Flight attendants made this flight wonderful. They made sure everyone had what they needed and anticipated future needs. They made adjustments as needed. It was clear this was an experienced crew.

Very delayed for seemingly no reason. Made me miss an event

we bought Mediterranean boxes for lunch. The salami in mine had gone bad long ago, but my partner had good salami and could eat it. Could I buy assigned seats? I guess that I didn't spend enough, so sat at the back of the plane

the flight attendant was so great and the upgrade to first class was top notch

There was no food or entertainment, thus thus the neutral rating.

The Alaska Airlines app made it very difficult to find my boarding pass. It was very frustrating to use! The flight itself was flawless.

No communication with delayed and canceled flights. Completely in the dark for the whole experience.

You need categories to denote when food and entertainment are not available.

Alaska is generally the airline I fly nearly all the time. I nearly always have wonderful experiences on Alaska and never a complaint. However, this entire flight felt like we were in the cheap seats the entire time and I had even upgraded to a cushier seat. For an over six hour flight (that became 7 hours) there was no online entertainment. I couldn’t connect to Wi-Fi and we were offered one snack and one drink. We were instructed to go to a particular baggage claim and 30 minutes later our bag still hadn’t come out and it turned out it was the wrong carousel announced. So overall, this flight was a series of mishaps really less than mediocre service even though flight attendants were wonderful.

Alaska is a great airline. Unfortunately, our flight was canceled in a really late hour and it caused a lot of hardship in my travel process.

I didn't take this flight. I changed the flight. Why am I getting surveys and notifications on flights that I change. Seems like a defect with Kayak.

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.

Timing, quality of service, promptness and courtesy of the staff

It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

delta last minute gave me a boarding pass for a different flight with no confirmation that they were changing it

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!!!!

Excellent flight and got us around tough weather. Only issue was seat TV did not work and crew tried to reboot.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

was sitting in the jet bridge for 10 minutes in -20 degree weather waiting for my bag

Outdated equipment in disrepair, wifi inoperable. Broken seats, taped air vents, generally poor condition, the 717 showed its age and lack of upkeep.
