and just a couple of quick questions... Normally, we go the AC route and fly through Toronto, clear customs etc etc... What happens if we fly out of Halifax, into Boston or EWR, and then into MCO?? Flight lands and departs out of the same terminal - as far as I can tell...but do we have to leave security area, clear Customs, and then back to departure gate??? Last time through BOS was years ago, and have never flown through NYC before...any help is GREATLY appreciated!! TIA!!
