All Nippon Airways (ANA) offers flexible check-in options for both domestic and international travelers. For international flights, ANA allows online check-in starting 24 hours before the scheduled departure time, and this service remains available up to 75 minutes before takeoff. This is the ideal window for travelers who want to save time and choose their seats early. For those who prefer airport check-in, counters typically open three hours before the flight and close 60 minutes prior to departure. ANA recommends arriving at the airport at least three hours before international flights to allow time for security, immigration, and other procedures. For domestic ANA flights within Japan, passengers can check in online as early as 24 hours before departure, with airport check-in counters opening 90 to 120 minutes before the flight and closing 30 minutes before departure. This gives domestic travelers a convenient and efficient option to bypass long queues, especially during peak travel seasons. ANA's online check-in service is accessible through their website or mobile app, allowing travelers to select or change seats, add frequent flyer numbers, and download or email boarding passes directly to their devices. Passengers who complete online check-in and do not have checked baggage can proceed straight to the security gate, making the boarding process smoother and faster. For those with baggage to drop off, ANA provides dedicated bag-drop counters at all major airports. One key benefit of early check-in is the ability to secure preferred seating before options become limited. In addition to selecting seats, early check-in also enables travelers to confirm flight details, update passport information, and comply with destination entry requirements. For international routes, it’s essential to ensure all travel documents are accurate and completed in advance, especially when using the online check-in feature. Families, business travelers, and those with connecting flights benefit significantly from early check-in, as it helps reduce stress and provides better control over travel plans. ANA also supports self-service kiosks at many airports, which allow check-in as early as the counters open, adding more flexibility for travelers who arrive ahead of time. Self-service kiosks typically follow the same timeline as staffed counters and offer seat selection, baggage tagging, and boarding pass printing. ANA’s mobile app provides push notifications and reminders when the check-in window opens, giving travelers a helpful nudge to complete the process promptly. The boarding gate usually closes 20 to 30 minutes before takeoff, so passengers must arrive at the gate well in advance, regardless of their check-in method. For travelers flying in premium cabins like Business Class or First Class, ANA offers dedicated counters and early boarding privileges, further enhancing the early check-in experience. Overall, ANA recommends all passengers check in as early as possible, either online or at the airport, to ensure a smooth, stress-free travel experience. Knowing how early you can check into your ANA flight allows for better preparation, seat selection, and peace of mind, making the journey more comfortable from the start.
