There are two major changes:
- Travelers may now carry through security checkpoints travel-size toiletries (3 ounces or less) that fit comfortably in ONE, QUART-SIZE, clear plastic, zip-top bag.
- After clearing security, travelers can now bring beverages and other items purchased in the secure boarding area on-board aircraft.
Bruce Schneier hasn't posted about this yet, but it seems like there's actually some thought put into this and that it's a sensible security measure.
I'm truly convinced that the terrorists never actually planned to blow up planes with gels - they're just doing things to totally disrupt our air travel. Next they're going to wire explosives into the fabric on their pants, and we'll all have to fly without pants.
