There is no single “official” number, but most recent aviation and travel sources agree that the United States has a bit over 100 international airports as of 2025–2026, depending on how “international” is defined (customs facilities, scheduled overseas routes, etc.).

Why the numbers differ

Different organizations and writers count “international airports” in different ways:

  • Some counts include any airport with U.S. Customs and Border Protection facilities , even if it only handles occasional international flights or private jets. This can push the number into the hundreds.
  • Other estimates focus on commercial gateways with regular international passenger service , which is where the “over 100 international airports” figure comes from.
  • The U.S. has over 19,000 total airports , but only a fraction of these handle international traffic of any kind.

A helpful way to think of it: thousands of airports, a few hundred with some international capability, and a bit over one hundred that function as recognizable international gateways for travelers.

In practice, when people ask “how many international airports in US,” they usually mean these 100‑plus major and mid‑sized gateways where you can book direct or connecting flights to other countries.

TL;DR:
If you need a single, practical answer for “how many international airports in US,” you can safely say: just over 100 international airports nationwide.
