Yeah, lots of things get discussed by management without ultimately being acted on, but I think I heard rumblings about that myself. United did in fact, decades ago, have multiple dispatch offices - I believe one in SFO, one in ORD, and one in IAD? I could be wrong on the exact locations, as it was well before my time, before moving everyone to Chicago, I think in the 1980s? Northwest also had a dispatch office in Japan for many decades. All this being said, the current management at UAL seems very "unitary" in the sense of enjoying having everyone in the same room. I'm not saying a split office is impossible, but I'd be really surprised if it happens any time soon.
