FAQs for booking flights from Louisville to London

  • Will I pay extra for pre-selecting a seat when flying from Louisville International Airport, Kentucky, to London?

    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. The seat assignment is usually done at check-in unless you're traveling in the Economy Light cabin, in which case you'll pay a small fee for pre-selection.

  • Will my child get a reduced ticket price from Louisville International Airport (SDF) to London?

    All children aged 0 to 23 months sit on adult laps throughout the flight. Older kids up to age 12 are charged less by KLM Airlines. So, when booking your flight through KAYAK, indicate your child's age to see an automatic fare reduction.

  • Are there airlines with fully flat beds on this route?

    The Business class cabin by British Airways has lie-flat seats. With a Club World ticket, you'll enjoy flying in a seat that extends into a flatbed (6 feet long). These seats have lumbar support and a fully adjustable headrest. You may request bedding for added comfort.

  • Can I travel to London with other animals besides cats and dogs?

    Always check the airline's pet policy before planning a trip with any animal. Iberia Airlines allows pets in the passenger cabin (18lb or less, including the cage), in the hold as extra baggage, or cargo compartment. You may bring a cat, dog, tortoise, fish, and bird accompanied by the correct documents. They, however, do not permit dangerous breeds and brachycephalic animals.

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.

Great crew - old style upper class seats on the older fleet now feels dated

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

The crew was excellent as ever on Virgin. The special meal was poor unfortunately. More significantly when we arrived at Manchester Airport there was no air bridge provided and we had to exit the plane down a rickety stair case. This is unacceptable for a transatlantic flight. Whilst I understand that this is the airport’s fault at the end of the day the airline is responsible for our transportation and needs to do something.

Super friendly and helpful staff, from check-in desk to cabin crew.

Following a paid seat upgrade for enhanced comfort, I encountered an unacceptable odor in my assigned area. It took three hours for the crew to relocate me, and the replacement seat was unacceptably close to the lavatory, offering no improvement.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

I did not fly by vergin atlantic from bangalore to vasco da gama

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.

Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,
