You're likely to get the old product MCO-LHR or MCO-MAN, and it would be a pain in the ... to connect there from NYC (no airside transfer, disney crowds, 1000 mile detour). But if you're looking for a standard reward to europe from the south or southeast, it's a good gateway flight for availability. Last year I flew MSY-MCO-MAN-CDG in july at standard mileage rates.
