So the flying thread has been hijacked... why am I not surprised?
Some security advice from a former business traveler:
If you're checking bags, carry on only what you'll need on the flight and what you can't do without. This means your wallet, cell phone (you can't use it in flight but you don't want to lose it), reading material, prescription meds, prescription glasses, toiletries (nothing metal like nail scissors), etc. Pack neatly and don't lock your checked bags - at many airports, TSA does hand inspections of checked luggage, and if you lock your bag they'll break the lock. Your checked bags should have ID inside and out to increase the chance they'll get back to you if they're lost.
Wear as little metal as possible. A bra without an underwire is a good idea. Make sure your shoes either (a) don't contain metal, or (b) can be easily slipped off for the x-ray. (I found out the hard way that my favorite pumps contain metal

)
If you have a cell phone or laptop, keep it easily available as it has to go through the x-ray by itself (not in a bag).
I have a blazer that I always wear when I fly - the "Frequent Flyer" jacket from Norm Thompson (I don't know if they still make it). It has a lot of pockets, many of which have zippers. I throw my keys, wallet, jewelry, etc. into the jacket, then run the jacket through the x-ray, and make sure no one else walks off with it!
As for navigating the airport, most airports are well signed, and you can always ask airport staff for directions. When you check in, ask for directions to your gate, and you'll be all set.
Oh, watch the monitors for gate changes and delays. The last time I flew, the gate was changed 5 times
You'll be fine! Have a safe trip.
