Yes, you can bring almost any solid food items in your hand carry luggage in 2026. Snacks like sandwiches, fruit, nuts, chocolate, and dry crackers are perfectly acceptable at security checkpoints. The primary restriction remains the "Liquids, Aerosols, and Gels" (LAGs) rule; items like yogurt, peanut butter, hummus, or jam are considered "liquids" and must be in containers of 100ml or less and fit inside a single quart-sized clear bag. In 2026, some airports with advanced CT scanners (like London City or parts of JFK) allow you to keep larger liquids in your bag, but the 100ml rule is still the global standard for most hubs. Additionally, if you are traveling internationally, you must be careful about fresh produce or meat; while you can eat them on the plane, customs at your destination (especially in the US, Australia, or the EU) may prohibit you from bringing "unsealed" fruit or dairy products into the country.
