If you're flying with ANA (All Nippon Airways), knowing how early you can check in is essential for a smooth and stress-free travel experience. ANA offers both online and airport check-in options, and the timing depends on your departure and destination. For online check-in, passengers can check in as early as 24 hours before the scheduled departure time. This service is available through the official ANA website or mobile app. By entering your reservation number and passenger information, you can complete the check-in process, select or change your seat, confirm travel documents, and receive a mobile or printable boarding pass. Online check-in closes 75 minutes before international flights and 20 minutes before domestic flights in Japan. This early check-in allows you to skip the standard airport check-in lines and go straight to baggage drop or security if you have no checked luggage. If you do need to check bags, you should still arrive at the airport early enough to meet baggage deadlines. For domestic ANA flights within Japan, it is recommended to arrive at the airport at least 60 minutes before departure. For passengers who use online check-in and have no luggage, arriving 30 to 40 minutes in advance is usually sufficient, though earlier is always better during busy travel periods. For international ANA flights, passengers are advised to arrive three hours before departure, especially when traveling from major hubs such as Tokyo Narita, Haneda, Osaka Kansai, or Nagoya Chubu. The airport check-in counters for ANA international flights usually open 3 hours before departure and close 60 minutes before the flight, though some airports may have slightly different operating hours. Arriving early ensures you have enough time to drop off luggage, pass through immigration and security, and handle any travel document requirements. For Business Class, First Class, or ANA Mileage Club Premium members, priority check-in counters are available, which help expedite the process. At select airports, ANA also offers self-service kiosks for check-in and baggage tag printing, making the experience faster and more efficient. For special cases such as passengers requiring assistance, traveling with infants, unaccompanied minors, or those carrying oversized luggage, airport check-in is necessary, and arriving well in advance is strongly recommended. It’s also important to note that travelers on code-share flights operated by partner airlines may follow different check-in policies and should verify those details before departure. In conclusion, ANA online check-in opens 24 hours before departure and closes 75 minutes prior for international flights, while airport counters open about 3 hours before takeoff. For domestic flights, check-in closes 20 minutes before departure, and arriving at the airport at least one hour early is suggested. Taking advantage of ANA’s early check-in options not only saves time but also improves your chances of getting a preferred seat and a smoother boarding experience. To avoid last-minute issues, always complete online check-in as soon as it becomes available and arrive at the airport with ample time.
