I had a meet-n-greet with Envoy at TPNx last weekend and the conversation included this very topic. My military experience is predominantly single-seat jets, but my resume also includes one brief experience in a multi-crew/multi-engine aircraft (C-12 = KingAir). He specifically asked if that time was PIC (aircraft commander, not Part 61 "PIC") so he could count it toward the 121.436 clause. It was all SIC, so no-joy.

But he still invited me back to interview the next day, so maybe they anticipate resuming FO hiring soon...?
