Las Vegas LAS to London Heathrow Flights (LAS to LHR): Nonstop Airlines, Flight Time and Travel Tips

Nonstop from the Strip to Heathrow

Las Vegas to London Heathrow is a nonstop route with strong demand from British visitors to Las Vegas and the wider Southwest. As of recent schedules, British Airways and Virgin Atlantic both fly nonstop between LAS and LHR. Frequencies vary by season, with more flights in the busy summer and winter holiday periods.

The two airlines belong to different partner groups: British Airways works with American in oneworld, and Virgin Atlantic shares seats with Delta. That means American or Delta flight numbers may appear on these nonstops, and both US airlines also sell one-stop itineraries through their hubs.

How long the flight takes

The route covers about 5,240 miles, crossing the Rockies, Canada and Greenland. Eastbound flights typically take about 10 hours. The return from London usually takes 10.5 to 11 hours, as it flies into the prevailing westerly winds.

Most flights leave Las Vegas in the afternoon or evening and land in London around midday the next day. The westbound return usually leaves Heathrow around midday and lands in Las Vegas in the afternoon, which makes the journey home easier on the body clock.

Departing from Harry Reid International

London flights normally check in at Terminal 3, which has the airport's international gates and customs facilities. Terminal 1 handles many domestic airlines and has its own check-in and security, so if you are being dropped off, go to Terminal 3.

There is no rail link to the airport. A taxi or ride-hail from the Strip usually takes 15 to 25 minutes, but traffic on Tropicana Avenue and around big events can add more. Some resorts run shuttle services, which are worth asking about at your hotel.

Arriving at Heathrow and into London

British Airways normally arrives at Terminal 5, and Virgin Atlantic at Terminal 3. With an approved ETA, most US passport holders can use the eGates.

The Heathrow Express takes about 15 minutes to Paddington, and the Elizabeth line runs straight through the West End and the City. The Piccadilly line is slower but direct to South Kensington and Leicester Square, which suits many hotels popular with visitors.

Eight hours of jet lag

London is eight hours ahead of Las Vegas for most of the year, and seven hours for a few weeks each spring and autumn, when the two countries change their clocks on different dates. Nevada observes daylight saving time, unlike neighbouring Arizona.

Las Vegas nights can make adjusting harder. If you have been staying up late on the Strip, try to shift your sleep earlier for a day or two before flying, then sleep in the second half of the flight. On arrival, stay outdoors in daylight and hold out until a normal London bedtime.

Choosing between British Airways and Virgin Atlantic

British Airways lands at Terminal 5 and suits travellers connecting onward to Europe or members of the oneworld programmes. Virgin Atlantic arrives at Terminal 3 and is popular with Delta loyalty members and with UK holidaymakers who book Virgin Holidays packages. Both offer premium economy and lie-flat business cabins on the aircraft normally used on this route.

If the nonstop dates do not suit you, one-stop itineraries through Los Angeles, Dallas, Chicago or New York can add flexibility, at the cost of a longer journey.

Starting from elsewhere in the Southwest

Las Vegas is the only nonstop gateway to London in Nevada, and it draws travellers from southern Utah, Arizona and southern California too. If you are coming from St George, Kingman or the California desert, driving to Las Vegas can be quicker than connecting through Los Angeles or Phoenix.

From smaller airports, a domestic flight into Las Vegas or another hub on the same ticket keeps your bags checked through to London and protects the connection if the first flight runs late. Connecting passengers can usually reach Terminal 3's gates without leaving security, using the trams that link the gate areas; check with your airline if you are unsure.

Entry requirements

US citizens do not need a visa for a short visit to the UK but must hold an approved Electronic Travel Authorisation (ETA) before boarding. Apply through the official UK government app or GOV.UK. Check GOV.UK for the rules that apply to other nationalities.

When to fly

The busiest periods are summer, the Christmas and New Year holidays and weeks around major Las Vegas conventions and events, when many UK visitors are travelling in both directions. Spring and autumn usually bring easier availability and milder weather in London.

What travellers get wrong

The most common slip is being dropped at the wrong terminal. Many domestic flights check in at Terminal 1, but London flights check in at Terminal 3, and each has its own security.

The other is underestimating the time change after late nights in Las Vegas. Planning a quiet first day in London helps more than any sleep aid.
