In-person at airport using a self check-in kiosk To check in at a kiosk you will need one of the following: Confirmation number (usually sent via email if ticket is purchased online or through a travel agency) Credit card used for payment of the ticket. Passport.

Yes, you can check in at the airport using just your 6-character confirmation number (also known as a PNR or Record Locator), but you will still need to provide a valid government-issued photo ID to complete the process. In 2026, most airports feature self-service kiosks where you can type in your confirmation number or scan your passport to pull up your reservation and print your boarding pass and bag tags. If the kiosk isn't working, you can take your confirmation number to the full-service counter, where an agent will use it to locate your file. It is important to remember that for international flights, the confirmation number alone is not enough; the airline's system must also verify your passport data and any required visas before a boarding pass can be issued. If you are flying within the U.S., a REAL ID-compliant license or passport is mandatory at security. While having the confirmation number makes the process faster, many modern airline apps now allow you to check in automatically via facial recognition or by scanning your boarding pass from your digital wallet, making the physical "confirmation number" almost secondary to your biometric identity.
