I don’t know is it exist on Boise airport, but Lufthansa and United are good and even for a huge distances like to travel between continents, they fly smoothly. Alaskan hurry up to come faster, but faster it can not be safer, you can experience all the shaking and suddenly blood pressure from going suddenly fast to high altitude and who have a heart problem or pregnancy put himself under a big risk flying with Alaskan airlines.

I paid to ship my carry on. Big mistake. There is never enough room in the overhead so everyone but me got their carry on shipped for free.

Keep an eye on boarding time. At SEATAC, if you are not sitting at your exact gate, you cannot hear boarding announcements.
