Quick answer: London to Las Vegas distance at a glance
Flight distance from London (LGW) to Las Vegas (LAS) is 5,240 miles (8,433 km, 4,553 nm) great-circle using real OpenFlights coordinates, with an estimated nonstop time of 10h 29m and route type ultra-long-haul international. Coordinates are 51.15°, -0.19° → 36.08°, -115.15°, bearing 311° north-west from haversine formula.

The great-circle distance from London (LGW, United Kingdom) to Las Vegas (LAS, United States) is 5,240 miles (8,433 kilometers, 4,553 nautical miles). This is the shortest path a plane could fly between the two airports, measured along the surface of the Earth using the haversine formula on the airports' real published coordinates (51.15°, -0.19° for LGW; 36.08°, -115.15° for LAS). A nonstop flight on this route is estimated to take about 10 hours and 29 minutes, assuming a typical cruise ground speed of 500 mph including climb-out and descent. The destination lies roughly north-west of the origin (initial bearing 311°), placing the midpoint of this route near coordinates (43.61°, -57.67°).
By route type, this is a ultra-long-haul international flight. Ultra-long-haul routes need dedicated long-range aircraft such as the Airbus A350-900ULR or Boeing 787-9 Dreamliner, and may include a technical refueling stop on the longest sectors. The destination's solar time zone is 8 hours behind the origin (see our time zone tool for the full breakdown). Estimated carbon footprint per passenger is about 472 kg CO₂ in economy, and the route difficulty score is 9/10.
Great-circle route from London (LGW, 51.15°, -0.19°) to Las Vegas (LAS, 36.08°, -115.15°). The dashed line is the shortest path between the two airports on the Earth's surface — the path a nonstop flight would follow. The midpoint at (43.61°, -57.67°) gives a sense of which region the flight overflies.
How this distance is calculated
TripRoute computes the great-circle distance between two airports using the haversine formula applied to each airport's published latitude and longitude from the public OpenFlights airports.dat dataset (the same data that powers airline route maps worldwide). The haversine formula accounts for the curvature of the Earth, so the result is the true shortest distance along the surface — not a straight line on a flat map. We express it in statute miles (5,240 mi), kilometers (8,433 km, conversion factor 1.60934), and nautical miles (4,553 nm, factor 0.868976). The estimated flight time assumes a ground speed of 500 mph including the climb and descent phases, which is a reasonable average for subsonic commercial jets — actual flight time varies with winds, routing, and the specific aircraft type. The compass direction (north-west, bearing 311°) is the initial great-circle bearing from origin to destination; the path curves slightly because of the Earth's curvature on long sectors.
TRWhen distance matters most for LGW → LAS
At 5,240 miles this is an ultra-long-haul — avoid tight connections; the carbon and jet-lag cost of a second takeoff outweighs a modest fare saving.

London to Las Vegas — quick answers
How far is London from Las Vegas by plane?
The nonstop flight distance from LGW (London) to LAS (Las Vegas) is 5,240 miles (8,433 km, 4,553 nautical miles), measured as a great-circle line across Earth's surface using the airports' published coordinates. This haversine calculation accounts for Earth's curvature and matches airline navigation charts; actual flown distance is slightly longer due to airways and winds.
How long does it take to fly from London to Las Vegas?
Estimated nonstop flight time is 10 hours and 29 minutes, assuming a typical jet cruise speed of about 500 mph including climb and descent. Gate-to-gate time is usually 20–35 minutes longer for taxi and air-traffic routing, and connecting itineraries add 1–4 hours depending on layover length and airport connection efficiency.
Is LGW to LAS a short, medium, or long-haul flight?
This is a ultra-long-haul international flight (5,240 miles). Ultra-long-haul routes need dedicated long-range aircraft and may require a technical stop on the longest sectors. Flight categories follow industry distance bands that predict aircraft type and service level, so you can anticipate cabin options and connection likelihood.
