Washington to London is a route of government, policy, defense and consulting: delegations, law firms, think tanks and corporate leaders traveling between two capitals. Private flights from the capital usually leave from Washington Dulles (IAD), which has business-aviation facilities and is convenient for northern Virginia. In London, Luton, Farnborough and Biggin Hill each suit a different part of the city; Farnborough is popular for the West End and the M3 corridor.

Dulles is one of the country's main business-aviation airports: the 5th-busiest US private-jet airport in 2025 (ARGUS). Private flights do not use the airline terminal; passengers check in at an FBO on the field, such as Signature or Jet Aviation, drive up to the ramp and board there.
For a transatlantic trip that matters on the way back: the FBO facilities at Dulles include US Customs and Border Protection processing for international arrivals, so a flight from London clears customs at the private terminal rather than in the international arrivals hall. The operator files the passenger information before departure, as for any international flight.
If you are coming from Maryland or Baltimore, ask us to quote from BWI as well. For other capitals-to-London options, compare New York to London, and for the short hop to Manhattan see New York to Washington, DC.
