Chinese airlines, including flag carrier Air China SSE:601111, will cut fuel surcharges on domestic flights from July 5, according to notices some airlines released this week.
The carriers will cut fuel surcharges for flights of 800 km (497 miles) or less to 50 yuan ($7.37) from 80 yuan.
Fuel surcharges for flights of more than 800 km will be cut to 100 yuan from 150 yuan, the notices showed.
Chinese airlines had lowered domestic fuel surcharges in June, the first since the start of the war in Iran.
Chinese airlines tend to revise fuel surcharges for domestic flights in tandem, state media has said, suggesting other carriers could follow suit in the coming days.
