Navigating Customs and Immigration on International Connecting Flights What Travelers Need to Know

Navigating customs and immigration for international connecting flights can be a complex process, with varying requirements depending on the departure and arrival countries.

Travelers need to be aware of specific procedures, such as the need to go through security and immigration checkpoints, collect and re-check their baggage, and comply with programs like the Visa Waiver Program and Electronic System for Travel Authorization.

It's crucial for travelers to allow ample time for connections and to carefully review the airline's guidance on the customs and immigration requirements for their itinerary.

The number of international connecting flights has increased significantly in recent years, with airports in Europe and the United States frequently experiencing high volumes of such traffic.

Global Entry, a trusted traveler program, can expedite the customs process for pre-approved travelers by allowing them to bypass dedicated lines and utilize self-service kiosks, saving valuable time during their international connections.

Travelers may need to go through customs and immigration processes in both their departure and arrival countries, even if they are on a single ticket itinerary with checked baggage, as some airports have separate terminals for international and domestic flights.

The Visa Waiver Program (VWP) allows citizens of participating countries to enter the United States without a visa for stays of 90 days or less, but travelers still need to meet certain requirements, such as having a return or onward ticket and proof of sufficient funds.

The Electronic System for Travel Authorization (ESTA) is a mandatory requirement for VWP travelers, and failure to obtain it can result in denied boarding or entry into the United States.

Automated Passport Control (APC) and Mobile Passport Control (MPC) programs have been implemented in some airports to facilitate the customs process, allowing travelers to complete their declarations electronically and potentially reducing wait times.
