How many hours before flight can you check in online?

Check-in times You can check in online or from the app starting 24 hours before and up to 45 minutes before your flight (90 for international). To check bags or check in at the airport, you must be there a certain amount of time before scheduled departure: Within the U.S. – 45 minutes.



For most major international and domestic airlines in 2026, online check-in typically opens 24 to 48 hours before the aircraft's scheduled departure. For example, carriers like Emirates and Saudia allow check-in starting 48 hours in advance, while many US-based airlines like Delta and United open their window exactly 24 hours prior. This high-fidelity digital window allows you to confirm your attendance, select or upgrade your seat, and receive a mobile boarding pass. Checking in as soon as the window opens is a high-fidelity strategy to secure better seating and avoid being "bumped" in the event of an overbooked flight. The online check-in process usually closes 60 to 90 minutes before departure for international flights and 45 minutes for domestic ones. It is a high-fidelity requirement to complete this process early, as it streamlines your airport experience and allows you to proceed directly to security or the "Bag Drop" counter, significantly reducing your total transit time through the terminal.
