Quick answer: New Delhi to Lucknow distance at a glance
Flight distance from New Delhi (DEL) to Lucknow (LKO) is 263 miles (423 km, 229 nm) great-circle using real OpenFlights coordinates, with an estimated nonstop time of 45m and route type short-haul domestic. Coordinates are 28.56°, 77.10° → 26.76°, 80.89°, bearing 117° south-east from haversine formula.

The great-circle distance from New Delhi (DEL, India) to Lucknow (LKO, India) is 263 miles (423 kilometers, 229 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 (28.56°, 77.10° for DEL; 26.76°, 80.89° for LKO). A nonstop flight on this route is estimated to take about 45 minutes, assuming a typical cruise ground speed of 500 mph including climb-out and descent. The destination lies roughly south-east of the origin (initial bearing 117°), placing the midpoint of this route near coordinates (27.66°, 78.99°).
By route type, this is a short-haul domestic flight. Short-haul routes are typically served by narrowbody jets and regional turboprops, and nonstop service is common between major cities. The destination's solar time zone is 0 hour the same as the origin (see our time zone tool for the full breakdown). Estimated carbon footprint per passenger is about 24 kg CO₂ in economy, and the route difficulty score is 1/10.
Great-circle route from New Delhi (DEL, 28.56°, 77.10°) 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 (27.66°, 78.99°) 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 (263 mi), kilometers (423 km, conversion factor 1.60934), and nautical miles (229 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 (south-east, bearing 117°) 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 DEL → LKO
At 263 miles this is a train-or-plane decision — compare door-to-door time, not just air distance. Where rail exists on the corridor, it often beats flying once airport security time is counted.

New Delhi to Lucknow — quick answers
How far is New Delhi from Lucknow by plane?
The nonstop flight distance from DEL (New Delhi) to LKO (Lucknow) is 263 miles (423 km, 229 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 New Delhi to Lucknow?
Estimated nonstop flight time is 45 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 DEL to LKO a short, medium, or long-haul flight?
This is a short-haul domestic flight (263 miles). Short-haul routes are typically flown by narrowbody jets and regional aircraft with frequent nonstop service. Flight categories follow industry distance bands that predict aircraft type and service level, so you can anticipate cabin options and connection likelihood.
