First time flying on Alaska Airlines. Very good experience. Boarded, landed on time, baggage claim was quick just as they guarantee. When returning home, the nicest person at the check in counter helped with our checked luggage tickets and our wine cases, which were free to check (one per passenger) when you joined their rewards program. Will definitely use this airline again!

First time flying on Alaska Airlines. Very good experience. Boarded, landed on time, baggage claim was quick just as they guarantee.

We were really impressed with the customer service throughout Alaska Airlines. Every crew member we engaged with were very welcoming and eager to help. I find airline travel to be extremely stressful, but my experience with Alaska Airlines was the complete opposite. We will definitely be booking future flights with Alaska Airlines.

I paid a substantial additional fee to upgrade to Premium Class because I wanted a more comfortable, peaceful flight. Instead, Alaska seated a couple traveling with a 14-month-old lap child directly beside me. The child was loud throughout the flight—screaming, throwing objects, and tossing food around the row. What I paid extra to make relaxing and enjoyable became stressful, cramped, and absolutely miserable. There was nothing “premium” about the experience beyond a few additional inches of legroom. I understand that families and young children need to travel. However, Alaska sells Premium Class as an upgraded experience and charges passengers accordingly. If the airline is going to collect a significant premium for added comfort, it should give customers some meaningful way to protect that investment—whether through better seating options, advance notice, the ability to relocate when seats are available, or a refund when the experience is completely undermined. I would not pay for this upgrade again. It was a waste of money, and I intend to contact Alaska directly to request a refund of the Premium Class upgrade fee.

The seats felt an inch narrower and two inches closer than any seats I’ve ever sat in on a flight. It was just cramped and packed in. Otherwise it was fine. Just as expected from modern US air travel.

I cancelled this flight over a week ago, due to being in the hospital! Yet when I finally recovered and got out of the hospital I saw no one ever cancelled it and I was fully charged???

Liked direct flight options. Boarding is easy. Assigned seats, plenty of overhead bin space. Smooth flights, crew was helpful and friendly.

The staff's friendliness and helpfulness make a good impression.

I am truely disappointed in the delays. I have been flying Alaska Airlines for years and years and have always had the most amazing experiences. Not what has happened with being on time. Flying from SAN to PDX delayed. Then .PRX to SAN delayed,

Still seems like Alaska Airlines is not doing a very good job of anticipating the number of carry on’s going in the overhead bins. I was asked to check mine not to find out there was actually(surprisingly)enough room for my small luggage in the overhead bins. In the past, I’ve seen PLENTY of items in the overhead bins that should be underneath peoples seats.

It seems like most of the time theres no room for my allowed carry on bag. People are putting their things in the overhead compartment that belong under the seat in front of them. Getting tired of that!

We got stuck on the tarmac taxiing after landing early so we didn’t get off the plane until an hour later than we thought we would

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

Second flight in a row where the entertainment system is broken. 5 hour long flight with no entertainment and flight attendants did not seem interested in resolving the matter. Very shocked to be treated this poorly considering I paid for a first class experience and have Diamond Medallion status.

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

Easiest airport experience ever in my life at MSP with Delta check-in and flight attendant gave us a bottle of champagne in celebration of our 10-year wedding anniversary, so overall amazing!

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

The flight was great. The crew were a little terse about the size of my bag. It fit fine.

The flights were on time- Great service Would have liked more options for food choices.

The brakes on the A220 are sensitive and uncomfortably grabby

It was serviceable, nothing special but nothing awful on this leg.

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

Poor seating comfort, seat cushion too thin, very uncomfortable. My luggage didi not make the flight due to equipment change. At least. United had it delivered the next day. I was without my toilet items for one day.

Flight cancelled because of the grounded 737s. United was good about it and got us onto a later Alaska Airlines flight to Oakland (not San Francisco as originally intended). Had to go through security again and my wife dropped her MacBook Pro, which broke, a $2,500 whoopsie. But we made it home.

Luggage took too long go get off plane in Knoxville. Was almost 45 minutes after the flight landed.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.

The boarding was as always, the crew tried their best but not enough. The food was a disaster I had dietary restrictions that were half met because the company did not loaded the food for the flight. The entertainment screen was fine but content was not and also they removed the free messaging option from the flight and they charged 30 dollars for that crappy bandwidth. This flight is not worth the cost and the company is going down on quality.

As smooth as you can expect. Some issues with boarding because the previous plane took forever to deplane but overall, a good experience.

DFW-LHR Toilets not kept clean Too cramped. Aisles so narrow crew were constantly banging into people on the aisle seats. Even then, the carts used are reduced width. Other than that it was a decent flight on both legs

Excellent customer service at check in at Austin flight to DFW and excellent customer service from Karren in terminal B at DFW.

The flight itself was fine, but between the man in front of me putting his chair back, and the gentleman next to me who took up 50% of my seat, my back and neck are destroyed from the flight. I’m hoping for a better outcome flying back.

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

We were told there would be no food/beverage service due to turbulence. There was very little turbulence on the 2+ hour flight. I was in First Class and thought they could have done a quick service after take off as they had a quite bit of time before we would be reaching the predicted turbulent area. They could have at least passed out a quick bag of pretzels.

Very disappointed with the crew and the lack of attention given to the passengers. On a 5 hour flight they never offered a snack. One time offered a beverage and didn’t pick up the used cups until the flight was on final approach. The two flight attendants in our section mentioned that they were best friends and compared their pre flight shoes. When paying for first/business class there is a level of service that should be expected. These two spent the majority of the flight in their seats playing on their phones and laughing with each other. Very frustrating!!!
