In 2026, more than 25 U.S. airports offer direct nonstop flights to London, primarily targeting London Heathrow (LHR) and London Gatwick (LGW). Major hubs with the highest frequency include New York (JFK and EWR), Los Angeles (LAX), Chicago (ORD), Washington D.C. (IAD), and Boston (BOS). Other significant gateways include Atlanta (ATL), Dallas (DFW), San Francisco (SFO), Miami (MIA), and Orlando (MCO). In recent years, direct service has expanded to "secondary" hubs such as Austin (AUS), Nashville (BNA), Cincinnati (CVG), and Portland (PDX). For travelers seeking a more boutique experience, flights from Newark (EWR) often provide the best "business class" availability. While Heathrow is the primary destination for legacy carriers like British Airways, American, and United, low-cost options and seasonal routes from Norse Atlantic and JetBlue often target Gatwick (LGW). It is a peer-to-peer "best practice" to check for flights into London Stansted (STN) if you are flying from the East Coast, as it occasionally hosts seasonal charter or budget-friendly connections not found at the larger hubs.
