On August 20, China Southern Airlines launched the “Last-Moment Boarding” service (referred to as “One-Moment Boarding”) on its Shanghai Hongqiao to Guangzhou round-trip route. This is the second route to pilot the service after the Guangzhou to Beijing Daxing route. The service removes the previous requirement for check-in counters to close 30 minutes before departure. Passengers without checked luggage only need to pass security and arrive at the boarding gate before it closes (15 minutes before the scheduled departure time) to board.
Currently, all 10 daily round-trip flights between Shanghai Hongqiao and Guangzhou are piloting the “One-Moment Boarding” service. China Southern Airlines’ Shanghai branch will optimize key procedures such as check-in and baggage handling to improve operational efficiency, shorten passenger waiting times, and deliver a more efficient and smooth travel experience with a “warm and meticulous” service philosophy.
The Shanghai Hongqiao to Guangzhou route has a high proportion of business travelers, making it an ideal choice for launching the “One-Moment Boarding” service to benefit more passengers. In the future, the airline plans to expand this convenient service to more routes.

The “One-Moment Boarding” service is designed with passenger needs in mind. Through smart technology upgrades and operational changes, it breaks from the industry norm of closing check-in counters 30 to 40 minutes early. It reduces restrictions on ticket changes due to traditional check-in deadlines and offers convenience for last-minute rescheduling, unexpected business trips, early or late flights, and frequent business travelers.

It is important to note that the “One-Moment Boarding” service currently does not apply to passengers with checked luggage. For those with baggage to check, the cutoff time remains 30 minutes before departure on the Shanghai Hongqiao to Guangzhou round-trip route.
