I'd guess 6 months, here's my reasoning: I went from 4 from the bottom of the ORD FO list on 3/1 when I got displaced there, to long call reserve on 5/1. There aren't very many long call reserves, so if I hadn't quit I probably would be a relief line holder in June. So maybe 4 months to hold a relief line, and maybe 2-3 more months to barely hold a real line? But it's all a wild ass guess.
