Mid-Atlantic - PHL - UA's Terminal D now also DL,AA and SWA?

Last week at PHL I was speaking to a UA GA asking why DL planes were now in the gates around UA in terminal D? She said DL has moved from A and that AA was also moving from A to D around UA. SWA should move more flights to E.

Has anyone else heard anything about DL and AA sharing D with UA?

Now the security line will be even longer with all of the DL and AA pax. this is probably because SWA is expanding in PHL.

US has A,B,C,F i believe in PHL and other airlines are in D,E.

I don't know any official news (others may), but Airtran left the D terminal and WN will move all to E once the renovations are finished. The old NWA gates in E have been abandoned by Delta and they've moved to D. Don't know about AA. Quite frankly, I'd rather have Delta in D than WN, fewer Ma and Pa Kettles. There is a statement on the PHL airport's website about Delta moving to the D terminal at this link: http://www.phl.org/terminal_map_d.html
