When planning to fly with ANA (All Nippon Airways), one of the most important things to know is how early you can check in for your flight. ANA offers both online check-in and airport check-in, and the timeframes vary depending on your destination—domestic or international. For maximum convenience, ANA provides online check-in starting 24 hours before the scheduled departure time. This service is available through the official ANA website or the ANA mobile app. To check in online, you simply enter your booking reference or e-ticket number along with your name. Once checked in, you can select your seat, input your passport details for international travel, and receive your boarding pass electronically. This option is ideal for travelers wanting to skip long lines at the airport. Online check-in closes 75 minutes before departure for international flights and 20 minutes before domestic flights within Japan. If you're not checking luggage, you can head directly to the security checkpoint with your mobile or printed boarding pass. For those with checked baggage, ANA offers dedicated baggage drop counters at the airport. If you prefer or need to check in at the airport, ANA airport check-in counters for international flights usually open 3 hours before departure and close 60 minutes before the scheduled takeoff. For domestic flights, ANA advises passengers to arrive at the airport at least 60 minutes before departure, with counters closing 20 minutes before takeoff. To ensure a stress-free experience, especially during peak travel seasons, it is recommended to arrive at the airport earlier than the minimum time required, even if you’ve already checked in online. ANA also offers self-service check-in kiosks at major airports like Tokyo Haneda, Narita, Osaka Kansai, and Nagoya, allowing travelers to check in, print boarding passes, and tag luggage on their own. These kiosks generally operate during the same time frame as airport counters. Travelers flying Business Class, First Class, or holding elite status with ANA’s Mileage Club or Star Alliance Gold can access priority check-in counters, speeding up the check-in and baggage process significantly. However, passengers who require special assistance, are traveling with pets or infants, or are part of group bookings may need to complete their check-in process at the airport counters. It’s also important to confirm check-in details if you’re flying on a code-share flight operated by a partner airline, as their policies may differ slightly. In summary, ANA online check-in opens 24 hours before flight departure and is the fastest way to confirm your travel details. Airport check-in counters typically open three hours before international flights and close an hour before departure. Checking in early—online or in person—not only ensures a smoother airport experience but also increases your chances of getting a better seat and avoiding delays. Whether you're traveling domestically or internationally, early check-in with ANA allows for a more comfortable and efficient journey from start to finish.
