When you have a connecting flight when do you go through customs?

Do You Have To Go Through Customs During A Layover? Customs and immigration are usually required at the connecting airport for international flights. You don't always have to for domestic flights. In most cases, passengers on layover flights must clear customs and immigration at the first point of entry.



In 2026, you generally go through Customs and Immigration at your first point of entry into a country or a specific border zone (like the Schengen Area). For example, if you fly London -> New York -> Los Angeles, you must clear U.S. Customs in New York, collect your bags, and re-check them for the domestic leg. However, if you are transiting between two international flights (e.g., New York -> London -> Paris) and stay "Airside" in the international transit area, you typically do not clear customs in the transit country (UK). The main exception is "Pre-clearance" locations (like Dublin or many Canadian airports), where you clear U.S. Customs before you even board the plane, allowing you to arrive in the U.S. as a domestic passenger.
