Alaska pilots have no way to list for a jump seat either. First come first serve. Seniority does not apply. Alaska pilots, I think then Horizon pilots and then everyone else. CASS required and if you are given a seat in the back you are no longer a jump seater but you are traveling as a non rev courtesy of Alaska Airlines and are listed as such. Pilots/FA’s will have no indication otherwise. No need to wait to board or check in up front.
