Cheap flights from London to Louisville

May is the cheapest month on this route, with mild weather in Kentucky and none of the summer crowds. Fares also appear for September, October, November, December and February, so autumn and early winter are worth watching if spring does not work for you. Weekday departures from Heathrow or Gatwick tend to be quieter and often cheaper than weekend ones. Skip the days around Thanksgiving and Christmas: transatlantic seats sell out early and connections through American hubs get tight. On a long-haul route like this, booking well ahead matters far more than it does on a short hop to Europe.

No airline flies London to Louisville non-stop, so every itinerary is a connection, and the airline mix shows it. Delta Air Lines, Virgin Atlantic, British Airways, American Airlines and United Airlines are the names you will see most, pairing a transatlantic leg with a domestic hop into Louisville International. Aer Lingus, Brussels Airlines, TAP Portugal, Scandinavian Airlines and Air Canada turn up when the routing runs through Dublin, Brussels, Lisbon, Copenhagen or Toronto instead. All of these are full-service carriers, so the difference is the connection, the cabin and what the fare includes. Check the baggage rules for the whole itinerary, not just the first flight.

Louisville International is the only airport serving the city, so every itinerary ends in the same place and there is no second airport to weigh up. Ground transport into the centre is the usual American mix of taxi, rideshare and local bus, and the rental car desks sit at the airport if you plan to drive on. Check what still runs at your arrival time, particularly if a late connection pushes you in after the evening. The real thing to watch is the connection itself: a short layover in a large hub is the most common reason a London to Louisville trip goes sideways.

Country facts: Wikidata

• Check which London airport your ticket leaves from — Heathrow, Gatwick, Luton, Stansted and London City are far apart.
• Allow a generous connection: with no non-stop service, a missed domestic hop in the States can cost you a day.
• Confirm baggage for the whole itinerary, as the transatlantic and domestic legs may be handled by different airlines.
• If you book the legs on separate tickets, a delay on the first is not the second airline's problem.
• Sort your ESTA or visa for the United States well before departure.
• Compare May, the cheapest month, against September, October, November, December and February before you commit.
