Security. Sucks yes...but at this point I'm back to arriving 1 hr before flight time and making my flights without much of an issue. Thats roughly the same as pre-9/11.
B.S. You need really broad definitions of "roughly" to make that comment work. I've personally gotten my dad and his bags on an airplane after having arrived at the airport 10 minutes prior to departure. *That* was pre-9/11. Also, pre-9/11, I could pull 22T up to the gate with a passenger and bags and put them directly on a commercial carrier. *That* was also pre-9/11. Commercial air travel will never again be "roughly pre-9/11"-esque.
