DL is going to A East, the "original" A (A-West, gates A14-26, is the new international terminal, by far the nicest in the airport). I would expect DL
to wind up at the end of the terminal, which is a rounded end comprising roughly gates A6-13, but I'm not certain. These are currently common use gates, and US uses them frequently as overflow for international service from A-West. US was opposed to the DL
move as this might require them to use mobile lounges for some international flights next summer. AA
, USA3000 and some charters also operate out of A-East. BA
recently moved over to A-West, where AF
They are vacating E in part due to the pending construction in the terminal to give it a hammerhead-shaped extension similar to D. This will temporarily reduce the number of gates in the terminal hence the move. AFAIK NW
will stay put in E. The construction currently going on between D and E is to create an expanded and unified security checkpoint, which should substantially improve the security lines at both terminals and connect E to the rest of the airport behind security, which not only allows folks in E to wander over to the other stores and B-C food court but will also allow connections and gate changes for WN
, which uses D1-4 as well as much of E. Currently you have to reclear security to go between terminals, and E is the only "security island" in the airport.
