Distance guide covering 52+ routes across 12 cities in India. Includes domestic and international connections with flight times and driving distances.
India is home to 12 major cities in our database, including Delhi, Kolkata, Mumbai, Bangalore, Chennai and more. The largest city by population is Delhi with approximately 16,787,941 residents, located in the North India region.
Within India, there are 27 domestic routes connecting cities across the country. The shortest domestic route is Pune to Mumbai at 120 km, while the longest is Kochi to Delhi at 2,089 km.
India also connects to 25 international destinations worldwide. Whether you're planning domestic travel or international flights, this comprehensive distance guide provides all the information you need. All distances are calculated using the Haversine formula for maximum accuracy.
For travelers within India, shorter routes under 500 km are often well-suited for driving or train travel. Routes between 500-2,000 km offer a choice between driving and flying, while anything over 2,000 km is typically best served by air travel. Read our guide on estimating travel time for more detailed planning advice.

25 routes connecting India to cities worldwide, from 413 km to 12,538 km.
India's aviation and ground network shapes how the 52 routes on this page actually feel in practice. The flag carrier Air India handles most long-haul departures, while low-cost players such as IndiGo, Vistara, SpiceJet dominate short-haul leisure traffic. The primary international gateway is Delhi (DEL) and Mumbai (BOM), which also acts as the natural connection point for travelers using one-stop routings to save 20–40% on long-haul fares.
For shorter trips, ground transport in India is built around the world's fourth-largest rail network — IRCTC operates Vande Bharat semi-high-speed and Rajdhani long-distance services. On corridors under roughly 700 km, door-to-door rail travel is often faster than flying once airport security and transfers are factored in — a calculation worth running before booking domestic flights inside India.
Of the 52 routes covered here, the breakdown is 8 under 500 km, 17 between 500 and 1,500 km, 24 between 1,500 and 5,000 km, 2 between 5,000 and 10,000 km, 1 over 10,000 km. That mix is why a single travel-time rule never works for India: a typical traveler will encounter everything from a 60-minute regional hop to a 12-hour ultra-long-haul flight, depending on destination.
The 12 cities in our database for India are anchored by Delhi — a metropolitan area of roughly 16.79 million people sitting at 28.70°N, 77.10°E. That position places much of India in a subtropical climate with hot summers and mild winters, which directly influences both the local travel calendar and how comfortable arrivals from very different latitudes will feel.
Domestic distances within India range from Pune to Mumbai at 120 km up to Kochi to Delhi at 2,089 km. The wider that range, the more critical it becomes to match transport mode to journey length — exactly what the routes table above is designed to help with.
Because of Earth's curvature, the great-circle distances shown on this page are not the same as flight paths drawn on a flat map. Routes between India and far-away destinations often track closer to the poles than people expect — read more in our guide on how the Haversine formula works.
India offers comparatively low travel costs — last-minute bookings can still be reasonable, but planning ahead unlocks the cheapest fares and best train seats.
Mid-week departures (Tuesday and Wednesday in particular) into and out of India are typically 20–30% cheaper than Friday and Sunday flights on the same routes. Red-eye and very early-morning departures usually save another 10–15%. Budget carriers serving India apply strict carry-on rules and unbundled fares, so packing light remains the single biggest lever for keeping total trip cost low.
For multi-city trips inside India, compare the cost of a single open-jaw flight plus ground transport against multiple point-to-point flights — on routes with strong rail service, the rail-and-fly combination usually wins on both price and total door-to-door time.
Under 500 km: ground transport — driving, coaches, or the rail services described above — is usually competitive with flying door-to-door once airport overhead is included. This band covers many of the shortest routes on this page.
500–1,500 km: the choice gets interesting. In India, the high-speed rail network often beats flying door-to-door even at the upper end of this band, particularly if you can travel city-centre to city-centre.
Over 1,500 km: flying becomes the obvious choice. The 25 international routes from India above 1,500 km on this page are essentially flight-only journeys; ground alternatives exist only on a handful of specialist sleeper trains or long-distance coaches and aren't time-competitive.
Whichever mode you pick, use the calculator on this site to confirm exact great-circle figures, then add 20–40% for actual driving distance and 30–60 minutes per direction for airport overhead.

We cover 12 cities in India, including Delhi, Kolkata, Mumbai, Bangalore, Chennai and 7 more.
The longest domestic route is Kochi to Delhi at 2,089 km.
There are 25 international routes connecting cities in India to destinations worldwide. The shortest international route is Lahore to Delhi at 413 km.
All distances use the Haversine formula for great-circle distance — the shortest path between two points on Earth. Flight times assume 800 km/h cruising speed plus 30 minutes for takeoff/landing. Driving times use 80 km/h average with a 30% road routing factor.
