Bengaluru to Kolkata is a major trunk route linking South India's tech hub with the East. IndiGo leads on frequency, with Air India, Air India Express and Akasa Air all flying non-stop. You'll find departures from early morning right through to late night.
The strong competition keeps fares reasonable for a 2.5-hour leg and gives you a wide choice of timings and baggage options. Disregard any listings for Jet Airways or Go First (both shut) or Vistara (now part of Air India).
The distance is about 1,560 km and scheduled block time is roughly 2 hours 35 minutes. There's no time-zone change — both cities run on IST despite the long east-west span.
All services fly non-stop on a north-easterly track across the Deccan and over central-eastern India. A meal or snack service operates on most carriers, with buy-on-board on the low-cost airlines.
This route blends business, migrant-worker and VFR travel, with sharp peaks around Durga Puja and other Bengali festivals when Kolkata-bound demand surges. Booking two to four weeks ahead is sensible; festival peaks need earlier planning.
| Period | Demand | Booking advice |
|---|---|---|
| Apr–Jun (summer) | Moderate | Book 2–3 weeks ahead |
| Jul–Sep (monsoon) | Lower | Best value outside festival dates |
| Oct (Durga Puja) | Very high | Book 4–6 weeks ahead |
| Nov–Jan (winter) | High | Book 3 weeks ahead |
Honest ways to trim the cost:
We never quote a guaranteed rupee fare — prices shift constantly. Compare live across sites on FlightGPT.
Early-morning departures land you in Kolkata before midday with a full day ahead and are the most punctual. Late-evening flights suit those finishing a Bengaluru workday. In winter (Dec–Jan), Kolkata can see early-morning fog that occasionally delays the first arrivals; a mid-morning slot sidesteps the worst of it.
Business: Morning departures give a workable same-day there-and-back, though the 2.5-hour leg makes an overnight more comfortable. Families: Mid-morning or early-afternoon flights avoid both the dawn rush and late-night fatigue with children. Students and budget flyers: Book well ahead, compare Akasa and Air India Express, and travel hand-baggage-only — the alternative is a 30-hour-plus train, so the flight is usually worth it.
Bengaluru (BLR): Kempegowda International. IndiGo domestic flights use Terminal 1; Air India and Air India Express domestic flights operate from Terminal 2. Confirm your terminal on the ticket — a free shuttle links the two every 10–15 minutes. Kolkata (CCU): Netaji Subhash Chandra Bose International has a single integrated terminal handling both domestic and international flights, so there's no terminal confusion on arrival.
Bengaluru: Kempegowda sits about 35–40 km north of the city; use Vayu Vajra airport buses or an app cab and allow 60–90 minutes in traffic. Kolkata: The airport at Dum Dum is roughly 15–17 km from the centre; app cabs and prepaid taxis take 30–50 minutes, and the metro's airport extension has been improving connectivity.

Kolkata is hot and humid for much of the year with a wet monsoon (Jun–Sep) and a brief, pleasant winter (Dec–Jan). Bengaluru stays mild thanks to its altitude.
