In 2026, TSA PreCheck provides significant benefits when departing from a U.S. airport on an international flight, but it does not assist you once you land in a foreign country or when returning to the U.S. When leaving the U.S., PreCheck allows you to use the dedicated "trusted traveler" lanes, meaning you can keep your shoes, belt, and light jacket on, and leave your laptops and 3-1-1 liquids inside your carry-on bag. This saves an average of 15–20 minutes at major hubs like JFK or LAX. However, for the return journey to the U.S., PreCheck is useless for clearing Customs and Border Protection. To expedite that process, you would need Global Entry, which includes TSA PreCheck as a "bonus" benefit. In 2026, the new "Touchless ID" program is also expanding for PreCheck members on international routes with participating airlines like Delta and United, allowing you to use facial recognition to verify your identity at the bag drop and security gate without fumbling for a physical passport or boarding pass.
