No, when you use the Global Entry processing technology, you will need to use your passport or U.S. Lawful Permanent Resident card, if required. Global Entry cards do not work when entering the U.S. by air.

No, a Global Entry card cannot be used as a substitute for a passport for international air travel in 2026. While the card is an official U.S. government-issued photo ID and is "Real ID" compliant, its primary purpose is for land and sea border crossings between the United States, Canada, and Mexico (via NEXUS/SENTRI lanes). For any international flight, including those to "visa-free" countries, you are still legally required to present a valid book-style passport to board the aircraft and to clear immigration. The only exception where the card acts as a standalone travel document is at U.S. land border crossings (driving back from Vancouver or Tijuana). For 2026 travelers, it is a common mistake to think the "trusted traveler" status waives the need for the physical passport book; however, the card does not contain the necessary visa pages or ICAO-compliant machine-readable zones required by foreign governments for entry into their sovereign territory.
