Personally, I really don't think this is a good idea.
First off, given the arrival time into BOS for AA95 (15:20). That's also the time that Air France and Delta's FCO service will arrive. INS in BOS is gravely understaffed, to the point that they can only process one flight every 20-25 minutes. I work for BA, and one day our flight arrived at 12:55, but were not able to begin offloading our pax until 13:40 because of a back-up in immigration. Can you imagine the waits if all three (AF 343/777, DL 763, and AA 777) show up at the same time?
Last Summer we at BA had 2 744s and 1 777. The preliminary timetables are showing 2 777s and 1 744, however our flights go out chokka, and it's quite possible that will be reverted back to last Summer's schedule. But, as of now the flights look like this
BA: 2 772s + 1 744
VS: 1 744 (LHR) + 1 742 (LGW)
AA: 3 772s
To me...that's a bit excessive. That's eight daily flights on nothing smaller than a 777. Even though our 772s only hold at max 224 passengers, that's still a lot of capacity.
