The downside of Bangor westbound is the US requirement that any flight entering the US has to clear customs/immigration at the first stop, which means you have to get everyone and their bags off, everyone through all the procedures, through security again, and back on. I believe passengers would also lose any duty free drinks from Heathrow at the security recheck. For a scheduled operation it probably adds one to two hours to the trip, and quite possibly knocks the crew out of hours on longer runs.
It can suit some charter operators going to smaller points in Florida, but for mainstream schedules US tech stops are to be avoided. Must improve Gander's business considerably.
