## WiFi Availability and Connection

China Southern Airlines offers in-flight WiFi on select routes and aircraft, with plans for gradual expansion. The service activates when the aircraft reaches an altitude of over 10,000 feet (3,000 meters) and automatically deactivates below this threshold. To connect, passengers should enable airplane mode, turn on WiFi, select the "CSAIR" network, and then follow the instructions on the onboard portal or visit www.flycsair.com.

## Expected Performance and Usage

China Southern's in-flight WiFi generally supports web browsing, instant messaging, and email. While some product descriptions mention support for online audio/video streaming and video conferencing, real-world experiences and other official guidelines indicate that high-traffic activities like video streaming, large downloads, online gaming, and system updates are typically not supported or will experience significant speed limitations after a certain data threshold. For instance, connection speed may slow down after exceeding 30MB for general applications or 5MB for WeChat text and voice messages on domestic routes.

## Potential Interruptions and Restrictions

Passengers should be aware that the WiFi service may experience temporary disconnections of 5-10 minutes during satellite beam switches, particularly on international routes. Service availability can also be affected by unpredictable circumstances such as aircraft adjustments, maintenance, system upgrades, or device compatibility. Additionally, in accordance with Chinese laws, access to websites containing violence, pornography, or politically sensitive content is prohibited.
