Quick answer: Riyadh to Lucknow distance at a glance
Flight distance from Riyadh (RUH) to Lucknow (LKO) is 2,123 miles (3,417 km, 1,845 nm) great-circle using real OpenFlights coordinates, with an estimated nonstop time of 4h 15m and route type long-haul international. Coordinates are 24.96°, 46.70° → 26.76°, 80.89°, bearing 79° east from haversine formula.

The great-circle distance from Riyadh (RUH, Saudi Arabia) to Lucknow (LKO, India) is 2,123 miles (3,417 kilometers, 1,845 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 (24.96°, 46.70° for RUH; 26.76°, 80.89° for LKO). A nonstop flight on this route is estimated to take about 4 hours and 15 minutes, assuming a typical cruise ground speed of 500 mph including climb-out and descent. The destination lies roughly east of the origin (initial bearing 79°), placing the midpoint of this route near coordinates (25.86°, 63.79°).
By route type, this is a long-haul international flight. Long-haul international flights require widebody aircraft (Boeing 777, 787, Airbus A350) and generally offer business- and first-class cabins alongside economy. The destination's solar time zone is 2 hours ahead of the origin (see our time zone tool for the full breakdown). Estimated carbon footprint per passenger is about 191 kg CO₂ in economy, and the route difficulty score is 5/10.
Great-circle route from Riyadh (RUH, 24.96°, 46.70°) to Lucknow (LKO, 26.76°, 80.89°). 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 (25.86°, 63.79°) 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 (2,123 mi), kilometers (3,417 km, conversion factor 1.60934), and nautical miles (1,845 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 (east, bearing 79°) 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 RUH → LKO
At 2,123 miles this is a widebody-distance route — aircraft type is worth prioritizing alongside price; a newer 787/A350 at 191 kg CO₂ is measurably more comfortable than an older aircraft on the same sector.

Riyadh to Lucknow — quick answers
How far is Riyadh from Lucknow by plane?
The nonstop flight distance from RUH (Riyadh) to LKO (Lucknow) is 2,123 miles (3,417 km, 1,845 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 Riyadh to Lucknow?
Estimated nonstop flight time is 4 hours and 15 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 RUH to LKO a short, medium, or long-haul flight?
This is a long-haul international flight (2,123 miles). Long-haul flights require widebody aircraft such as the 777, 787 or A350 and typically offer premium cabins. Flight categories follow industry distance bands that predict aircraft type and service level, so you can anticipate cabin options and connection likelihood.
