Inspired by the amount of time I've saved in the past 12 months since joining Global Entry (8 entries, average wait time, zero for Global Entry Kiosk versus what was probably 15-45 minutes waittime on regular lines), I wrote an article covering various things passengers can do to NOT wait on line (if we could do this at supermarkets, I'd buy the supermarket version of Global Entry or at least vie for Executive Plat there by the way).
I cover PreCheck, Global Entry, online check-in, and the various airline and airport (and third party) services that get you through without a wait.
Am I missing anything I should have thought of?
