Yes, you can pack almost any solid food on a plane in 2026, including sandwiches, salads, fruit, and snacks like nuts or chocolate. The main restriction is the 3-1-1 rule for "liquid-adjacent" foods: anything that can be spread, spilled, or poured (like yogurt, hummus, peanut butter, or salsa) must be in a container of 3.4 oz (100ml) or less. In 2026, TSA officers may ask you to remove food from your bag to be screened separately because dense food items (like a thick brick of cheese or a large bag of trail mix) can obstruct X-ray images. For international flights, be cautious: while you can eat your food on the plane, many countries (like Australia or the USA) have strict agricultural laws that prohibit you from bringing fresh fruits, vegetables, or meat products off the plane and through customs. A supportive tip: always eat your fresh snacks before you land to avoid a potential $500+ fine at agricultural inspection.
