For those of you who travel out of MIA, American Airlines security checkpoint #2 recently started to allow TSA Pre participants to go through expedited security (no line, no shoes or belts off, no taking computer out of bag, etc.) when travelling to an international destinations. Previously it was only available for domestic flights. Not sure when they started allowing international travellers through too, but it's a welcome change!
Went through security yesterday in 60 seconds. The regular TSA line had 100+ people in it, all staring at me with a "WTF?" look on their faces.
