China Southern Airlines customer service numbers are listed below. For changes, refunds or baggage issues, calling the hotline or using the official web chat is usually fastest.
If you booked via a third-party platform, contact the platform first for changes and refunds; check-in, baggage and schedule-change questions can go straight to the airline.
Call smart: peaks hit during mass delays and weekday mornings — off-peak calls connect faster. Have your 13-digit ticket number or booking reference and passenger ID ready; the official app's chat can usually handle changes and baggage purchases too.
