Well I would say it would depend on how busy the airport is.
If you have stuff you want to carry on, just bring it with you as normal.
They will xray it, and may randomly ask you to open it. Not very much different then it has been in the past.
I got taken aside and given the metal-detector wand treatment, they even made me take apart my belt buckle.
But otherwise most everything is operating as normal, I got to the airport @ 4:30pm for my 5:20 flight, and still had enough time to hit the bar for a few drinks and some fries before I boarded.
<< so what's your point? you want the gaurds watching ppl at the coke machine? >>
They have been for years, whats your point?
My point is, there is nothing stopping another incident like this from happening.
