    Virgin Atlantic allows you to select a seat from a seat map. Gold and Silver members can choose any standard seat when booking SDF-LHR flights without a charge.

KAYAK’s top tips for finding a cheap flight from Louisville to London

  • Most carriers operating flights from Louisville International Airport (SDF) to London Heathrow (LHR) have a single stopover. American Airlines stop at Boston Logan (BOS), O'Hare Intl Airport (ORD), or Charlotte Douglas Airport (CLT), while United connects via Dulles Airport (IAD). If you wish to land at London Gatwick (LGW), you might have two stopovers at Atlanta Airport (ATL) and John F. Kennedy Airport (JFK).
  • Suppose your physique prevents you from sitting in a single seat. You can get more personal space for better comfort while on the route SDF-IAD-FRA-LCY, often operated by Lufthansa. Consider reserving an empty adjacent seat with the airline. However, you can only pay the extra fee at the check-in counter on your departure date.
  • You only need a visa to fly to London if you plan to stay in the United Kingdom for over six months. You'll get a visa vignette or sticker on your passport at the airport's immigration office. To extend your business trip or vacation for another six months, complete the UK visa renewal form, pay the applicable fees, and book an appointment at any UKVCAS office for biometrics.
  • British Airways is one of the best airlines for wheelchair users. If you have a mobility issue, you can specify the type of assistance you need when booking your flight. Special assistance includes basic wheelchair assistance and full-service- luggage storage and retrieval, boarding and alighting the aircraft, and chair aid to move around the cabin.
  • Children through age 17 are automatically subject to unaccompanied minor protocols, and the standard unaccompanied minor fee is charged where applicable. With United Airlines, the service is available for kids between 5 and 14 and is optional for the age bracket 15-17. When booking tickets for kids traveling alone, inform the airline who will drop them off at SDF and pick them up from the arrival airport in London.
