGGED us, over and over, and said that the flight was completely, totally full, and said that if we don't check our bags, it will cause huge delays. They finally said that "group suchandsuch will be required to check bags!" So I checked mine. Well, the flight wasn't close to being full, and many of the overhead compartments were *empty*! Moreover, my bag was delayed at the carousel, and it wasn't on the carousel that was posted. COME ON, AIRLINE, you can look at the seating for the flight on your computer and decide whether it's really necessary to beg and beg and beg people to go through the hassle of checking their bags! This is annoying as hell and makes me not want to use your crummy airline ever again.

My only complaint was how far it was from plane to baggage claim

SBP to PDX 2/17/2026. One person ahead of us at the counter. One ahead of is at TSA. First to board. First row, first class. First to be served. Food and service very good. First off the aircraft. Flight was nice other than some moderately hard bumps on climb out (please find a way to control that!). Air Force landing (none of that Navy slam you to the deck stuff). Wheel chair at the bottom of the ramp waiting for my wife. Luggage out quickly, walked right up to the parking shuttle bus. First stop on the bus. I like the EMB 175 aircraft. This was as close to a perfect flight as I will ever see. Bravo!

They changed our flight from a one stop 3 hour layover to a non-stop. Saved us hours and got us there sooner.

Departing flight to San Diego was delayed. Return flight from SD to SBP was delayed. Not terrible but not ideal

The flight was delayed for an hour, while we sat in the plane.

Flight was initially delayed 1 hour, but said come to gate at scheduled time in case plane shows early. Then the flight was delayed several times over for a total of 3.5 hrs for 1.5hr flight. The only compensation was $12 to get a water and some chips. Cant seem to fly anymore without some issue.

No prob with entertainment-would have selected n/a if it had been an option. No entertainment-flight was only a short hop. Great flight,

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

This was an auto-rebook due to being delayed from an earlier UA connecting flight. The boarding was fine, but they sat me in a middle seat when my original booking was a window seat. Overall, the flight was fine as it still got me to my final destination.

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

leg space better than expected. two washrooms for one plane isn't enough.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.

Flight crew and pilots did great. Flight way delayed due to a part needing replacement. Based on what the pilot indicated- the maintenance crew could’ve resolved this more efficiently than replacing whole part- and taken less time

Boarding took a long time for a couple of flights. We arrived at our final destination an hour late. Others missed their connecting flight. We had no time to eat between flights. My checked in bag was delayed because it was in another flight. At least they gave us a voucher because of that. The staff was very kind.
