Web check-in service has been laid out for the Hainan airlines expected on the day of departure. This means that, from 24 hours to 2 hours before the scheduled time, passengers can easily check out the registration on the website. Baggage still needs to be registered at the airport. For online check-in, the airline expects the completed electronic registration form which includes the passenger’s name and flight information as well as data on the passport. After completing the boarding card form, the passenger can create quick access to his email or device and take it to the airport door. The suitcases can be at the baggage check and the gate door registered through the airport terminal’s self-service check-in kiosks. Customers may use the express check-in service or auto-registration service. Despite the form of ticketing, the Express Check-in for passengers flying to Hainan Airlines hub airports is available. Direct and automatic check-in is available for travelers who may be used to the digital registration on the airline’s system if travelling with Hainan Airlines flight tickets ranging from and confirmed flights. It is prudent to set up two hours before the scheduled flight has passed for passengers to secure their cabin.
