Air China's stock surged 5.12% during intraday trading on Monday, reflecting strong investor confidence in the airline's performance.

The sharp rise follows the company's release of its first-quarter results, which showed a significant profit turnaround. Air China reported revenue of RMB 44.536 billion, up 11.28% year-over-year, with net profit attributable to shareholders reaching RMB 1.714 billion. This represents a dramatic swing from a net loss in the same period last year and marks growth of 183.86%.

The company attributed the improved performance to capturing market opportunities, optimizing route structures, steadily expanding capacity, and strengthening cost controls. The broader airline sector also showed strength during the session, though elevated international oil prices remain a potential headwind for the industry.
