If US were to expand to Asia/India wouldn't that increase usage of the A concourse. For example, if they flew PHL to DEL using about the same schedule as CO that would have a int'l arrival in the AM. After that aircraft came in it could depart for Asia around 10:30 AM. If they had service to HKG, NRT and PEK and flew them using similar schedules as ANA from the east coast you would have the departure occuring around 11 AM.
You could also have an AM departure to LGW with an overnight in LGW with a very early morning departure from LGW for a mid day arrival.
This would help to increase A utilization. Also if some of the Asian aircraft did overnights to LAX and SFO like the 67's used to do those aircraft could use the A concourses for AM arrivals.
You could also start doing runs to South America with overnight flights arriving in the AM.
