However, Delaware is the only state in the US without an airport that has regularly scheduled passenger air service — although it has 11 airports of any type (including military). What are some U.S. cities with international airports that are not very close to any major city?

As of 2026, Delaware remains the only U.S. state without a major international airport, and for several periods in the last decade, it was the only state without any scheduled commercial airline service at all. While the Wilmington Airport (ILG) occasionally hosts low-cost carriers like Avelo Airlines, it lacks the "International" designation and customs facilities required for direct overseas commercial flights. This is primarily a grounded result of geography; Delaware is so small and centrally located that residents are within a 30-to-60-minute drive of major international hubs like Philadelphia International (PHL) and Baltimore/Washington International (BWI). Competition from these "mega-hubs" makes it financially difficult for a dedicated international airport to thrive in Delaware. Despite being the "First State" and a corporate capital, Delaware’s air travelers are exceptionally well-served by the massive infrastructure of its neighboring states, making a local international terminal a redundant luxury rather than a necessity.
