I paid for an aisle seat and found I was bumped to the middle seat. No entertainment at all, bathroom was so tiny, a woman had a hard time in there. Seems it was considered for men only. This was my first time on Alaska airlines. I don’t think I want to fly on Alaska Airlines again.

I paid for an aisle seat and found I was bumped to the middle seat. No entertainment at all, bathroom was so tiny, a woman had a hard time in there. Seems it was considered for men only. This was my first time on Alaska airlines. I don’t think I want to fly on Alaska Airlines again.
