Great job Expedia and Alaskan air

The plan was hot

Food was average

I am a shorter person and had a 5 inch clearance between my knees and the seat in front of me. My seat mate was 5 ft. 8 or 9 inches. Her clearance looked to be about 2 inches. Can’t imagine what it must be like for someone over 6 ft. And the airlines really need to address seat size and the growing obesity epidemic in the US. It isn’t fair to squeeze people into seats and for others to have to share their seat space with someone too large to fit in their seat alone.

The service was great. The seats had enough legroom but as usual were too narrow.

I was 100% satisfied with the entire trip.

It would really speed up loading / unloading if the carry on rules were enforced. Just because you can carry it does not mean that it is a legal carry on. One per passenger plus a jacket.

One of the features I don’t care for on basic economy is that you can’t select your seat. You can’t even pay to upgrade.
