You can bring croissants, baguettes, sandwiches, chaussons aux pommes, or any other carby delicacy that you crave both on the plane and in your checkin luggage. While these might not last long, they are a great snack that beats airplane food and might even last long enough for breakfast at home.

You can absolutely bring croissants back from Paris to the United States or the UK, provided they are for personal consumption and are carried in your hand or checked luggage. According to 2026 TSA and Customs guidelines, bread, pastries, and baked goods are generally permitted because they are processed and do not pose the same agricultural risks as raw fruits, vegetables, or meats. However, it is a critical peer-to-peer warning to ensure your croissants do not contain fresh meat or soft "unpasteurized" cheeses, as those specific fillings could be confiscated by customs agents. For the best "at-home" experience, many travelers buy their croissants on the morning of their flight, wrap them individually in parchment paper, and place them in a hard-sided container to prevent them from being crushed in the overhead bin. When you arrive home, a quick 2–3 minute "refresher" in a 180°C oven will bring back that famous Parisian crispness. Just remember to declare all food items on your customs form; even though they are allowed, failing to declare them can lead to unnecessary questioning or fines if a beagle at the airport sniffs out your buttery stash.
