What then about the 764s from uCAL?

Someone explained to me btw why CAL can fly a 752, 753, 762 and 764 as one category and its because their aircraft are newer and the PFDs have tapes. But I don't think UAL's have the tapes. Not sure, maybe someone knows?

But if you have to seperate the categories and you're not a fan of the airplane anyways and you're about to have a fleet full of 777s... why not sell that odd ball aircraft to your competitor who also happens to be the only airline who operates the type other than you?

Or should we get as many 777s as we can given its capabilities? I mean we seem to fly 763s to where others fly 777s.
