We've had GE for a few years now, and it definitely speeds up the immigration process. Unfortunately, unless you're traveling with only carry-on bags, the wait for your checked bags to either leave the airport or to take them through customs and re-check, is still as long as ever. We're always among the first people waiting at the carousels, and then the place gradually fills up with all the folks who don't have GE before the bags ever come off. It's still nice not to wait in that line, but the overall process isn't really any faster. And no, I'll never spend three weeks in SXM with only carry-on bags!
