They HOT tag your luggage if you have a connecting flight with a short layover, so any time you need to connect from Seattle on a subsequent flight just check to make sure your luggage is handled that way. While I was on board looking out the window, I saw my suitcase being loaded last - LIFO planning so that it would be unloaded first for my connection. Smooth sailing after that…. Great service!

Early Wednesday mornings must be the prime time to board because there was no time to stash my watch, etc. into my bag before security since there was almost NO line. Another bonus for morning people.
