Fooman's reply to the 'Super typhoon' to hit Philippines thread got me thinking about what happens if the SHTF while you're on travel. All your food, water, and tools are back at home. Your kit's been stripped down to get it through TSA, and you're in an unfamiliar city which may or maynot have working utilities.

1) What do you need to know before leaving for the airport?

2) What should you pack (carry on only and checked luggage travel) to ensure TSA doesn't confiscate it?

3) What do you buy when you get there (before the disaster)?
