Good suggestion about the food. It would come in useful if the flight arrives really late at a remote airport and you can't find food. I might add something like a pop tart/granola or trail mix, definitely candies which don't melt (if traveling to the warm tropics) or goes bad quickly.Garrobo:I've gotten my carry-on down to my regs/prescription mask/computer/camera, some candy and a couple of sandwiches. I figure that I can sustain myself with the food items...
