Worst travel day of my life. First bumped from our 7am flight—that we booked to ensure enough time to get to Chicago and get ready to go to a concert. Ended up on a flight 5hours later only to arrive in Chicago and spend 2 hours sitting in the tarmac. Missed the concert ($650 in tickets) and was too late to cancel the hotel ($500). I did receive a $200 voucher for the next Alaska ticket—soooo generous 👎. Would LOVE if Alaska reimbursed the $1000+that I am out!

I did receive a $200 voucher for the next Alaska ticket—soooo generous 👎. Would LOVE if Alaska reimbursed the $1000+that I am out!

Clean plane, friendly crew, on time and relatively easy boarding. We did have to switch departure gates in Portland, but got enough notice that it wasn't a big hassle. Only wish Alaska offered more flights from Kansas City.

The aircraft pumps heat into the cabin in warm weather. High, prolonged discomfort. Not okay to put customers through that. Time to upgrade their fleet.

I would love it if Alaska Airlines brought back the complimentary beverage service on short flights

the flight was fine, But I paid extra for an Aisle seat both planes and did not get what I paid for when you pay an extra almost $80 and do not get the desired seats it was frustrating I don't fly much because of my legs need more room. thank you for your attention to this

I paid for the $8 WiFi for the flight and it never worked. The crew told me it goes in and out and to keep trying. I didn’t get to watch the show I had planned to watch, bummer that I paid for the service. The person next to me said she has never been successful with in flight WiFi.

The check in Process was a bit slow. The flight was smooth and comfortable,

Liberia airport was a disaster -- as we were pretty close, they shut the runway and we were diverted. San Jose wouldn't accept us so we had to go all the way to San Salvador and refuel and wait. Crew itself communicated as best they could.

The FA's were fabulous, attentive, cheery, take pride in their vocation. The check in process was fast, orderly, etc save weight adjusted seat changes which respected aisle, window preference. The plane seemed new, clean. No free included food, fee based food options were average, free beverage. Could not get the entertainment App to work on my device. It seems other passengers were having the same issue. All in all a pleasant, efficient, restful flight made memorable by a keen, efficient, professional and very nice group of flight attendants.

I’m surprised that there was no screens for an almost 6 hour flight! Alaska needs to step up in this department.

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.

I liked being upgraded to first class. The flight was a redeye, so I did sleep most of it.

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!!!
