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

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!

The would have rated higher, but I asked for a cup of coffee twice and never got one. Later found the crew sitting in the back having a meal and visiting. Just saying.

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

Probably the worst 1st Class I have ever experienced. Sam, our flight attendant, was excellent. Other than that, everything from the Alaska Longe experience to the buggy app to the uncomfortable flight and uncommunicative agents were poor. The agent who booked us in forgot to mark TSA PreCheck on our boarding passes and we had to go back to get this done. They were a cut below every other airline we have experienced in just about every area.

my first time with Alaska Airlines, an exceptional airline with great employees.

The plane was late arriving at the airport which in turn we left late. I had to literally run to my next gate to catch my connecting flight and my luggage did not show up at my final destination.

Seattle flight to Walla Walla has a confusing doorway system . Small signs once you leave gate area to tarmac. Almost went the wrong way to my plane.

Please don't shrink the seat space any more, as United has done. Thanks for all your good work.

The flight was delayed almost an hour causing many passengers to be at jeopardy of missing their connecting flights. There was no help in providing passengers help with connections or allowing passengers with connecting flights to exit the plane in an expediated manner.
