Airline reviews

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.

Yall need to integrate your system with Alaska more efficiently. They booted me off the first flight because of a discrepancy on your end.

Unfortunately, I was put into the middle seat in the first row of premium seating. Sounds nice right? No! that is the worst seat in the plane. I wish I was in economy rather than be in that seat! There is no seat back pocket, no tray table, no charger. Nothing! so unless you're row mates are willing to let you share their basic amenities any flyer should have, you are stuck. It was the worst experience ever! And the flight attendant forgot to take my drink order. I felt like the forgotten flyer.

Delayed and cancelled flights were hard and very stressful, both ways!

The flight was CANCELED!!! Can’t get much more “poor” than that. I had to switch to American Airlines, add another layover and got home in Honolulu 4 hours later than I was supposed to be home. One bright spot was Josh with Alaska Airlines at SFO. He got me on a United Flight that got me home a few hours before I would have. Without him I would have gotten home almost 7 hours after my originally scheduled flight.

It was pretty good except there was no food, which was understandable because it was a short flight but I would have liked to at least have a snack; otherwise it was great. Staff/crew, great. Thank you

Everything was good for the price I paid. Crew was very nice.

I was put in seat 6B with no warning. Had no seat in front of me just sticks out in the aisle so I had to hold what I could and put the rest in a bin way further down.

I was booked thru Hawaiian Airlines (HA) on Kayak in February. I got 2 confirmation emails from Hawaiian Airlines in February. Even though the flight ticket informed me the flight was marketed thru HA and operated by Alaska Airlines (AA), I was never given any confirmation codes or anything from Kayak or AA to check into my flight online ahead of time. They also couldn't find the HA flight number I was given on their website and was told my flight did not exist unless I searched thru the AA website for flight details that was similar to the info HA gave me. The only way to check into my flight and make sure the flight still existed required me to get there 4 hours early. When I arrived at the airport, HA desk told me to go to AA desk. First AA desk redirected me to another desk, second AA desk told me to find someone with an iPad, and finally the iPad rep was able to help me. I also had to chat with AA reps online the night previous to my return trip because the same issue occurred.

There were several delays and we were stressed about making our connection. The announcements for boarding were hard to hear or understand. The seating was uncomfortable for a 6 hour flight.

Maria and her partner In SLO are phenomal! Great customer service!

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

Never happened, because of the first delayed flight I lost the connection and had to wait overnight and take two flights to reach my destination.

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.
