well, i just flew from memphis to atlanta & back, with an extra nite in atlanta thanks to the idiot georgia fan who tried to breach security causing the entire atlanta airport to be evacuated & searched, so i have some current info. they hand-searched my carry-on luggage on both legs, & on the way out, i was randomly selected for a hand-frisk & removal of my shoes for scanning. i'd prob ship the packages just to cut down on the hassle, but if you don't want to do that, i definitely wouldn't wrap them. i'd allow a minimum of 2 hours before the flight; sometimes that'll be way too much, but every once in a while, it won't be enough.
according to the news, people aren't flying as much as before b/c they're scared, but i didn't see any of that or feel it myself. i will be flying alot less simply b/c it's not worth the time or trouble. anytime my drive would be about 8 hours or less, i'm going to drive, at least until the gov't figures out a faster way to confiscate everyone's finger nail clippers (gimme a break).
