Yes, you can absolutely pack snacks in your hold (checked) luggage, and in many ways, it is easier than carrying them in your hand luggage. Solid snacks like chocolate, biscuits, nuts, and dried fruits are allowed without restriction. The main advantage of hold luggage in 2026 is that it bypasses the "3-1-1" liquid rule; you can pack larger jars of peanut butter, honey, or jams that would be confiscated at a security checkpoint. However, you must be aware of the customs regulations of your destination country. Most nations strictly prohibit the entry of fresh fruits, vegetables, meat, and unpasteurized dairy to prevent the spread of agricultural pests and diseases (like Foot and Mouth or fruit flies). If you are caught with a ham sandwich or a fresh apple in your suitcase in countries like the USA, Australia, or the UK, you could face heavy fines. To stay safe, only pack "processed" or "shelf-stable" items in their original commercial packaging, and always declare any food on your customs form to avoid legal trouble.
