Does online check-in require passport?

In some cases, you'll need a passport, while in others an ID such as a driver's license might be enough. During online check-in, airlines ask for the number on your identification document and its expiration date.



For almost all international flights in 2026, online check-in does require your passport information. Airlines are legally mandated to collect "Advance Passenger Information" (API) for security and immigration purposes before the flight departs. During the check-in process on the airline's website or app, you will be prompted to enter your passport number, expiration date, and country of issue. Many modern airline apps now allow you to scan your passport using your phone’s camera to ensure accuracy. Even if you successfully check in online and receive a digital boarding pass, you will likely still need to visit a document verification counter at the airport so a staff member can physically verify your passport and any required visas before you are allowed to proceed to the gate.
