About the Delhi → Kolkata route
Delhi to Kolkata is one of India's workhorse domestic routes — about 1,312 km, done in roughly an hour and thirty-three minutes, and operated by pretty much every major Indian carrier worth mentioning: IndiGo (6E), Air India (AI), SpiceJet (SG), and Air India Express (IX). It's a mixed crowd in the cabin. You'll find Bengali families heading home, corporate travelers shuttling between the two largest cities of northern and eastern India, and a fair number of tourists who've figured out that Kolkata rewards the curious. Nobody's crossing an ocean here, but don't sleep through it either.
Why travel from Delhi to Kolkata?
Kolkata earns its reputation through specifics, not superstition. The city's colonial architecture around Dalhousie Square (now Binoy-Badal-Dinesh Bagh) is genuinely unlike anything in Delhi — slower, more layered, slightly melancholy in the best possible way. For food travelers, this is a serious pilgrimage: mishti doi, kati rolls done properly, and fish preparations that Bengali home cooks will insist Delhi restaurants have never replicated correctly. There's also Durga Puja, which transforms the city every autumn into something you have to see once. Business travelers come for the port, the financial sector presence, and Kolkata's growing startup ecosystem. Family visits drive a huge share of bookings year-round — the Bengali diaspora in Delhi is substantial.

Practical tips for DEL → CCU
October through February is the sweet spot — cooler, dry, and fares tend to be reasonable outside the Durga Puja rush (book early for that window). Monsoon runs June through September; flights operate fine but expect delays. At CCU, the airport is modern and efficient, but the taxi queue can be slow — the prepaid cab counter inside arrivals is worth the short wait. The metro extension now connects Netaji Subhas Chandra Bose International to the city, which is genuinely useful. If you're flying IndiGo or SpiceJet, check your baggage allowance before packing — carry-on limits are enforced here.
