No negatives. Crew was great, flight was on time and there were no crazy passengers. 🤩

The crew was great and everything went smoothly coming and going.

No headphones provided. No gf food. Only 1 beverage cart run sAN to HNL. Rarely saw crew members

Everything was excellent. It always is with Alaska Airlines. Thank you. 😊

Flight was on time. Crew was helping & seat were comfortable.

The flight was good, but your car partner, Wisecars, was worse thane awful. They didn't have an agent nor had they inform me which car rental they were supposed to have issued a voucher.

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. 😊

Nobody’s fault but turbulence all the way meant no service and no access to the bathroom,

I appreciated that the two flights were on-time, smooth, and stress free.

Cheerful crew, arrived early, but did have to wait for a gate because of that. But it was a pleasant flight.

Delta is always late. Ruined our first day of a short vacation. Timing is important. We pay to stay on an itinerary

Seats were not bad enough and uncomfortable good legroom in the emergency exit row we were in, but we were forbidden to hold my grandson on my lap for a little while, and the stewardess passed us saying it was against regulations which makes little or no sense when you’re 36,000 feet. The food snacks were really bad. Tasteless tasted like wallpaper, but we’re supposed to be protein bars, and the announcements were all completely incoherent because of the noise of the airplane and the lowness and crackly nature of the PA system.. this was disgraceful. No one in our party could understand a word of what the captain or the flight attendant were saying —not a word! The landing was a little hairy in a pretty stiff crosswind -we bounced before the plane stabilized on the runway

Flight team was great and we even arrived ahead of plan!

First The flight got delayed because one of the crew members was late and we couldn’t board until she arrived. Then we all boarded and got held in the tarmac for another 30 min.

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Crew was absolutely fantastic and we’re so welcoming and friendly ❤️

It was as good as it could be. Flying is not a pleasant experience these days.

Very good flight. Crew was great. No issues and we even arrived early.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Having to up charge for a seat assignment is not good. Delta can do better
