Nothing! I just didn't eat or use entertainment. I had three seats all to myself and it was wonderful!!!!

My flight was delayed. But it was during holidays so you kind of expect things like that to happen. I am not a frequently flyer so I am OK with that. But none the less, once the flight started, it seemed to me like it went fast. 😊

The app is very bugy, did not work well. Other than that it was ok.

The flight was delayed an hour and it was not disclosed to the passengers until it was time to board. There was no in-flight WiFI available and such poor communication overall. Unfortunate that I was going to miss my connecting flight with poor communication on alternatives.

Flight was delayed because overhead bin didn’t close. The most insanely stupid thing I’ve ever heard.

Interline connection was terrible. Boarding pass from American didn’t work even though it was valid. Gate agent not present to straighten out the mess until the next to the last boarding group was called.

The steward on my flight went above and beyond in hospitality. So friendly and helpful. If I could give him more stars I would. I was so impressed I plan to use Alaska whenever possible and will praise highly to family and friends. (Ive already told my daughter and I’n-laws)

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

I don't know what it is. But it seems that flights from Ontario to Seattle are always delayed. This one was delayed 3 hours. I guess I should just expect it from now on.

Lovely crew and organized. Flight landed early, even better. Seats could have been endowed with more like Room.

Flight left early and arrived early. the whole trip was excellent.

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

Delta was great the entertainment was outdated.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

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

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.
