There was no seating at the gate, no where to charge your devices, super crowded. Boarding in group F meant all luggage space was taken when it was time for me to board. The boarding crew was short with everyone and seemed irritated. The luggage space was insufficient, the seat was too small for me (6'4") and very uncomfortable trip. I was in a middle seat between a person snoring the whole trip and a person with very strong body odor. The flight crew was terse and unfriendly, seemed irritated and impatient. Yelled a lot at people with earbuds in, understandable. Finally, we arrived 10 minutes early, only to sit on the tarmac for 20 minutes and wait for a gate. Worst flight experience I've had in years.

Check your emails that you sent me. 9 emails were sent telling me that my flight is Delayed. Each one with a different time 7:10, 7:55, 9:31, 9:09, 9:29, 9:44, 10:00, 9:49, and 10:10. That was how my experience went.

First time flying with any airline that has decent seating. Great experience crew was friendly and the pilot was as well.

The flight was delayed and then it was very short. The crew was nice. The seats weren't as comfortable on this particular craft.

Even though we checked in, checked bags, and went through security, I was told at the gate that I hadn’t checked in. I was pulled aside and had to verify my identity yet again. Otherwise, the flight was fine.

Didn’t like anything. Alaska boarding process takes too long and is poorly managed. Flight crew unorganized and too lax not very professional. I fly very frequently (weekly) and this as the worst overall trip I have ever taken.

Very nice staff, plane was delayed-they gave some snacks about 30 min after delay due to mechanical issues (which I appreciate them checking the plane)

Due to an aircraft maintenance issue we switched planes but the catering/food didn't make iot on the new plane. On the way home the in-flight entertainment/wifi was not available. Throughout these difficulties the staff and crew were fantastic to deal with!

The flight was canceled so i booked another flight with Delta, so essentially there was absolutely nothing that i enjoyed about my experience with this flight

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