Flights from Kolkata to Delhi
The Kolkata–Delhi corridor is one of India's busiest domestic trunk routes, covering roughly 1,300 kilometres with a typical block time of around two hours, making it a comfortable same-day connection between West Bengal's commercial capital and the national capital. IndiGo dominates frequency on this sector and typically deploys A320-family narrowbodies, while Air India and SpiceJet offer competitive alternatives, with Air India providing the only meaningful business-class product if you need a lie-flat or recliner option on a short hop. A practical note worth flagging: Delhi's Indira Gandhi International handles domestic arrivals at Terminal 2, separate from the international Terminal 3, so travellers connecting onward internationally should build in at least ninety minutes and confirm their departure terminal at booking. Fares tend to soften during the post-monsoon shoulder months of October and November, and mid-week departures on Tuesdays and Wednesdays often yield noticeably lower economy pricing than Friday or Sunday evening peaks.
