The DALPA roadshow presentation “RJ fleet count Comparison” slide notes that (old) UAL has “unlimited 70 seat jets and 78 seat turboprops, subject to block hour ratio.” Anybody know what their block hour ratio is, or how it works?

I’ve also seen it posted on this forum that the UAL 70 seat jets are currently capped at 124 or so – but I’ve never heard anything about them being capped. Anybody know if that’s true?
