Hey Probe
Just want to make sure I understand correctly your point. Total block hours for United (mainline and regional) will remain mostly flat. Which I agree with you on that point.
However the upgauging is moving flying from large regional jets to small mainline aircraft. This would increase mainline block hours while decreases regional feed block hours.
So for the only point that matters to us...more hiring at mainline. That is the way I understand it. Block hours flat for UAL (regional +mainline) but shifting flying away from express.
