Overall good. Good communication from the captain on delay, cozy seats, nice staff, and a perfect landing.

The plane was clean. The flight crew was friendly and helpful. The flight was smooth and the pilots kept everyone informed of our status, etc. It was my first flight on Alaska Airlines and it was great. I'll be choosing them again in the future.

Good but a boarding pass for my return flight was not sent to me.

I really wish there were TV monitors. I don’t have a mastery of computers, so I was left with a six hour flight, and no entertainment.

Good flight and crew. Wonderful to be on time! Only drawback, I didn’t know ahead of time there was no back-of-the-seat tv screen.

Everything was fine. There was just quite a bit of turbulence, which always makes me very anxious.

On my trip from Seattle to San Jose it would’ve been nice to have the gate transfer nearby instead of at the opposite end of the airport that’s it

This was our fist time flying Alaska Airlines. Overall it was a great experience. Ticket counter, gate agents and flight attendants were all wonderful. They all seemed happy at what they do and it shows. Of 4 legs, the onboard WiFi was spotty on 1 leg. The food in first class cabin was ok. Couldn’t get the text messaging notifications to work so had to rely on Flight Aware and the Alaska App. Flights were on time and uneventful. We would def fly Alaska Airlines again :)

Both flights were delayed, the Bellingham to Seattle flight was delayed so much I nearly missed my connection with a two hour layover to spare. I could have driven to Seattle and back in the amount of time the flight was delayed. Seattle to Bellingham Washington also delayed. Not good.

I've flown at least six times this past year. For some reason, the entry into Seattle felt like the worst ever. It felt like the plane was going too high, too fast for entry and then a very rough landing. Could have been the weather. All else was fine. Please consider changing snacks from pretzel sticks to nuts as an option.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

The seats are uncomfortable, feels like a small seat pad on plywood.

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

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.

I notice that every time I fly delta or any American carrier, the staff seem tired, overworked, and not at the service level I’m accustomed to in Asia. They frequently crash into my arm when coming down the aisle. Food is shoved at my face with no greeting or verbal cue. The food portions seemed much smaller than usual and didn’t see much wine or beverage options. This is comfort plus? The plane was old and tired. The bathroom was dripping with mineral stains after a long lack of cleaning. The power socket did not work, although the USB output did. I really wonder why I’m flying Delta, I think it’s time to switch to ANA.

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

Screen didn’t play movies, do I was pretty boated the entire flight.

It was very cold because the air conditioner was on high power, and my son got sick.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

Delta is one of the best airlines I have flown
