China Southern’s online check-in works well for most passengers, but there are some exceptions. If you are traveling with pets, need a wheelchair, are flying with an infant, or are part of a group booking, you will need to check in at the airport instead. Also, if your flight is a codeshare operated by another airline, online check-in may not be available through China Southern and must be completed with the other airline. At busy airports like Guangzhou Baiyun International Airport, using online check-in helps you avoid long lines and save time. Even if you check in online, it is important to arrive at the airport early. China Southern recommends arriving 2 to 3 hours before international flights and 1.5 to 2 hours before domestic flights to allow time for baggage drop, security checks, and boarding. Boarding gates usually close 15 to 30 minutes before the flight, and you must be at the gate on time, even if you already have your boarding pass. Passengers flying in Business Class or First Class can still check in online and enjoy priority boarding and lounge access at select airports. China Southern’s online check-in system is easy to use, supports multiple languages, and is available in many countries. In summary, yes, China Southern Airlines offers online check-in from 24 hours to 1 hour before departure for most flights. It is a fast, simple, and efficient way to prepare for your journey. Whether you are flying within China or to an international destination, online check-in helps make your travel with China Southern smoother and more convenient. Always double-check the airport rules and allow enough time for all pre-flight steps to avoid delays.
