For Chongqing Airlines customer service numbers, see the "Contact us" page on the official website (www.chongqingairlines.cn).
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.
