Flights from Delhi to Kolkata
The Delhi–Kolkata corridor is one of India's busiest domestic trunk routes, connecting the national capital to the country's cultural and commercial hub in Bengal in a typical block time of around two hours over roughly 1,300 kilometres. IndiGo dominates frequency with its A320-family fleet, while Air India fields a mix of narrowbodies and occasionally an A321neo, and SpiceJet rounds out the meaningful capacity; JetLite operates marginally on the route. A practical note worth flagging: departures from Delhi use Terminal 2 or Terminal 3 depending on the carrier, so confirm your terminal before heading to Indira Gandhi International, as the two are not connected airside. On fares, midweek departures — particularly Tuesday and Wednesday — tend to offer softer pricing, and the leanest travel months are typically February through March and again in September, before the festive-season surge drives yields noticeably higher across the board.
