To clarify -- summer flying is results in full flights. The United Strategy I referred to was in response to the OP's comment that UA should, "worry about the downstream affect of all of these new changes." My point is that the UA strategy now is to maximize the revenue from ancillary services like E+, which is why they changed the silver benefit so E+ was no longer available more than 24 hours in advance. They absolutely did worry about said downstream affect, and it seems to be working.
