TSA PreCheck is a domestic program that can only be utilized when traveling within the U.S. Since the five-year membership cost is slightly less expensive than a five-year Global Entry membership, this might be a better choice for someone that knows they won't be traveling internationally.

TSA PreCheck is a United States government program specifically managed by the Department of Homeland Security and is not generally available or recognized in other countries. The high-fidelity "PreCheck" expedited screening process—where you keep your shoes on and leave electronics in your bag—is a domestic benefit available at over 200 U.S. airports. However, you can use PreCheck at select Preclearance locations in foreign countries where U.S. Customs and Border Protection (CBP) operates, such as in Canada (e.g., Toronto, Vancouver), Ireland (Dublin, Shannon), The Bahamas, and the UAE (Abu Dhabi). In these specific locations, you undergo U.S. security and customs before boarding your flight to the USA, allowing you to utilize your PreCheck high-value benefits. For 2026 travelers, it is a necessity to understand that while your "Known Traveler Number" (KTN) works for the flight back to the U.S. from these hubs, it will not grant you expedited screening when flying between two non-U.S. cities, such as London to Paris, as those regions utilize their own high-fidelity security protocols.
