I see your QOL dilemna...SD vs. DC

Another option for you might be a regional airline, assuming your finances can handle it. Your seniority will progress MUCH faster at a regional so you won't be siitting hot reserve at 0400 on Dec 25th on the other side of the country. I know of a couple of 30 year-retirees who do that. If there's a decent regional in a town where you want to live it might be worth looking into. (You'd probably feel like babysitter at times). My personal threshold of pain for starting over at a major airline is about age 45.

There's also charter, 91, and fractionals. Currency and who you know are larger factors there, but 4000 hours in a hornet could open up some doors. There several operators at CRQ, and if you ask around MYF you might dig something up.
