China Southern Airlines' stock surged 5.07% during intraday trading on Wednesday, driven by positive investor reaction to the company's latest operational performance.

The airline reported robust March operational data showing strong passenger traffic growth, with overall passenger revenue-ton-kilometers increasing 13.76% year-over-year. International routes delivered particularly impressive growth of 22.72%, while load factors improved across all segments, reaching 85.78% overall.

The data indicates a continued improvement in the supply-demand structure, with passenger traffic growth outpacing capacity expansion, which appears to have boosted investor confidence in the company's recovery trajectory.
