That is far enough in the future that I wouldn't worry about it at all. SFO was most junior because it was "growing" and it's very expensive to live there... as with most Alaska bases. Nothing too shocking if you live in Hawaii, but real estate near SFO is ridiculous. Alaska also typically attracts people that want to live in the Pacific Northwest, and so they have a lot of turnover and movement when trying to grow other bases/cities.. it was ANC when I got on property, then for years LAX was junior, now SFO. SEA always has a relatively junior seniority too, so that is usually an option pretty quickly for new hires who don't want to be SFO... unless we stop hiring and don't put out new bids.
