Heathrow is the world's most connected airport and the UK's primary international gateway, operating four active terminals — 2, 3, 4 and 5 — with British Airways based exclusively at Terminal 5, its largest terminal. Terminal 2, nicknamed the Queen's Terminal, serves as the exclusive London base for carriers including Lufthansa, United Airlines and Singapore Airlines, while Terminal 3 hosts a mix of major long-haul names like Emirates, Virgin Atlantic, Cathay Pacific and Qantas, and Terminal 4 is home to airlines such as Qatar, Air France, ITA Airways and Etihad. In 2025, Heathrow handled a record 84.5 million passengers, cementing its position as Europe's busiest airport, and it now serves around 230 destinations across more than 80 countries with over 80 airlines, making it a gateway to virtually anywhere in the world.
For those wanting a break in the sun, there are direct flights to Mediterranean favourites like Spain, Portugal, Italy and Greece, with routes to Mediterranean and Adriatic destinations continuing to grow year on year. Beyond Europe, long-haul options open up bucket-list trips too, from the USA and Caribbean to the Middle East and Southeast Asia, with new routes being added regularly such as Alaska Airlines' first-ever Heathrow service and the UK's only direct link to St Louis with BA. Whether it's a fortnight of guaranteed sunshine or a once-in-a-lifetime long haul adventure, Heathrow's sheer scale means there's rarely a destination it can't get you to.
