On time, good seats, not overly full, up beast positive crew.

Airport security lines in Seattle were awful. The only staff that was pleasant and made the trip more enjoyable was the young woman at the gate in Seattle. She was so pleasant and helpful. Flight attendant on the plane seemed like she would rather be anywhere but on that plane.

People were friendly. Flight was a little delayed. Maybe I missed the reason for it. Overall a nice experience.

Crews were friendly enough. To help the airline I checked my carry on baggage. Typical "gonna be a full flight we need 19 carry on bags to be checked to help out". So I helped out only to have to wait 30+ mins for my luggage and risked not getting to my car rental on time. The return flight was delayed. Kept hearing employees say something about "they didn't have any power" which is kind of concerning. The air flow and air conditioning was insufficient. It was warm and stuffy during the flight. Plus no free wi-fi......Booooooo!

Didn’t even get on, check my flight to Seattle for details. Do better Alaska.

A five hour nonstop flight traveling over a few time zones and over the dinner hour and you get a small bag of pretzels. And no screens to watch movies. I

The flight kept getting delayed due to a maintenance issue. That happens, but there is no excuse for changing the gate FIVE TIMES, including one time nearly all the way across SeaTac. After we were delayed for 3+ hours, they did send us (via email) a $12 meal voucher...except you can't find a $12 meal anywhere in that airport, unless you consider a bag of M&M's and a bottle of water a meal. The plane had one problem after another but finally took off 4.5 hours late. This caused us to miss our hotel shuttle at ORD (they didn't run past midnight and it was 3 am) so we had to wait 25 minutes and pay for an Uber. I did get a $50 flight voucher from Alaska...big deal. Barely covers my Uber ride that I shouldn't have needed.

I upgraded to a better seat and it was much more comfortable. Nobody serves food anymore and actually on a 2+ hr flight not necessary. I didn’t even get water.

Check in & bag drop was straightforward. Alaskair changed the gate approx 40 min before departure, and I only became aware due to Google wallet update to my boarding pass. Had to move from gate N1 to C9 which required use of the Train, luckily I had time available.

Very short leg - too short for any meals/snacks or entertainment.

Everyone was extremely friendly and nice, from the front desk to the cabin crew!

There was no food but a singular cookie for a flight that was over 5hours??? Yeah not fun I was starving and again super cramped plane and you guys need to get planes with screens too, WiFi is nice but common we need more

This airline would not refund my money and I had a physician note that I could not fly. They are crooks

I like that we landed safely and that my dog was safe underneath as well. Outside of that, we were 45 mins late for a direct flight that is 1.5 hours long. And 2 of my 3 bags did not make the flight. Only my dog was onboard.

Decent entertainment although my wife was not offered any ear buds so couldn’t enjoy. Real issue was the appalling food. Presentation was unacceptable with cheap hard to open packaged bread, plastic cheese again in hard to open shrink wrap, main course in small cardboard box again hard to open, wooden utensils which lack substance making the whole experience poor. Surprised I didn’t cover myself or neighbour as the food moved all over the place. Breakfast calzone was dry and unappealing with the staff basically throwing them around. Very disappointed

No pre boarding kiosk to check in, baggage claim detected luggage didn’t leave the airport, poorly managed recovery of lost luggage, and blame lost tag from conveyor to TSA/security, very poor from TSA/security check to delivery, crucial if compensation will go thru and will likely wait for months unlike United,

I didn't think about not having the right app for wifi because my connecting flight was with Westjet and when I took off from Seattle I was thinking I would use my wifi, but realized I couldn't on my Westjet app and I did not have Delta's app downloaded.

Plane seating was uncomfortable, very tight fitting for someone my height, did not recline and overall un enjoyable

No communication from Kayak or West Jet. Booked extra flights, flights cancelled, no one answers calls. Will be disputing charges.

Leg room is a problem the plane was dirty and there were no movies available on the app
