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Delta was great the entertainment was outdated.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.

A regional sized plane was used for a cross country flight with no overhead bin space. I had to "pink check" my laptop and my medications. I was NOT pleased!!!!

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

boarding was uneventful. Snack was pathetic. A tiny fruit bar. Entertainment was limited to just select movies on your own tablet or phone. No live TV. I recently flew Jetblue and they had unlimited snacks and live satellite TV the entire flight. My seat was an exit seat, 20A. It was super uncomfortable. It felt cramped and the middle seat was taken up by a large woman who pushed into my shoulder and arm. Horrible flight.

They canceled our flight and left us stranded to figure it out

Cabin was pitch black, even during meal service. The reading lights for seat 2E/F did not work, and seat 2E did not recline.

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

Plane still had screens for watching movies. Good selection too.
