Major International Airports

Major international airports are the backbone of global air travel. These large airports handle scheduled international and domestic passenger service at high volumes, typically operating multiple runways and serving dozens of airlines with connections to destinations worldwide. Every airport in this list has an IATA code, confirming it handles regular commercial passenger traffic. Examples include London Heathrow (LHR), Los Angeles International (LAX), Dubai International (DXB), and Tokyo Haneda (HND). If you're booking a commercial flight, your departure and arrival airports will almost always be in this category.
