How much before can we check-in online?

You can usually check in online starting 24 hours before departure. If checking luggage, you will need to bring your luggage to a staffed counter or checked luggage station once you arrive at the airport. Benefits of online check-in: Avoid potential check-in lines at airport.



In 2026, most major international airlines, including British Airways, Lufthansa, and Air France, allow online check-in starting 30 hours before your flight's departure. For U.S.-based carriers like Delta, United, and American Airlines, the standard window is typically 24 hours prior to departure. This window is critical for securing preferred seat assignments and obtaining digital boarding passes to bypass airport kiosks. Some airlines, such as Emirates and Qatar Airways, offer extended windows up to 48 hours for certain routes. It is important to note that if your itinerary involves a connecting flight on a partner airline, the check-in window is usually governed by the first departing flight's carrier, though specific visa or document verification requirements may still require a visit to the airport counter.
