United Kingdom

The United Kingdom is Europe's largest aviation market and a major global connecting hub. London alone has six airports handling over 180 million passengers annually, making it the world's busiest city airspace.

Heathrow (LHR) is the UK's primary international gateway—Europe's busiest airport and the main hub for British Airways. For transatlantic travelers, Heathrow offers the most connections to North American destinations of any European airport.

The UK's geographic position makes it a natural transit point between North America and Europe, the Middle East, and beyond. Low-cost carriers have also made the UK accessible from across Europe, with Ryanair and easyJet operating extensive networks from secondary airports.

Off-Season (November-March)

Cheapest flights, but cold and dark (sunset 4pm in December). Christmas markets in December draw visitors. Good for: London theater, indoor attractions, avoiding crowds.
