This was more with the third party booking through Kayak but my KTN for Pre-TSA, even though I entered it, wasn't assigned to my ticket when I got to the airport. I had to go through regular security. Also the Alaska app had trouble loading my ticket in the first place and I had to ask for it to be printed. Alaska Airlines was great but wanted you to know about this hiccup in the ticketing interface.

When I bought my tickets I up great my seats for extra $104 each seats 8A and 8B in the way back from Portland to Palm Springs they gave me the seats 15. I thought it was for round trip same seats . So I was very disappointed ☹️

Staff inside Portland terminal were rude, made us fell rushed and not at all accommodating to seniors. For this alone I will probably never booked from them again.

It was fine—the seats are not very comfortable and the aisles are very narrow. Nothing different from other airlines

Well the flight being delayed multiple time really was frustrating. But the crew and flight was good.

generally good. No snacks or drinks on the flight 3379 from Portland to San Jose, CA. Sad.

Everything except for the lack of a choice of the snack provided was great.

I like the friendliness of the staff. The food choices were OK. I wish there was more options. The entertainment through the movie portal was alright.

There was a very drunk man behind me who kept talking loudly to no one in particular. He was slurring his words and at times he didn’t know where we were going or whether or not we landed. He was also loudly using a lot of profanity. The attendants didn’t seem to notice or care and in fact continued to serve him alcohol. He was allowed to purchase 4 little bottles.

At the Portland airport, Alaska Airlines has put in a system where you have to create your own bag tag, then put your own suitcase onto a scale to weigh it. The day we were there, the system was not working properly, and we kept on being told to go onto different lines so it took us approximately 45 minutes to check our bag in. I do not work for the airlines why am I subjected to doing this? How all these companies are shifting their work onto people who have paid good money for their products is crazy. And then the system that the customers are supposed to use don't work properly..
