Good luck this has to be the worst airport to renter the USA everything usually is ok until you go retrieve your checked bag then try to get through Customs which is in the middle of the luggage bays then you have to walk about 1/4 mile to give your bags to an agent then go upstairs to go through security again then to the plane ,which for us always seems to the farthest gate . Good luck also the walk to passport clearance seems to be a mile . I refuse to go through Miami
Plus the flight from BDL requires a overnight in Miami on American
