The most junior upgrade on the last bid was 13 years at AS. You can die mad about it. Or just understand that a lot of people put in for SEA captain and they didn't get it until they were 14-18 years in. One guy got SFO captain who was at 13. We also are not growing on the 737 side, we are in fact, reducing the fleet size. So there won't be an upgrade bid anytime soon. It's far more likely there will be a reduction bid.
At least
@Cherokee_Cruiser acknowledged there was a behavior change. Senior FOs are trying to upgrade and they can't. They will keep trying. Until they can upgrade the upgrades will go very senior. I'm pretty sure how lucky you were when it came to hiring and how lucky I was when it came to upgrade (or stupid). Those times are gone. They will never come back.
