How online check-in works
China Southern Airlines offers convenient online check-in through www.csair.com and its mobile app. Check-in opens 24–30 hours before departure for most routes; for domestic flights, online check-in typically becomes available from 2 p.m. the day before departure. Check-in closes 1 hour before departure. There are no fees for online check-in.
Online check-in steps:
- Visit www.csair.com or open the China Southern Airlines mobile app.
- Enter your booking reference and last name to access your reservation.
- Review flight details and select your seat (if not already assigned).
- Confirm baggage allowance and any special requests (meals, mobility assistance).
- Complete the check-in process and download or save your boarding pass.
Practical tip: Complete online check-in as early as possible to secure preferred seat selections, especially on popular routes. If you require checked baggage or have special services, allow extra time and consider arriving at the airport earlier than standard guidelines.
