Erik ---- Massport has plans to expand Terminal E in the direction of the aircraft parking area and hanger
I'll believe it when I see it. A Terminal E expansion has been in the works since "Logan 2000".
However, I see Massport's chance with American Airlines's bankruptcy. Given the fact that Boston is now really nothing more than a spoke for AA, I think it's highly likely that they'll close down their maintenance base, or at least move it to a smaller facility. They simply have no reason for that large hangar anymore, given that with the exception of London all their flights are to their hubs. When that happens, I see Massport taking that area for expansion of Terminal E. However, given that international service has largely not expanded in recent years, some of the pressure is off now that Northwest is out of E which freed up a bit of space. In the mid-2000s, it was a daily juggle how to fit the flights in, especially since Massport inanely follows a first-come, first-served system for gate allocation.
And yes, A was originally planned to be an international facility. However, three things have happened since then:
1) The FIS facilities were scrapped from the design. Delta had plans for a small international network from Boston but this was scrapped during their bankruptcy. This was the final nail in the coffin for FIS facilities. This would require a pricey reconfiguration of the terminal to accommodate it. No international facilities are even roughed-in for eventual conversion.
2) Delta and Massport reconfigured the gates for a domestic operation. So this would require either a change in the configuration of gates or the ability to run the operation with several gates out of commission while widebodies sit on stand.
3) Delta no longer controls the terminal. Delta, during its bankruptcy in the mid-2000s, defaulted on its bond payments to Massport and Massport gained control of the terminal from Delta. While it looks likely that the combined United/Continental will be in Terminal B, it's in no way certain that Delta will gain back the gates that Continental currently occupies. If Delta doesn't get that space back, even if they were to get an FIS facility, Delta cannot run its domestic schedule with several of the gates blocked out by Air France, Alitalia and Delta's Amsterdam and London flights. For instance, a Delta A330 and the Air France 747 would at least remove an additional adjacent gate out of use and would probably restrict the size of the aircraft on the other adjacent gate. Certainly, they have a say in the terminal, but Massport will act in their own best interests and not that of Delta/
