Douglas-Charles Airport — Marigot, Dominica

DOM refers to Douglas-Charles Airport, the main international gateway to the Caribbean island of Dominica, located near Marigot on the island's northeastern coast. Named after two former Dominican prime ministers, the airport handles regional flights connecting Dominica to neighboring islands like Antigua, Guadeloupe, and Puerto Rico, since its runway length has historically limited larger long-haul aircraft. Dominica markets itself as the Nature Island of the Caribbean, prized for rainforests, volcanic terrain, and diving rather than beach resorts, and DOM serves as the primary entry point for ecotourists. The airport has undergone periodic expansion discussions to accommodate growing tourism demand and improve resilience following hurricane damage that has affected the island's infrastructure.
