Kolkata (India) has a population of 14,850,000 and is located in the East India region of Asia. As a major metropolis, it offers extensive international connections and diverse attractions.
Goa (India) has a population of 1,458,545 and is situated in West India, Asia. This city serves as an important regional hub with solid connectivity.
Choose this route if your priority is reaching Kolkata (India) — a city of 14,850,000 in the East India region of Asia. It is also the shorter option at 1,318 km, which translates to a 15 min flight-time saving and roughly 52 kg less CO₂ per passenger versus the alternative. Driving is realistic at this distance, with an estimated 1,713 km of road and a fuel cost band around $171 USD. The initial bearing is 119° (ESE), so a great-circle flight leaves Delhi heading roughly ESE.
This route is the right call if you are heading to Goa (India) — a city of 1,458,545 in the West India region of Asia. Even though it is the longer route at 1,522 km, it remains the obvious pick when Goa is the actual destination, when departure schedules from Delhi are more convenient, or when fares undercut the alternative. Driving is feasible — expect roughly 1,979 km of road and a fuel cost in the $198 USD range. Departing Delhi, the great-circle bearing toward Goa is 192° (SSW).

All distances on SnapDistance are calculated using the Haversine formula, which determines the great-circle distance between two points on Earth's surface. This gives the shortest possible distance over the globe, which is the measurement used for aviation and navigation. Actual travel distances by road or rail are typically 20-40% longer due to terrain, borders, and infrastructure routing. Flight times assume 800 km/h cruising speed with 30 minutes for takeoff and landing. Driving estimates use 80 km/h average speed with a 30% road distance factor.
