Cheap flights London to Las Vegas

February is when fares on this route sit at their lowest, and the price calendar shows it: the months either side of it, from late autumn through spring, are worth comparing first. Summer and the run-up to Christmas are the expensive stretches, when both London and Las Vegas fill up with holiday traffic. Midweek departures usually cost less than weekend ones. Watch the calendar for two things: New Year in Las Vegas, which lifts fares on both sides of the Atlantic, and British school holidays, which raise prices on departures from all five London airports. If your dates are flexible, book a few months ahead for February and check the calendar as it moves.

Several carriers show up in searches for this route, and most of them are full-service names: British Airways and American Airlines on the transatlantic legs, with Swiss, Finnair, TAP Portugal and Iberia Express feeding into European hubs, and JetBlue Airways, WestJet and Republic Airways on the American side. Iberia Express and JetBlue Airways sell the kind of fare where the seat is the product and everything else is an add-on, so compare the total once bags and seats are in. Accesrail appears in some itineraries too. Because nothing on this route flies non-stop, the airline you book with is often not the one operating the long leg, so check who flies each segment before you commit.

Las Vegas is served by a single airport on this route: Harry Reid International, often shown as Harry Reid Intl when you search. It sits close to the Strip, so the ride to the resort corridor is short, and taxis, rideshares and hotel shuttles all leave from the terminal. What catches people out is the arrival itself — the US border queue can be long when several long-haul flights land at once, so allow room if you have booked a tight onward transfer. Keep your onward booking details to hand. If you are staying downtown rather than on the Strip, the transfer is longer, so decide where you are sleeping before you pick the flight.

Country facts: Wikidata

• Check which London airport your fare leaves from — the city spreads flights across five, and the journey to the wrong one can undo the saving.
• Every itinerary here involves a change of plane, so confirm whether the connection is on one ticket or two.
• If a low-cost carrier is in the mix, price the fare again with bags and seats added.
• Check that your passport and your US entry authorisation are valid for your dates before you book.
• February is when fares on this route sit at their lowest, so start your search there if your dates are open.
• Look hard at connection times — a short change at a big hub is tighter than it looks.
