Pat - I think you've got nothing to worry about. It sounds like it's years away for SXM, they're not in the 1st group and honestly, can you see the airport really able to accommodate pre-clearance quickly? I have gone thru pre-clearance on Aruba and am not impressed. You have to get to the airport way early as you never know what the lines will be like - and we never travel on a Saturday. Can you just imagine the airport on a Sat. morning with pre-clearance? I've stood in line at the airline counter for almost an hour just to get my luggage tagged! I just don't see any advantage for those with Global Entry.
