Airlines and non-stop options

Kolkata (CCU) to Delhi (DEL) is one of eastern India's busiest trunk routes, flown non-stop by IndiGo (the largest operator), Air India, Air India Express and Akasa Air. Between them they run roughly 20–28 non-stops a day, giving you a departure most hours from early morning to late evening. IndiGo owns the bulk of the timetable, so if your plans shift you can usually rebook onto one of its later services without a long wait. Note that Go First and Jet Airways no longer operate, and Vistara has merged into Air India — you'll only see the carriers listed above on this sector today.

Flight time, distance and routing

The route covers roughly 1,300 km and non-stop flights take about 2h 15m gate to gate, tracking north-west from the Bengal delta across the Gangetic plain to the capital. A handful of one-stop itineraries route via hubs such as Mumbai, Bengaluru or Hyderabad, but they add hours for no fare saving on most dates — on a route this well-served, the non-stop is almost always the sensible choice. Always filter for non-stop in the FlightGPT search so connecting flights don't clutter your results.

Best time to book and seasonal fares

Fares on Kolkata–Delhi track demand closely. The autumn festival window — Durga Puja in particular, when Bengalis travelling home and out of the city pack the route — is the standout peak, alongside Diwali, the Christmas–New Year break and the winter wedding season. Booking 2–4 weeks ahead is usually enough on a high-frequency corridor like this, but Puja and year-end dates reward booking earlier. The tiers below show relative demand, not quoted prices.

Getting your fare cheaper

To save honestly on Kolkata–Delhi: fly the red-eye or first-wave morning departures rather than the crowded mid-morning and evening business banks; choose a mid-week day (Tuesday or Wednesday) over Friday and Sunday; and travel cabin-bag-only to skip the checked-bag fee on the leanest saver fares. Avoid Durga Puja week unless you book it months out, and compare all carriers rather than defaulting to one. The genuine bargains tend to hide on the smaller operators' off-peak rotations, so check IndiGo, Air India, Air India Express and Akasa side by side in the FlightGPT search.

Best departure windows

With a departure most hours, which slot you pick matters as much as which day. The two daily peaks are the business banks — the early-morning push (roughly 6–9am) and the evening return (roughly 5–9pm) — which airlines price up first and discount last. The red-eye and very first morning flight are the quietest and usually cheapest, while the midday lull (around 11am–3pm) is the sweet spot for leisure travellers: softer fares, daylight flying and a calmer airport at both ends. One Delhi-specific caveat: the December–January fog season most often disrupts arrivals in the 4–9am slots, so a mid-morning landing into DEL is the safer bet in deep winter.

Advice by traveller type: business, family, student

Business travellers should buy flexibility, not the rock-bottom seat — the route's high frequency means a flexible/Flexi-style fare lets you roll to an earlier or later flight if a meeting over-runs, usually for a modest premium. Book through your company travel desk if you have one for negotiated fares and the GST invoice you'll need for input-tax-credit reclaim. Families should pre-book seats so you're seated together (unallocated economy seats are assigned at check-in and families are routinely split), carry an age-proof document for any infant, and on a 2h sector pack your own snacks rather than relying on paid meals. An infant under 2 travels on your lap for a nominal fee; a child of 2 or older needs a full-priced seat — Indian low-cost carriers give no real child discount, so don't expect one. Students should know the honest position: Air India, Air India Express and IndiGo run a modest student offer (roughly 10% off base fare plus about 10kg extra baggage), but only when you book direct on the airline's own app/website, for travellers 12+, with proof of full-time enrolment — it is not a half-price fare, and most saver fares carry no student discount at all. Booking ahead and flying cabin-only saves more for most students.

Airports and terminals

You depart Kolkata's Netaji Subhas Chandra Bose International Airport (CCU), which has a single modern integrated terminal — all carriers, domestic and international, use the same building, so there's no terminal confusion at the Kolkata end. You arrive at Delhi's Indira Gandhi International Airport (DEL), where IndiGo and Akasa Air use Terminal 1 and Air India and Air India Express use Terminal 3. Delhi's terminals are far apart with no airside link, so if you're connecting onward, confirm your arrival and departure terminals in advance and budget time for the landside transfer. Always check your boarding pass, as terminal assignments can change.

Getting to and from the airport

Kolkata (CCU). The airport sits in Dum Dum, north-east of the city centre, roughly 16–17 km from the BBD Bagh business district. App cabs and the airport prepaid taxi counter are the reliable options; allow extra time during evening peak traffic and the monsoon, when approach roads can flood. The Kolkata Metro's expanding network is progressively improving airport connectivity, but for now most travellers go by road. As a rule, leave 2 hours before a domestic departure.

Delhi (DEL). Which terminal you land at decides your transfer. The Airport Express (Orange Line) serves Terminal 3 (about 20 minutes to New Delhi station); for Terminal 1, the Magenta Line's dedicated 'Terminal 1–IGI Airport' station is a short covered walk from the building. There's no airside link between Delhi's terminals — the only inter-terminal connection is the landside DIAL shuttle — so never assume you can walk between them. App cabs and prepaid taxis work well; add buffer in the December–January fog window. See our route hub for more city guides.

Baggage allowance

Domestic economy fares include 15 kg checked plus one 7 kg cabin bag on IndiGo, Akasa Air, Air India and Air India Express; Air India's premium fares and elite tiers may allow more. The cheapest saver fares on some carriers are cabin-only, so confirm the checked allowance against your specific fare before you pay, and pre-purchase any excess online — airport per-kg charges are far steeper. For exact size limits and excess rates, see the IndiGo baggage, Akasa Air baggage and Air India baggage pages.

Travel tips

Kolkata's monsoon (June–September) brings heavy rain that can slow road transfers and occasionally disrupt schedules, so build in buffer time. At the Delhi end, the December–January fog season frequently delays early-morning arrivals, so a mid-morning landing is more reliable in deep winter. Web check-in opens 48 hours before departure on all carriers — use it to pick seats and skip the airport queue. Carry a valid government photo ID; foreign nationals fly on their passport. Both airports are busy, so allow about 2 hours before departure during peak rushes.

FlightGPT tip

The single biggest swing on Kolkata–Delhi is the Durga Puja calendar. If your dates fall anywhere near Puja (late September to mid-October), fares spike weeks in advance and the cheap inventory vanishes early — book as far ahead as you can, or shift your travel by a few days to land in the calmer shoulder either side. Outside that window, this is a high-frequency route where booking 2–4 weeks out and flying off-peak (red-eye, first morning or midday) reliably beats the business banks. Set a fare alert in the FlightGPT search and compare all four carriers on one screen rather than loyalty-booking — the cheapest operator changes by the day.

Web check-in opens 48 hours before departure on IndiGo, Air India, Air India Express and Akasa Air. Use it to choose your seat and skip the airport check-in queue; arrive about 2 hours before a domestic departure.

Will winter fog affect my Kolkata to Delhi flight?

Delhi's December–January fog season frequently delays early-morning arrivals into DEL. If you're travelling in deep winter, a mid-morning landing is more reliable than the 4–9am slots, which are most exposed to low-visibility delays.

Does the monsoon disrupt Kolkata flights?

Kolkata's monsoon (June–September) brings heavy rain that can slow road transfers and occasionally delay departures. Build buffer time into your airport transfer and allow extra margin if you have an onward connection at Delhi.

Can I get a refund if my flight is cancelled?

Yes. Under DGCA rules, if the airline cancels your flight you're entitled to a full refund (including statutory taxes and fees) or a free re-accommodation on an alternative flight. For passenger-initiated cancellations, the refundable amount depends on your fare type, minus any applicable airline cancellation fee.

Can I carry my pet on a Kolkata to Delhi flight?

Pet policies vary by airline and most have limited capacity, so you must book and confirm in advance. Air India accepts pets in cabin (small) and cargo subject to conditions; IndiGo and Akasa have restricted pet acceptance. Always check the specific carrier's current pet policy before booking.

How do I travel with an infant on this route?

An infant under 2 travels on your lap for a nominal infant fee; a child aged 2 or older needs a full-priced seat. Carry an age-proof document such as a birth certificate, as carriers can ask for it at check-in.

Is it cheaper to book direct with the airline or via an OTA?

Prices are often similar, but booking direct on the airline's own app or website is where student discounts and some promotional fares are available, and it can simplify changes and refunds. A metasearch like FlightGPT lets you compare carriers first, then book wherever the fare is lowest.

Do I need a visa or special document to fly Kolkata to Delhi?

No — this is a domestic flight, so no visa is required. Indian travellers carry a valid government photo ID; foreign nationals already in India fly on their passport. Allow about 2 hours before departure during peak rushes.
