Kolkata (CCU) to Mumbai (BOM) is a major metro trunk route, so non-stop competition is healthy. IndiGo runs the most frequencies, with Air India, Akasa Air and SpiceJet filling out the schedule across the day. Because four carriers compete, fares stay relatively keen for a 1,650 km hop.
Almost everyone flies non-stop here — a 1-stop itinerary makes little sense on such a well-served route and only appears when the cheapest non-stops sell out. Disregard any old listings showing Go First or Jet Airways: both are defunct, and Vistara has merged into Air India.
The distance is about 1,655 km across central India. A non-stop takes roughly 2h 40m gate to gate, with around 2h 20m airborne. Westbound flights into Mumbai can run slightly longer when the airport is busy and aircraft hold before landing; the eastbound return to Kolkata is usually a touch quicker.
There is no shorter routing — the cities are diagonally opposite, so every flight tracks a similar central path. The only variable is taxi and holding time at congested Mumbai.
This route peaks around Durga Puja (Sep–Oct), Diwali and the December holidays, when Bengali travellers move in both directions. Summer (April–June) and the monsoon shoulder are usually softer.
| Period | Demand | Fare trend |
|---|---|---|
| Jul–Aug (monsoon) | Moderate | Often the best value |
| Durga Puja (Sep–Oct) | Very high | Peaks sharply for ~2 weeks |
| Diwali (Oct–Nov) | Very high | Dear; book well ahead |
| Dec 20 – Jan 5 | Very high | Highest of the year |
| Feb–Mar | Moderate | Steady, fair fares |
Two to five weeks ahead is the sweet spot for everyday travel. For Durga Puja, Diwali and the year-end peak, book six to eight weeks out — these sell out fast in both directions.
On a four-carrier route, a little flexibility goes a long way:
FlightGPT shows the live non-stop fares across all four carriers for your dates so you can see at a glance who is cheapest.
Frequencies are spread right across the day. Early-morning departures (06:00–09:00) are ideal for same-day business and arrive in Mumbai mid-morning. There is a strong evening bank for those finishing a Kolkata work day, plus genuine late-night and red-eye options that are often the cheapest seats on the route.
If you have a connection or commitment in Mumbai, favour a morning non-stop — it leaves slack against the city's notorious evening congestion and weather delays.
Business travellers: Pick a morning non-stop and a fare that allows date changes. With 13-plus daily flights, you are rarely stuck if plans shift, but the convenient mid-morning slots fill first.
Families: Daytime departures suit children best; book check-in bags online to avoid counter charges. Mumbai T2 is large and modern, with plenty of food and feeding space airside.
Students: The red-eye and very early IndiGo, Akasa and SpiceJet flights, booked two to four weeks out, are the cheapest. Travel cabin-only and keep a valid photo ID ready for check-in.
Kolkata (CCU): Netaji Subhash Chandra Bose International has a single Integrated Terminal handling all domestic and international departures, so there is no terminal confusion at this end.
Mumbai (BOM): Most flights on this route use the modern Terminal 2; a handful operate from Terminal 1. The two are several kilometres apart with a free inter-terminal shuttle, so confirm your terminal on the boarding pass before heading out.
In Kolkata: The airport is in Dum Dum, roughly 16 km from the centre. App cabs and the airport's prepaid taxis are the usual choice; the Metro's extension towards the airport has improved access, but allow for traffic on the VIP Road in peak hours.
In Mumbai: Reaching the city from T2 can be slow in rush hour — budget at least 90 minutes from south Mumbai or the western suburbs in the evening. App cabs, prepaid taxis and the Metro (with a short connecting hop) all serve the airport.
The standard domestic free allowance is 15 kg check-in and 7 kg cabin on IndiGo, Akasa Air and SpiceJet; Air India usually allows 15 kg in economy as well. Saver fares on the low-cost carriers may not include any check-in baggage, so verify before you pay. Pre-paid excess online is much cheaper than buying it at the airport. The IndiGo baggage page lists the current weights and fees.
Both ends share the south-west monsoon (June–September), and heavy rain or a cyclone in the Bay of Bengal can disrupt Kolkata departures, while Mumbai sees its own monsoon delays — keep buffers in this window. Winter fog is rarely a problem on this route. Kolkata's October–March cool season is the most comfortable time to fly; summer is hot and sticky at both ends. Always check your flight status during the rains before leaving for the airport.
Kolkata to Mumbai is busy enough that you almost never need a 1-stop fare — there are usually 13 or more non-stops a day. The cheapest seats are the red-eye and very early-morning flights booked two to five weeks out, ideally cabin-only. Lock in early for Durga Puja, Diwali and the year-end peak, when both directions sell out. FlightGPT compares all four carriers live so you can grab the cheapest non-stop for your exact slot.
A non-stop takes about 2h 40m gate to gate, with roughly 2h 20m in the air. It is a direct trunk route, so few people fly connecting.
IndiGo, Air India, Akasa Air and SpiceJet all operate non-stops. Go First and Jet Airways are defunct, and Vistara has merged into Air India.
Around 13 to 16 non-stop departures a day, spread from early morning to late night, making it one of the country's busier routes.
All domestic flights leave from the single Integrated Terminal at Netaji Subhash Chandra Bose International, so there is no terminal confusion.
Most flights use Terminal 2; a few use Terminal 1. The two are several kilometres apart, so check your boarding pass.
The monsoon and summer shoulder months are usually the best value. Durga Puja, Diwali and the Dec 20–Jan 5 window are the dearest.
Two to five weeks ahead is the sweet spot for everyday travel; six to eight weeks for Durga Puja, Diwali and the year-end peak.
Typically 15 kg check-in and 7 kg cabin on IndiGo, Akasa and SpiceJet; Air India also allows 15 kg in economy. Saver fares may exclude check-in baggage.
Yes. All four carriers open web check-in 48 hours before departure, letting you choose seats and skip the counter if you have no bags to drop.
It can. Heavy rain or a Bay of Bengal cyclone may disrupt Kolkata departures, and Mumbai has its own monsoon delays. Check your status before leaving in June–September.
Yes. Under DGCA rules, if the airline cancels and cannot offer a suitable alternative, you get a full refund including taxes and fees, whatever the fare type.
Air India permits small pets in the cabin or as checked cargo on domestic flights with prior approval; IndiGo, Akasa and SpiceJet generally do not carry pets in the cabin. Always confirm in advance.
Yes. Infants under two travel on an adult's lap for a nominal fare. Carry age proof and request a bassinet row in advance where available.
Prices are usually close. FlightGPT compares the live non-stop fares across all four carriers so you can see who is cheapest for your dates and book without overpaying.
Rarely. With 13-plus daily non-stops, a connection only makes sense if the non-stops have sold out or a 1-stop fare is dramatically cheaper for flexible dates.
