Chhatrapati Shivaji Maharaj International Airport — Mumbai, India

Chhatrapati Shivaji Maharaj International Airport carries the code BOM, a legacy of the city's former name, Bombay, which persists in the code even though the city has been called Mumbai since 1995. Named for the Maratha king Chhatrapati Shivaji, the airport sits at 39 feet above sea level, operating two intersecting runways rather than a parallel pair. BOM ranks among India's busiest airports and serves as a major hub for Air India and other domestic carriers, handling a dense mix of international long-haul routes and domestic connections across the country. Mumbai's status as India's financial capital drives heavy year-round business travel through the airport, while the crossing layout of its runways creates scheduling constraints that can lead to delays during peak hours, particularly around the monsoon season. The airport has undergone extensive modernization, including a new integrated terminal that consolidated domestic and international operations under one roof, along with expanded cargo facilities serving Mumbai's trading economy.
