Other side of the coin ... so if we do nothing other than say "no" ... what's to keep Delta from moving the operation to HND as they can can codesharing out of HND?

Answer nothing.

I think my record as a scope hawk is pretty well established here. That being noted, it is my opinion our MEC made the right decision with the decision they faced.

With overflight + the Olympics in 2020, my guess is that we will be fine on block hours. The 15% will act as a check valve that helps us to ratchet up our flying and failing that, we have some scope redundancy ... a floor.
