I’m not quite at 6 months yet but FWIW, when I was hired people were speaking of getting lines at coastal bases right off OE on the 73. At the same time had a friend waiting almost 6 months (paid) for OE to begin on the 756. Presently, the left coast 73 bases are overstaffed for FOs and many are having trouble consolidating. I am closer to the G line on the 777 in SFO than I am in either of the left coast 737 bases, and those junior 777 lines are about the same for commutability and days off as the junior 737 lines. Global vs basic reserve is a consideration…but not for a lineholder…
Point being times are weird and anything you hear now probably won’t still be true in 3-4 months.
