About the Kolkata → Delhi route
Kolkata to Delhi is one of India's workhorses — a sub-two-hour hop covering 1,312 km that carries a heavy mix of government officials, corporate travellers, and families visiting relatives spread across both cities. IndiGo (6E) dominates frequency on this route, which tells you something about who's flying it: people who want to get there, not people who want an experience. Flight time runs around 1 hour 33 minutes, which is just long enough to eat whatever passes for a snack and not much else. It's domestic India at its most functional.
Why travel from Kolkata to Delhi?
Delhi rewards the trip in ways that take a few visits to fully appreciate. Old Delhi alone — specifically the lanes around Chandni Chowk — is worth the fare, whether you're chasing Mughal architecture, street food that'll recalibrate your expectations, or both. Business travellers have obvious reasons: Delhi is the capital, and where the ministries and headquarters are, the flights follow. Family ties between Bengal and Punjab run deep historically, so plenty of passengers are doing the simple, unglamorous work of showing up for weddings and funerals and everything in between. And if you haven't eaten at a proper dhaba in Delhi, you've been eating the wrong food in the wrong city.

Practical tips for CCU → DEL
October through March is the sweet spot — cooler, drier, and generally cheaper to fly than the summer peak. That said, Delhi winters bring serious fog, and early morning departures out of DEL can stack up delays fast; mid-morning flights are lower risk. On arrival, the Delhi Metro's Airport Express line runs directly from Terminal 3 to New Delhi station in about 20 minutes and costs almost nothing compared to a cab. If you're flying IndiGo or SpiceJet (SG), check your baggage allowance before you pack — low-cost carriers on this route enforce limits strictly and the add-on fees sting. No visa complications for Indian nationals, obviously.
