Before you leave home, do a quick mental scan. Is it solid? Pack it with confidence. Is it a spread or a sauce? Put it in a small container that’s under 3.4 ounces. When in doubt, freeze it — frozen solid items (like a yogurt tube or a gel pack) are treated as solids until they thaw.
And remember: the rules are the same for your checked luggage, but you have more freedom there. Checked bags can carry full-sized bottles of peanut butter, honey, and even that jar of pickles. Just wrap it in a plastic bag because things get jostled.
So go ahead. Pack that apple, wrap that sandwich, and smile at the TSA agent holding your homemade brownie. You’re not smuggling food; you’re bringing joy to 35,000 feet. Happy snacking, traveler.
