Do you need passport for flight check in?

In the United States, you need a valid U.S. government-issued photo ID or a passport from your country of origin to travel through security. You must show that the name on your boarding pass matches the legal name on your unexpired government-issued ID.



Whether you need a passport for 2026 flight check-in depends entirely on your route and nationality. For International flights, a valid passport is non-negotiable and must often have at least 6 months of validity remaining. For Domestic flights within your own country (e.g., flying from New York to LA or Mumbai to Delhi), a passport is usually not required; you can use any government-issued photo ID like a driver’s license or a national ID card (like Aadhaar in India). However, as of May 2025, U.S. domestic travelers must ensure their license is REAL ID-compliant to bypass the passport requirement. A supportive 2026 note: many airports now utilize "Biometric Check-In," where your face is scanned against a digital passport or ID database, often meaning you only need to show your physical document once at a kiosk rather than at every single checkpoint.
