Available from 24 hours until 75 minutes prior to the departure time for ANA international flights, or from 24 hours until 20 minutes prior to the departure time for Japan domestic flights. When flying with ANA (All Nippon Airways), passengers have multiple convenient options for check-in, both online and at the airport. Online check-in for ANA flights becomes available 24 hours prior to the scheduled departure time and closes 75 minutes before international flights and 20 minutes before domestic flights within Japan. This option allows travelers to confirm their seats, input necessary travel documentation such as passport information, and receive a mobile [1_866 551 1186 or printable boarding pass, saving time and streamlining the airport experience. However, travelers who are flying with pets, unaccompanied minors, or those requiring special assistance must complete check-in at the airport counter. For those opting for airport check-in, ANA recommends arriving early to allow adequate time for all travel procedures. Check-in counters typically open three hours before international flights and two hours before domestic flights, with counter service closing 60 minutes before international departures and 30 minutes before domestic ones. Passengers should ensure all steps, including baggage drop and security screening, are completed in advance. Boarding gates usually close 10 minutes before departure, so promptness is crucial. Using ANA’s online check-in option is ideal for travelers looking to skip the lines and proceed directly to baggage drop or security if they have no checked luggage. However, even with online check-in, it’s still important to arrive at the airport early to accommodate any unexpected delays, especially during peak travel times. By utilizing ANA’s early and flexible check-in options, passengers can enjoy a smoother, less stressful start to their journey.
