Airline reviews

This was my first trip with Alaska Airlines (round trip DCA to San Diego). Despite a slight delay on the return flight, I feel compelled to post a RAVE review! I cannot praise the airline and the crew enough! Everyone was kind, professional, and courteous, every step of the way- excellent service, snacks, and entertainment! On both legs of the trip I inquired whether there were any free seating upgrades and my request were granted BOTH times! I’ve flown on other airlines where they won’t do that, even when those premium seats are empty. As a customer service professional myself, I can say I left my experience feeling like a valued customer and not just a number. I NEVER expected to praise an airline lol I’ll definitely go out of my way to fly with Alaska on future trips. Thank you for such an awesome experience!

Our flight when we finally got rerouted to a different destination than we were going was fine. But 2 days was taken out of our vacation because our flit was cancelled. We understand mechanical problems and of course don’t want to be on a plane that has mechanical problems.Wish there had been another solution.

in-flight wifi was not working well. also the cabin temperature was a bit hot.

Nice crew, healthy snacks and drinks available. Flight to Seattle was short and comfortable.

had to be rerouted due to a medical emergency onboard. Alaska crew treated the patient with utmost respect and continued to keep the passengers updated the entire way through, which I appreciate. But it took 4 hours from landing until we were able to be airborne again, causing us to not get into SFO until ~2 am. I understand it was a tough situation for everyone, but that was an indecent wait.

The plane was dirty, the seats were tiny, wasnt my favorite airline tbh

I bought tickets MONTHS ago for a flight that left SAN at 14:30. That is what it says on our tickets. I was never notified of any time changes. During online check-in. I discovered the flight time had been changed to 15:45. This was unacceptable and had I been notified, I would have changed flights, or airlines. That departure time was unworkable with our plans. We called Alaska and asked for an explanation. They said flight time was changed 11/08/25. No proof of notification could be offered. We asked to be moved to an earlier flight. After much pleading, the rep said she would allow a “one time exception..” While I appreciate being moved, this was YOUR fault Alaska Airlines.

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!

Santa Rosa Airport is the best! Glad to have experienced it.

I love Alaska! We arrived on the later side without seat assignments only to find the had oversold the flight by 1. The attendants worked extra hard to find a way for our party of 7 to stay together and we made it on the flight! Loved the free WiFi also!

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

The crew, and fellow passengers, were super gracious and kind. There seemed to be plenty of bin space even though the plane was full. It’s nice to get a glass of wine with dinner in Premiere seating, and there was a lot of food.

Everything I mentioned earlier - the airbus was more comfortable indeed and the experience was further enhanced.

The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.

Awesome! On time flight, early arrival, and a complimentary upgrade!

It was nt delta. It was aeromexo. Service was awful. They served a very small drink and NO snack for a 3hr and 35min flight. Then for the first 30 min of the flight is was talk and talk over head interruption the movie/ show i picked to watch.

Delta One is extraordinary. I fly business when somebody hires me. I just wonder why there is such a chasm between business class and the insanely inhumane and nonsensical coach. The seats are not large enough to fit even my tiny wife. We fly 10% of what we did because we don’t want to pay 5-10 k but for $400 it’s unbearable. It seems like the accountants took over and made stupid decisions. Screw in 20 extra seats and make it so unbearable that people fly 90% less. Just put the damn price up and put some proper chairs in. But business, yay.

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

The flight was delayed for about 2 hrs. Other than it, it was good.

I am extremely disappointed that delta internal pilot manuals now refer to the Gulf of Mexico as the “gulf of America”. You can bow down to the Orange turd on your own. I will never fly delta again

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

Complimentary light meal would be appreciated. But great flight crew service on all legs

Flight delayed for more than 16 hrs and no effort was spent to provide an alternate

We had turbulence ever 1/2 hr or so and the captains announcements were SOOOO LOUD

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

it was a very short flight so my expectations were low.

Entertainment kept turning itself off. Gave up on watching a movie.

Very disappointing given gate agent behavior. Filed a formal complaint with United.

Crew was great (professional, attentive, prompt). Snacks for 4 hrs flight is deplorable.

Flight delayed. WiFi connectivity very poor if not existant. Last minute arrival forced me to run to catch my connection.

No pre boarding kiosk to check in, baggage claim detected luggage didn’t leave the airport, poorly managed recovery of lost luggage, and blame lost tag from conveyor to TSA/security, very poor from TSA/security check to delivery, crucial if compensation will go thru and will likely wait for months unlike United,

Flight was good, crew was excellent. No complaints at all

Delayed 3 times in a row for 4 hours total. Incrementally pushing back the flight claiming gate delays but they eventually changed the actual plane, due to technical issues. This strategy to avoid compensation to passengers is unprofessional.

Plane seating was uncomfortable, very tight fitting for someone my height, did not recline and overall un enjoyable

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

They lost my bag. Hopefully it will be here tomorrow.

No communication from Kayak or West Jet. Booked extra flights, flights cancelled, no one answers calls. Will be disputing charges.

The trip from LAX to Calgary was aboard a 737-700, which is more than twenty years old. Service was fine, and the food was good, but there was no inflight entertainment, and no WiFi. The flight from Calgary to Vancouver was also delayed more than an hour, due to congestion on the Calgary tarmac. And no food service, but there was in-flight WiFi which made a big difference.

Leg room is a problem the plane was dirty and there were no movies available on the app

The personal item sizer cannot take a standard backpack, and the cabin luggage sizer cannot take a standard carry-on. Designed for people from the island of Lilliput!!. and also compels people to pay additional fees to check their bags. Making money by ticking off the passengers is a very short-sighted business strategy, especially since they have a choice of carriers

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

Couldn't fit knees, only 1 toilet working, didn't get anything to drink cause the stewards were not able to get to us

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

The flight from SFO to YVR was delayed and my bag did not make it to my next flight from YVR to SYD. It took almost 3 days after I landed to get my bag and when I got it, it was filled with dust

Great check in process in LA and good service The check in process as well as at the gate is way better in the US versus canada 🇨🇦

All attendents were very efficient, pleasant and happy. Everything went smoothly. The seats could have been wider. There could have been more free food instead of just one small bar.

I liked a lot , the flight attendant so nice ,the seat very comfortable I enjoyed the flight , I will do it again with Air Canada,

It was a smooth flight both in the sky and landing!

The crew was really nice. The plane seats were kinda small even for a 5’6” / 158 lbs person.

Fare was great, seat comfort the opposite as cushion was worn out. Ok for 2 hour flight, not for 4.5 hour flight..
