Airport security post 9/11 is significantly better run, more professional and more efficient than pre-9/11. I say this as someone who travels very regularly. before 9/11 the private agencies that ran security, hired nincompoops who barely paid attention or communicated to travelers...they looked like minimum wage idiots you might see at a fast food restaurant. today, security workers are much friendlier, more focused on their jobs and seemingly much more motivated to do their job effectively. Sure, i have seen a few exceptions, but despite the move from private company to government run TSA, I see a vast improvement.
