Staff was great. Flight was cramped, and flight to Spokane was delayed.

I would fly again. My trip from Newark to Seattle had a 3 hr delay. Disappointed.

It was a very smooth fast flight, crew was prompt and comforting. Alaska airlines are the best.

The flight itself was okay, but there were 2 screaming kids in front of me my entire flight which made it just awful. The parent did zero to try and make the children settle down and flight attendants did nothing either. I understand it's hard to travel with children, but constantly yelling, screaming, or loud talking for 4 hours straight is just ridiculous.

There was an issue with water that led to us not having potable water onboard. They dumped the onboard water and we were two hours late taking off.

All good. Great food and entertainment when there isn’t any on a one hour flight

Boarding for Alaska Airlines is always chaotic with many people crowding the gates. Arriving in on Alaska in Los Angeles is always interesting since there is never a gate available. So the planes are often parked all the way out on the west side of the airport while waiting for the gate to be cleared of the departing plane. This flight was no exception.

Flight was delayed about 45 min and they never offered an explanation. Peruse, staff were friendly and competent and the flight was safe.

It was a really smooth flight. I hate heights. All made it feel smooth. Thankyou

No TSA pre check on boarding passes. Was told known traveler numbers are only kept with Alaska Airlines mileage plan members. Did not notice until reached the head of line, and then was sent back through the line to general boarding which took almost an hour. Learned two things: check our boarding passes, which we haven’t had to do with our other airlines, and don’t fly Alaska! You used to be much better!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

Although the flight left late, we arrived early. It was one of the quickest boarding and off boarding experiences I’ve had. It was kind of annoying the only drinks they had were water, coffee, and tea. The flight was very smooth, temperature was just right, and flight attendants were friendly.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Kind staff. Snacks are small but that’s the new normal.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

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

Seats were really tight and the seat belts did not give enough slack.
