CHINA SOUTH AIR's stock soared 5.21% intraday on Tuesday, outperforming the broader market.

The surge follows a sharp decline in global oil prices triggered by optimistic negotiations between the United States and Iran, which directly alleviates the fuel cost burden for airlines. Fuel typically accounts for 25% to 40% of an airline's operating costs.

Analysts note sustained growth in air travel demand, with passenger expenditure showing year-on-year increases in April and May. With the summer travel season approaching after mid-June exams, supply and demand dynamics are expected to enhance airlines' ability to pass on cost changes, potentially exceeding market expectations.
