It's been several years since I've flown as pic possibly not since 9-11 and was curious as to the basic changes in rules/regulations. While I'm sure this question will generate several "Just read your Far/Aims" responses I'll do so but was just curious as to any BASIC rule changes that come to mind as a result to the Twin Towers horror.
Thanks in advance!

Don't bring anything sharp - including nail clippers, keychain knife, etc... and be prepared to take off your shoes and put them, your carry-on and everything from your pockets onto the belt to be scanned.

That's about it in a nutshell from my few flying experiences since 911.

Happy Holidays!
