After you complete the online check-in process—usually available 24 hours before departure—you receive your digital boarding pass, which is the most critical step. You can save this to your smartphone’s wallet (like Apple Wallet or Google Pay) or print it out. In 2026, once you have checked in, the airline’s system officially marks you as "ready to fly," which helps protect your seat if the flight is overbooked. When you arrive at the airport, if you have only carry-on luggage, you can skip the check-in counters entirely and head straight to security. If you have checked bags, you must proceed to a "Bag Drop" kiosk; many modern airports now use self-service kiosks where you scan your mobile boarding pass, print your own bag tags, and place the luggage on a motorized belt. If you are traveling internationally, checking in online also triggers the airline’s final document verification; if the system cannot verify your visa or ETIAS status digitally, you may still be required to visit a "Document Check" desk at the airport before you can proceed to the gate.
