One of United Airlines’ problems as of late has been dispatch reliability. Dispatch reliability is a measure of an airline’s ability to dispatch the flights, get them off the gate and on their way. Single type airlines like Southwest have a very high dispatch reliability score, due in no small part to only flying one type of plane. With United’s merger with Continental, the number of types of planes in service nearly doubled. This makes it difficult to keep up a high level of dispatch reliability. For example, if an airport has 737, A320, and ERJ-145 service, United has to keep common spares on hand for each type of plane at that airport. That is both difficult and expensive, but all too common. United has chosen to combat this problem by establishing certain discrete bases for their aircraft. Houston will be home to a large number of A320/319’s, Denver will be home to the 737, and now San Francisco will be home to the only 747 base. Basically if it is a long-haul route on UA out of SFO it will probably be on a 747. This doesn’t mean other airports won’t see the 747, it just means the plane originated from them.

Some of the route changes occurring are as follows

KIX, NRT, FRA, LHR, and NRT-HNL will all move to 747 service.

Of course nothing is official until you see it in print, so right now this is just a rumor.
