Be smart about snacks when flying

Packing food from home in your carry-on is still a good idea when you fly—it’s cheaper than buying fast food at the airport, and it will save you from hunger pangs if you experience long delays on the tarmac or if the airplane meal is just too disgusting. Just keep in mind that these days goodies must comply with the TSA (www.tsa.gov) guidelines, or they’ll be confiscated.
