PIT is being downsized (not closed) because it is and has essentially been for several years - a money looser - Period.PIT is being closed because it is too close to PHL.Period. ......If US had succeeded in acquiring DL, PHL and CLT both would have been likely casualties to JFK and ATL. At best, PHX, SLC, JFK, BOS, DCA, ATL, (and CVG, maybe) would've been spared...call it as I see it...
Evidently you were not too involved with the DL takeover plans. The stated plans in the merger documents/presentation clearly stated the 2 largest/main hubs would be ATL and PHL - not JFK.
