United Kingdom
America's favorite transatlantic hop — more nonstops than any other overseas city.
Getting there
London is the single most popular international destination for U.S. travelers, with nonstop service from over 25 American cities. Heathrow (LHR) handles most flights, while Gatwick (LGW) serves leisure routes with lower fares. Competition between British Airways, Virgin Atlantic, American, Delta, United, and JetBlue keeps prices sharp — if you know when and how to book.
