There are most likely no direct flights on the Kolkata — Mumbai route
Netaji Subhas Chandra Bose International Airport (CCU) is Kolkata’s main international gateway and typically functions as the city’s full-service hub, handling long-haul and regional flights alongside domestic connections. Full-service carriers such as Air India and Vistara and budget operators like IndiGo commonly operate here, so fares can range from budget-friendly to premium depending on carrier and route. The airport sits about 17–18 km from the city center; taxis and app-based cabs usually take 30–60 minutes depending on traffic, while prepaid airport taxis and shared cabs are common options with fares typically between INR 300–700. There’s also an airport metro link under development to improve connectivity. Pros: comprehensive services, several lounges and international facilities; cons: can be busy and subject to Kolkata’s peak-hour congestion, so allow extra travel time. Kolkata’s older domestic terminal (now integrated within the main airport complex) historically served short-haul and low-cost domestic flights and still hosts many regional services; it usually caters to quick-turnaround carriers and regional schedules. Typical airlines include IndiGo and SpiceJet, with fares often perceived as more economical on domestic sectors. It’s roughly the same distance to the city center as the international terminal, with similar transport options—prepaid taxis, ride-hail cars and occasional shuttle services—taking around 30–60 minutes and commonly costing in the INR 250–600 range depending on service and traffic. Pros: frequent domestic connections and efficient check-ins for short trips; cons: can feel crowded during domestic peaks and offers fewer premium amenities than some larger international terminals.

It’s located about 25–30 minutes from south Mumbai by road (roughly 15–20 km), though travel times can stretch considerably in peak traffic; taxis, app-based cabs and prepaid airport taxis are common, with fares typically varying by route and time. The airport is connected to the city by the Mumbai Metro’s Line 3 (partial sections) and suburban train networks near terminals, offering quicker options during rush hours. Pros: extensive international connections, wide amenities and good onward transport; cons: can be busy, security queues and traffic delays are common during peak periods.
