Hainan Airlines allows passengers to check in online or at the airport, with specific timeframes for each method. For international flights, online check-in opens 48 hours before departure and closes 2 hours before departure. For domestic flights and flights to or from the USA and Canada, online check-in is available starting 24 hours before departure and closes 2 hours before the flight. Through online check-in, passengers can select seats, confirm flight details, and obtain a boarding pass to print or use on their mobile device. However, passengers requiring special assistance, traveling with infants, unaccompanied minors, or needing wheelchair services must check in at the airport counters.

Airport counter check-in for international flights typically opens 3 to 4 hours before departure and closes 60 minutes prior to takeoff. For domestic flights, counters generally open 2 to 3 hours before departure and close 40 minutes before the flight. It is recommended that passengers arrive at the airport at least 3 hours before international flights and 2 hours before domestic flights to allow sufficient time for check-in, security screening, and boarding. Self-service kiosks are available at select airports, allowing travelers to check in, select seats, and print boarding passes starting about 3 hours before departure. These kiosks usually close 30 to 45 minutes before the flight but may not be available for passengers needing special assistance or traveling with infants.

To avoid issues, passengers should check in as early as possible within the permitted timeframe. Those with checked luggage are advised to complete the check-in and baggage drop-off well before the counters close. It is also important to have all necessary travel documents ready, including passports, visas, and any required health forms, to prevent delays during check-in. Overall, Hainan Airlines offers flexible options for check-in to accommodate different passenger needs, with clear timeframes that allow for efficient preparation before departure. Passengers who plan ahead and follow these guidelines can expect a smoother travel experience when flying with Hainan Airlines.
