Portland International Jetport — Portland, United States

Portland International Jetport, using the code PWM, occupies a peninsula site close to Casco Bay and gives Maine's largest city a compact, easily navigable airport well suited to a state that prizes small-scale, unhurried travel. Scheduled airlines connect Portland to major East Coast hubs and a handful of seasonal leisure markets, supporting both the city's growing food and tourism economy and the broader southern Maine coastline stretching toward Kennebunkport. Unlike the sprawling terminals of larger New England airports, PWM keeps arrivals and departures within a short walk of parking and rental facilities, a feature locals frequently cite as a practical advantage. The airport has expanded gradually over recent decades to accommodate rising passenger numbers without abandoning its small-city character entirely. For visitors drawn to Portland's restaurants, working waterfront, and nearby lighthouses, the Jetport typically serves as their very first and last impression of Maine.
