A radical idea: think Canada

While you do need to clear customs, the electronic kiosks at most canadian airports, work very well. My wife flies on a foreign passport and we usually clear at exactly the same time. I think I travel frequently and in the last two years have never had more than as twenty minute wait in line, most times its about 5 minutes. On the otherhand on your return to your home thru Canada, you clear US customs in Canada and your clearance time would be negligible forUS transfers, you pretty just nod and walk thru.
