Airlines & non-stop options on Delhi–Kolkata

Delhi to Kolkata is a heavily served trunk route with all the major Indian carriers competing. In 2026 you can fly it non-stop on IndiGo, Air India, Air India Express, Akasa Air and SpiceJet. Combined, they operate in the region of 20–28 non-stop flights a day.

IndiGo carries the largest share, but the breadth of choice means there is almost always a departure within an hour or two. Go First and Jet Airways no longer operate; Vistara has merged into Air India — disregard those names on stale listings.

Flight time, distance & routing

The cities are about 1,315 km apart. A non-stop flight is scheduled at roughly 2h 15m to 2h 25m, eastbound across the Gangetic plain. Eastbound flights sometimes benefit from a tailwind and can land a little early.

This is comfortably a two-hour-plus sector, so most flights serve a buy-on-board or included meal depending on the carrier and fare. Both ends are large airports, so build in time for taxi and, in winter, possible fog delays at Delhi.

Best time to book & seasonal fares

Demand on this route peaks sharply around the autumn festival season and winter, reflecting Kolkata's cultural calendar:

PeriodDemandWhat to expect
Sep–Oct (Durga Puja)Very highFestival peak to Kolkata; book weeks ahead
Dec–early JanHighWinter holidays and pleasant Kolkata weather
Apr–JunModerateHot in both cities; fares ease off
Jul–AugLowerMonsoon; usually the best value

The Durga Puja window is the single most important one to plan around — fares to Kolkata climb steeply and seats sell out, so book early if you are travelling then.

Getting your fare cheaper

Practical ways to pay less on Delhi–Kolkata:

Best departure windows

For value, the first flights of the day and the late-night departures (Delhi–Kolkata has flights running well past 10 pm) are generally cheapest. The 7–9 am business band and early-evening slots carry a premium.

For comfort, a morning departure lands you in Kolkata with the day ahead and dodges the higher fog risk that affects the very earliest winter Delhi departures — in December and January, a flight after the early-morning fog has lifted can be more reliable than the 6 am.

Advice by traveller type

Business travellers: morning and evening frequencies make a same-day return feasible. In winter, allow for Delhi fog and consider a flexible fare if your schedule is tight.

Families: a mid-morning flight is easiest with children and sidesteps the winter fog window. Pre-book seats together on this busy route, and pack snacks for the two-hour-plus sector.

Students and budget travellers: book early for the Puja and winter peaks, fly hand-baggage only on the cheapest carrier, and consider the late-night departures, which are often the lowest fares of the day.

Airports & terminals

Delhi (DEL): low-cost carriers — IndiGo, Akasa Air and SpiceJet — use Terminal 1 (T1), while Air India and Air India Express use Terminal 3 (T3). Check your terminal carefully; T1 and T3 are far apart and require a transfer if you go to the wrong one. (Some IndiGo flights also operate from T2 at peak times, so confirm on your boarding pass.)

Kolkata (CCU): Netaji Subhas Chandra Bose International operates from a single modern integrated terminal handling all domestic and international flights, so there is no terminal confusion at the Kolkata end.

Getting to and from the airport

In Delhi: the Airport Express Metro serves T3, and the wider Metro network plus app-cabs cover the city. For T1, app-cabs and the Magenta Line Metro are the usual options. Delhi traffic is heavy — leave a wide margin, especially in winter fog.

In Kolkata: the airport is at Dum Dum in the north of the city. App-cabs, the prepaid taxi counter and the iconic yellow Ambassador taxis all serve it, and Metro connectivity to the airport has been expanding. Allow extra time during evening traffic into central Kolkata.

Baggage allowance

Standard domestic economy is generally 15 kg checked plus a 7 kg cabin bag, varying by fare and airline. The cheapest fare families may include less or be hand-baggage only — check before you pay.

See IndiGo baggage for exact current figures. Pre-purchasing any excess online is far cheaper than paying at the airport counter.

Travel tips & weather

Delhi winter fog (December–January) is the biggest disruption risk on this route — morning flights can be delayed or diverted, so build in buffer time and avoid the very earliest departures if your plans are tight. Delhi summers (April–June) are extremely hot.

Kolkata is hot and humid much of the year, with a heavy monsoon (June–September). The most pleasant time to visit is the cool, dry winter (November–February), which is also why winter fares run high.

FlightGPT tip

Two things decide your Delhi–Kolkata trip: the date and the terminal. Around Durga Puja, fares to Kolkata spike — book well ahead. And at Delhi, double-check whether you're flying from T1 (IndiGo, Akasa, SpiceJet) or T3 (Air India, Air India Express), because they're far apart. FlightGPT compares all five carriers for your date so you can see the cheapest option and its terminal at a glance.

Which terminal at Kolkata?

When is the busiest time to fly to Kolkata?

Durga Puja (September–October) is the peak, when fares climb steeply and seats sell out, followed by the December–January winter season. Book early for those dates.

When should I book for the best fare?

Book several weeks ahead for the Puja and winter peaks. Off-peak, mid-week departures and the late-night flights are usually the cheapest.

Am I entitled to a refund if my flight is cancelled?

Yes. Under DGCA rules, if the airline cancels you are entitled to a full refund or a free alternative flight, and often compensation, even on a non-refundable fare.

Will Delhi fog delay my flight in winter?

It can. December and January mornings in Delhi are prone to fog, which delays or diverts flights. If your plans are tight, avoid the very earliest departures and keep a buffer.

What is the baggage allowance?

Usually 15 kg checked plus a 7 kg cabin bag, varying by fare and airline. Check your fare and the IndiGo baggage page for exact figures.

Can I do web check-in?

Yes. All carriers open web check-in 24–48 hours before departure — the fastest way to get a seat and skip queues at busy Delhi terminals.

Can I carry my pet on this route?

Some carriers permit pets in the cabin or hold on domestic flights, subject to advance booking, weight limits and health documents. Policies vary, so confirm with the airline.

Can I travel with an infant?

Yes. Infants under two travel on an adult's lap at a reduced fare. Carry age proof; cabin-baggage and stroller rules vary by airline.

Is it cheaper to book direct or via an OTA?

Headline fares are usually similar. Booking direct can ease changes and refunds; FlightGPT helps you compare all five carriers first, then book wherever suits you.
