To get your international boarding pass at the airport in 2026, you usually have three options: a self-service kiosk, the airline's mobile app, or the check-in counter. Even if you check in online, many airlines require a "document check" for international travel to verify your passport and visa. You can often do this at a kiosk by scanning your passport; the machine will then print your boarding pass and bag tags. However, if the kiosk cannot verify your documents—or if you are traveling to a country with complex entry requirements—you will be directed to the full-service counter. In 2026, many major hubs like London Heathrow or Atlanta Hartsfield-Jackson have introduced biometric "Face-Boarding"; after a one-time document verification at the counter or kiosk, your face becomes your boarding pass at the gate. It is highly recommended to arrive at least 3 hours early for international flights to allow for these manual document verification steps, which cannot always be completed via a mobile app.
