If you’re flying with All Nippon Airways (ANA), one of the most frequently asked questions by travelers is: How early can I check into my ANA flight? Whether you’re traveling domestically within Japan or internationally, ANA offers several convenient check-in options to ensure your journey starts smoothly. For most passengers, online check-in opens 24 hours before the scheduled departure time. This applies to both domestic and international ANA flights. With online or mobile check-in, you can select your seat, confirm your reservation, and even receive your boarding pass digitally. For international flights, online check-in closes 75 minutes before departure, while for domestic routes, it closes 20 minutes before departure. This option is especially useful for travelers with carry-on luggage only, allowing them to bypass the check-in counter and head straight to the security gate. However, if you are checking in baggage, traveling with pets, requesting special assistance, or are an unaccompanied minor, you’ll need to check in at the airport counter. For those who prefer traditional methods, airport counter check-in for international flights usually opens 3 hours before departure and closes 60 minutes before the flight takes off. For domestic ANA flights, counters typically open 2 hours before departure and close 30 minutes prior. Additionally, ANA offers self-service kiosks at many major airports, which allow you to check in, print your boarding pass, and tag your luggage quickly and easily. These kiosks usually become available two to three hours before flight time. Regardless of your check-in method, it’s important to note that ANA boarding gates typically close 10 minutes before departure, and boarding generally begins 30 to 40 minutes prior for international flights. To ensure you have enough time for security screening, immigration (if applicable), and unexpected delays, it’s strongly recommended that passengers arrive at the airport at least 2 hours before domestic flights and 3 hours before international flights. Checking in early not only secures your seat preferences but also minimizes the risk of missing your flight due to long lines or airport congestion. Moreover, passengers who check in early are more likely to receive upgrades or preferred seating if available. For those traveling in ANA’s premium classes or with ANA Mileage Club status, dedicated check-in counters and early boarding privileges provide added convenience and comfort. In summary, you can check in for an ANA flight as early as 24 hours before departure online, and 3 hours prior at the airport for international flights. Being aware of these timelines can help you avoid stress, ensure a smoother airport experience, and make your ANA journey as enjoyable as possible. Whether you're flying economy or business class, domestic or international, ANA’s flexible and passenger-friendly check-in process is designed to make your travel seamless from the moment you start your journey.
