How many months can a baby fly by plane? How to buy tickets?

Hello, my country's civil aviation department stipulates that children under the age of 2 are only charged 10[%] of the normal ticket price, and no seats are provided. Valid certificates of the child's or baby's date of birth, such as birth certificates, household registration books, etc., should be provided when purchasing tickets. You can enter your departure place, destination and departure time on the air ticket page of the Ctrip homepage, and check the 'carry infant/children', search out the air ticket and click on the reservation, and enter the baby's ID number in the passenger information, no need Enter contact information. Just pay after that.

14 days to 2 years old buy infant tickets (without seat), 10% of the adult economy class full price, free of machine building fuel fee, must be purchased together with the adult ticket, check the baby, and take the flight with the account book or birth certificate. <br/><br/>Ctrip homepage-tickets-choose origin and destination-choose date-check to bring baby-search-choose desired flight-place order<br/><br/>Help you, please Point to adopt!
