What should I do if I want to change my previously booked ticket to Hainan Airlines?

Change visa.

You can change your visa through customer service. No matter where you bought the ticket, you can call the airline's telephone customer service to apply for a change unless it is specifically stated that you can't change it.

The information required to change a visa includes ticket number, ID number, flight itinerary, departure date and flight change date. Pay the change fee after providing it, and wait for the SMS after payment.
