So no classes in those months at all?

That doesn't seem to help very much. It seems there's always at least some need, in some fleets, to have some amount of NH throughput. Seems like an extreme overreaction to have zero NH's for 2 months, even considering pulling some SLI capacity to fly the line.

Not to mention that July and especially August NH's wouldn't even be filling the sims until Sept or later anyway in many cases.
