Quick answer: Colombo to New Delhi distance at a glance
Flight distance from Colombo (CMB) to New Delhi (DEL) is 1,488 miles (2,395 km, 1,293 nm) great-circle using real OpenFlights coordinates, with an estimated nonstop time of 2h 59m and route type medium-haul regional. Coordinates are 7.18°, 79.88° → 28.56°, 77.10°, bearing 353° north from haversine formula.
Facts computed from OpenFlights — not estimated. See methodology below.
The great-circle distance from Colombo (CMB, Sri Lanka) to New Delhi (DEL, India) is 1,488 miles (2,395 kilometers, 1,293 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 (7.18°, 79.88° for CMB; 28.56°, 77.10° for DEL). A nonstop flight on this route is estimated to take about 2 hours and 59 minutes, assuming a typical cruise ground speed of 500 mph including climb-out and descent. The destination lies roughly north of the origin (initial bearing 353°), placing the midpoint of this route near coordinates (17.87°, 78.49°).
By route type, this is a medium-haul regional flight. Medium-haul routes are usually nonstop on narrowbody aircraft such as the Airbus A320 or Boeing 737 — a 1.5–3 hour flight that rarely needs a connection. 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 134 kg CO₂ in economy, and the route difficulty score is 3/10.
Great-circle route from Colombo (CMB, 7.18°, 79.88°) to New Delhi (DEL, 28.56°, 77.10°). 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 (17.87°, 78.49°) 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 (1,488 mi), kilometers (2,395 km, conversion factor 1.60934), and nautical miles (1,293 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, bearing 353°) 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 CMB → DEL
At 1,488 miles this sits in the narrowbody sweet spot, which usually means frequent nonstops and competitive fares on this medium-haul regional route.

Colombo to New Delhi — quick answers
How far is Colombo from New Delhi by plane?
The nonstop flight distance from CMB (Colombo) to DEL (New Delhi) is 1,488 miles (2,395 km, 1,293 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 Colombo to New Delhi?
Estimated nonstop flight time is 2 hours and 59 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 CMB to DEL a short, medium, or long-haul flight?
This is a medium-haul regional flight (1,488 miles). Medium-haul flights are usually nonstop on narrowbody aircraft like the A320 or 737 with standard economy service. Flight categories follow industry distance bands that predict aircraft type and service level, so you can anticipate cabin options and connection likelihood.
