In 2026, checking in for a flight without a passport is entirely possible for domestic travel, provided you have another "Gold Standard" form of government-issued identification. In the United States, as of May 2025, you must present a REAL ID-compliant driver's license (marked with a star) or an acceptable alternative like a Global Entry card or U.S. military ID. A grounded new development for February 2026 is the TSA ConfirmID program, which allows travelers without a physical ID to pay a $45 fee to attempt identity verification via an online form. In countries like India, digital platforms like DigiLocker and mAadhaar are high-fidelity, supportive ways to verify your identity at the gate without carrying physical documents. However, for international travel, a passport remains a "hard-fail" requirement. To ensure a supportive and frictionless journey, always check your airline's app 24 hours before departure to see if you can complete a "digital check-in," which often allows you to bypass the counter entirely if your "Bujan" identity is already on file.
