Airlines in China are expected to carry close to 29 million passengers during the Spring Festival holiday period, which falls on Feb. 14-Feb. 21 this year, according to the Civil Aviation Administration of China (CAAC) on Jan. 8.

The air passenger flow totaling 28.94 million will be 12.5 percent more than last year's same period, the busiest time for transport companies as many Chinese rush back home for family reunions.

The administration urged airline companies to make proper arrangements of flights, in a bid to ensure a smooth passengers flow and transportation of important goods for the holiday.

It also asked the airline operators to pay close attention to the weather condition and airline operation and improve contingency plans in case of flight delays.
