Passengers flying between Shanghai Hongqiao International Airport and Beijing Capital International Airport can now change their tickets between different airlines, following the launch of a new trial service on May 6, according to Shanghai Airport (Group) Co Ltd.

As part of efforts to improve express flights between Beijing and Shanghai, Shanghai Hongqiao International Airport has launched the flight change service in collaboration with China Eastern Airlines and Air China. The trial will run until August, with plans to refine the service based on passenger feedback, according to Shanghai Airport (Group).

Passengers holding one-way tickets between Shanghai Hongqiao and Beijing Capital airports with a discount of 40 percent or less can switch to flights operated by either China Eastern or Air China on the same day, after paying the fare difference.

Nearly 80 flights operate daily between Shanghai Hongqiao and Beijing Capital airports, making it the busiest air route in China. As about 90 percent of these flights are run by China Eastern or Air China, the new service is expected to better meet the needs of business travelers and frequent fliers, offering a more secure, convenient, and efficient travel experience.
