There are several great snack foods that you can bring onboard.
A long plane ride, airline food, exorbitant prices for food at the airport stores -- air travelers with empty stomachs would benefit well from bringing snack foods from home. However, Transportation Security Administration regulations limit what kind of munchies you can bring along on the flight, making it tricky to figure out what exactly to take in your carry-on luggage for those moments when you're hungry but can't bring yourself to have the in-flight meals.
Hard Snacks
Hard snack foods are the best choice. Though airlines typically provide travelers with a bag of peanuts or pretzels, it may not be enough to assuage your pangs of hunger. Bring your own nuts, pretzels, chips or jerky.
Dry Cereal
Dry cereal in a zip-top snack bag is a perfect in-flight snack for children. Mix in raisins or other dried fruit for a healthy vitamin boost.
Sandwiches
For those who need a heartier snack, sandwiches are acceptable food items, but go easy on the mayonnaise and vinaigrette. Liquid or sauce on your sandwiches may prompt additional screening. To get around this, carry your condiments and sauces in serving containers less than 3 oz. each in the 1-qt. zip-top bag allowed for carry-on liquids. Single-serving condiment containers can be found at your supermarket.
Vegetables
Carrot sticks, celery, broccoli and other crunchy veggies are healthy and convenient. Store them in a zip-top bag and stow away in your .
Sweets
Fliers with a sweet tooth can bring their favorite cookies, brownies and candy items. Sweets with a liquid or gel filling may be subjected to additional screening or disallowed at the checkpoint.
