Strange. It seems to me that these flights always provide heavy loads as the 8am ORD-SFO connects passengers to Pacific flights while the 1pm SFO-ORD feeds passengers coming from overseas.

I understand if they just don't have the needed 777 aircrafts due to the military desire to use them but these are always full flights and used to be 744's. I sure hope they don't downgrade these flights. I just flew a IAD-ORD flight on a 744 the other day when they upgraded it from a 777, so I know UA has these things waiting for use.
