I've always heard that 5 crews per plane is a well staffed situation for a regional.

We've probably all felt what 3.2 ish crews per plane feels like.

Historically I think my regional has aimed for high 3s to low 4s

Question 1: when we speak of these formulas, are we simply
looking at the seniority list total and dividing by number of a/c divided by 2 pilots, or do we only factor ACTIVE LINE PILOTS? I.e. no instructors, management pilots, LOAs, or anyone not on the bidding roster.

Question 2: Under 117 what will the new target be? Guesses to a range what will be considered barely sustainable, to borderline overstaffed?
