You don’t want to be the person at the checkpoint – with open arms and bags being emptied, snacks caught, where his dignity is taken. Prevention is better than a cure. Know what you can carry through those terminals, so next time you have a happy journey.
Trail Mix

Official TSA What Can I Bring page affirms that trail mix is a solid food and will pass carry-on screening without restrictions. Nuts, Seeds, Dry Fruits in a Bag, it is literally the most accommodating passenger in the airport, and your most faithful travelling companion.
Granola Bars

The official Snacks page of the TSA is straightforward- solid food items can be placed in either carry-on or checked baggage, no queries asked. Granola bars are small, substantial, and come in every flavor under the sun. AFAR is of the opinion that they are never checked by TSA agents, no matter how much you carry.
Beef Jerky

AirHelp corroborates that beef jerky is a beefy food that is tough, dry, and needs no additional care whatsoever in your carry-on because it is not considered liquid. Protein-rich, inedible, and one that could not be refrigerated at all, jerky was practically designed to survive the mayhem of the days on the road.
Mixed Nuts

AirHelp assures that the nuts are solid food, which has been cleared to carry on, be it a small package of almonds or a large packet of mixed nuts. Full of nutrients, limitlessly transportable, and needing to get in on your part, like, open the bag, mixed nuts are the no-big-deal snack that will always board the plane.
Dried Fruit

The official What Can I Bring page of the TSA attests that dried fruit is cleared of security as a solid food, and that there are no carry-on prohibitions on this type of food. Blasts of energy- feather-light, naturally sweet, and with a serious pack of dried mango, apricots, and cranberries, the fruit products are packed into a very small space. Your carry-on will have a great day.
Crackers and Hard Cheese.

The official Snacks page of the TSA confirms that crackers are screened through as solid food, and the TSA food guide at CLEAR confirms that hard cheeses can be fully carried in the carry-on bag. Pair them. Enjoy yourself.
Protein Bars

The official Snacks page of the TSA assures that protein bars are solid food products that do not have any restrictions on being carried on as baggage. To prevent hours of hunger, high-calorie foods, shelf-stable, and created to endure precisely the type of unpredictable day on the road where people skip meals and move gates at the last moment.
Popcorn

The official What Can I Bring page of the TSA states that popcorn is a solid snack that goes through the carry-on screening with no problems whatsoever. Airy, light, with a nice selection of flavors, which is a closed bag of popcorn, is the type of snack you can grab without much effort, and consider an hour and a half of wait time virtually, virtually bearable.
Chips

AirHelp validates that chips are hard food, can be carried in carry-on bags, and do not in any way comply with the 3.4-oz. limit on liquids that TSA has. Crispy, comforting, and comes in all flavors like sea salt all the way to barbecue – a good bag of chips is actually the most amicable passenger at airport security. Savor each and every one.
Whole Fresh Fruit

The official What Can I Bring page of the TSA states that whole fresh fruit can be carried on board on all domestic flights within the US. An apple or a banana does not require any kind of packaging, refrigeration, or any kind of explanation at the checkout counter.
