About the Bengaluru → Kolkata route
BLR to CCU is a proper domestic short-haul — under two hours in the air, 1,546 km, and four airlines competing for your seat. IndiGo (6E) dominates frequency on this route, which keeps prices honest most of the year. You're looking at roughly 1 hour 49 minutes of flying, which means you're barely at cruising altitude before the descent begins. The passenger mix is interesting — a heavy chunk of IT professionals visiting family in Bengal, plus a solid stream of leisure travelers heading to one of India's most culturally distinct cities. Book smart and this route costs less than a nice dinner.
Why travel from Bengaluru to Kolkata?
Kolkata earns this trip on its own terms. The food alone — kathi rolls on Park Street, mishti doi from any neighborhood sweet shop, proper mustard-heavy fish curry — is worth the fare. Beyond eating, there's the colonial architecture around BBD Bagh, the Howrah Bridge at dawn before the crowds arrive, and the Indian Museum if you want genuine depth without the tourist theater. For travelers based in Bengaluru's tech corridor, Kolkata is also a major business hub with its own manufacturing and financial sectors. And for Bengali families spread across South India, this route is basically a lifeline — Durga Puja, weddings, and school holidays fill flights fast. It's a city that rewards slowing down.

Practical tips for BLR → CCU
October through February is the sweet spot — cool, dry, and festival season makes the city electric. Avoid June through August if humidity is your enemy. Fares dip noticeably on Tuesday and Wednesday departures. At CCU, the airport is modern and immigration clears quickly on domestic arrivals — just follow signs to baggage claim and skip the taxi touts inside. The Kolkata Metro Airport line connects to the city center for a fraction of the cab fare. If you're flying IndiGo or SpiceJet (SG), check your baggage allowance before you pack — 15kg checked limits catch people off guard every single time.
