But B6 is terminal 5. Terminal 6 needs to to be rebuilt or massively renovated and isn't that big anyway. Why would we blow over a billion on terminal 4, remove instead of renovate terminal 3 just so we can have some insanely large alleyway, and then move into terminal 5, which is an average sized terminal pretty much good for narrowbody planes only? The aerial view of terminal 5 would make a pretty Delta sign though with its triangle shape and all. That might be worth a billion or two for an otherwise gate neutral experiment.

B6 may have brought something to the table before we invested over a billion and broke ground in terminal 4, but right now it seems like a really convoluted way to end up with the same number of gates in a narrowbody terminal and we'd obviously have to give something up, like 2 and/or 3, which I guess we could give to B6 in a swap but we'd have to renovate 3 first. That strategy reminds me of that scene in "The Jerk" when Steve Martin's family tore down their house and built an identical one.
