Can I travel to Sansha City?

The serial number on the boarding pass is a number to prevent people with the same name from boarding the wrong plane, one name and one number. When you buy a ticket online, a text message will inform you that the ticket has been issued. If you buy air tickets directly on the websites of major airlines, you can register directly on the websites. It should be noted that when you check in directly online, you can't check your luggage, you can only carry it yourself. Therefore, passengers who need to check their luggage should check in at the airport. Different airlines generally have check-in areas and self-service check-in printers. On the self-service boarding pass printer, enter the personal ID number and follow the prompts to easily select the seat and print the boarding pass.
