I am assuming these are to European Gateway Destinations? I make this assumption because from BOS I only get FRA MUC and ZHR. Personally I would love it to be all international gateways from the city. So for Boston, FRA, MUC, ZHR, PTY, and IST. If we are actually saying MP able Destinations DUB should be added. Maybe also PSL, GCM, MBJ, CUN. Some could say that YYZ/YUL/YOW/YHZ should be included, but I would say they are wrong.
