Bandaranaike International Colombo Airport — Colombo, Sri Lanka

Sri Lanka channels nearly all of its international air traffic through CMB, situated in Katunayake roughly 30 kilometers north of the capital rather than within Colombo's city limits. The airport's name honors the Bandaranaike political family, whose members served as prime ministers of Sri Lanka across several decades and shaped much of the country's post-independence direction. SriLankan Airlines operates its primary hub here, connecting South Asia with the Middle East, Southeast Asia, and Europe, while the tropical island's status as a beach, wildlife, and cultural tourism destination keeps passenger numbers climbing steadily outside of periods disrupted by economic or political turmoil. A single main runway handles the bulk of operations, supplemented by a smaller secondary strip, and the terminal has undergone repeated renovation to keep pace with demand. Cargo traffic tied to Sri Lanka's tea, garment, and gem exports moves through the airport as well, underscoring its role as the economic gateway for the entire island nation.
