Depending on your nationality and travel destination, in addition to a valid passport, you may need a visa or similar entry permit to be able to enter a country/region. Even if you are just transferring flights before flying to your final destination in another country/region, these requirements may still apply.
If you require a visa, you can visit an embassy or consulate for the country you wish to visit, or a recognized third-party visa center or service provider to find out more information on the process and make an application.
Please ensure your documents are valid before boarding the flight.
Hainan Airlines shall not be held responsible if a passenger is not allowed to board the plane due to issues with their documents.
