Singapore Airlines is Singapore's flagship carrier and one of the region's largest airlines in terms of revenue and carrying capacity. The company's hub is Changi Airport, providing regional and cross-continental passenger and cargo services destined to or transiting through Singapore. The company operates under dual brands: the full service carrier SIA and the low-cost regional carrier Scoot. It also owns stakes in SATs and SIA Engineering. In 2024, the merger of its associate airline Vistara with Air India resulted in Singapore Airlines owning a 25% stake in Air India.
