Mumbai–Kolkata is one of India's busiest east-west trunk routes, with non-stops from before dawn to late evening. Air India and IndiGo carry the most flights, with Akasa Air, Air India Express and SpiceJet adding more.
That gives you around twenty or more non-stops a day — easy to find a convenient time. Go First and Jet Airways no longer operate, and Vistara has merged into Air India, so ignore older listings showing them.
The cities are about 1,655 km apart. The non-stop is scheduled at roughly 2h 35m, with actual airborne time nearer 2h 25m once taxi and holding are removed. The eastbound routing crosses central India toward the Gangetic delta. Both cities are on IST, so there is no time change.
Demand spikes around Durga Puja, when travel to Kolkata surges, and through the pleasant winter season.
| Period | Demand | What to expect |
|---|---|---|
| Durga Puja (Sep–Oct) | Very high | Kolkata-bound seats fill first; book weeks ahead |
| Winter (Nov–Feb) | High | Peak Kolkata season; fog can disrupt morning arrivals |
| Monsoon (Jun–Sep) | Moderate | Softer fares; Mumbai rain delays possible |
| Summer (Mar–May) | Moderate | Mid-range fares outside school holidays |
We quote demand patterns, not specific rupee fares — always check the live price before booking.
With five carriers in play, comparison really pays:
The 6–9 am and 5–8 pm blocks are busiest and priciest, suiting business travellers who want a full day at either end. For value, the very first or last flight of the day usually costs less. In winter, avoid the very earliest arrivals into Kolkata when fog risk is highest — a mid-morning landing is more reliable.
Business travellers: the dense schedule supports same-day returns; book a morning out and evening back, and note your Mumbai terminal (T1 vs T2) for ground transfers.
Families: the non-stop is far easier than any connection for a 2.5-hour hop; mid-morning flights avoid pre-dawn starts.
Students and budget flyers: Air India Express, Akasa and SpiceJet often have the keenest fares; travel light, mid-week, and book the first or last flight of the day.
Mumbai's Chhatrapati Shivaji Maharaj International Airport (BOM) splits domestic flights by airline: Air India uses Terminal 2 (Sahar), while IndiGo, Akasa Air and SpiceJet use Terminal 1 (Santacruz). The terminals are about 4 km apart with a free shuttle — check your boarding pass.
Kolkata's Netaji Subhas Chandra Bose International Airport (CCU) at Dum Dum uses one large integrated terminal for domestic and international flights, so arrivals are straightforward — follow signs to the domestic baggage belts.
In Mumbai, app cabs, the prepaid taxi counter and the Metro/suburban rail serve both terminals; allow generous time in the city's traffic. In Kolkata, CCU is reached by app cabs, the airport prepaid taxi booth and city buses; the centre (Esplanade/Park Street) is typically 45–70 minutes depending on traffic. Check on the metro link to the airport as it opens up.
Saver fares on all carriers allow 15 kg checked plus one 7 kg cabin bag — see IndiGo baggage for current limits. Air India full-service fares may include more; Akasa, SpiceJet and Air India Express follow low-cost rules. Pre-buy extra weight online to avoid steep airport excess charges.
Kolkata is humid much of the year; pack light cottons outside winter. November to February is the pleasant, busy season. The monsoon (June–September) brings heavy rain to both cities and occasional Mumbai flooding, so allow buffer time. In December–January, early-morning Kolkata fog can delay arrivals — a mid-morning flight is the safer choice.
With five airlines and twenty-plus daily non-stops, Mumbai–Kolkata rewards comparison — let FlightGPT line up every carrier at once. Confirm your Mumbai terminal (Air India at T2, IndiGo/Akasa/SpiceJet at T1) so you head to the right building, and book a mid-morning Kolkata arrival in winter to dodge the fog.
