I am trying to find a flight coming back from Boston or NYC that is of the international variety so that a mileage upgrade reaps the most value. Does anyone know what the most efficient way of finding this info out is? I have tried the Star Alliance electronic timetable and can find some 767-300 flights out of JFK but can't tell if they are domestic or international versions. I would rather fly out of Boston- so if anybody knows about flights out of there (November 7 would be the flight date at any time of day.). Any help is deeply appreciated!
Thanks!
