The primary international gateway for Amsterdam is Amsterdam Airport Schiphol (AMS). It is the largest airport in the Netherlands and one of the busiest hubs in Europe, located just 9 kilometers (about 6 miles) southwest of the city center. Schiphol is unique because it operates as a "one-terminal" concept, meaning all gates are connected under one roof, making transfers and navigation relatively straightforward. From Schiphol, the most efficient way to reach central Amsterdam is by train, with direct services running every 10–15 minutes to Amsterdam Centraal station, taking roughly 15 to 20 minutes. While there are smaller regional airports like Rotterdam The Hague or Eindhoven, Schiphol handles almost all long-haul and major European carrier traffic destined for the Dutch capital.
