Update: I packed snacks and an empty water bottle for a 4 day trip and spent $11 on food at the airport
I used to drop $40 easy on terminal food every trip (those $9 bagels add up fast). Last week I filled a zip bag with trail mix and jerky from Aldi, brought my empty bottle through TSA, and filled it at a fountain past security in Charlotte. What's your go-to cheap airport meal that doesn't get flagged at security?
