Snacks
Choosing a travel snack can be tricky. I go for things that can’t be crushed, don’t smell, and generally don’t leave a mess. Domestically, some fruits can be fine, but if you’re flying international that can run you afoul of customs. Typically, I go for a granola bar or some beef jerky to tide me over between meals or on long flights. Also, please don’t be the person who brings a tuna sandwich on an aircraft full of people, the smell is pretty irritating to some folks.
