Lucknow to Kolkata links two major eastern and northern cities, but non-stop capacity is modest. In 2026 IndiGo is the only carrier flying it non-stop, typically with about two departures a day. If those do not suit, you can connect on a 1-stop with Air India or Akasa Air, usually via Delhi. For most travellers the IndiGo non-stop is the obvious choice when the timing works, with the connections as a fallback.
The distance is roughly 950 km, covered non-stop in about 1 hour 45 minutes, or close to 1h 50m gate to gate. A 1-stop itinerary typically runs 4 to 6 hours depending on the layover. Both cities sit on Indian Standard Time, so there is no time-zone change — your arrival time is simply departure plus flying time.
Demand peaks around Kolkata's festival calendar — Durga Puja above all — and the winter travel season, when fares firm up well in advance. On a short non-stop route with limited daily capacity, booking two to four weeks ahead is wise, more for Puja and the winter holidays.
| Period | Demand | Fare tendency |
|---|---|---|
| Apr–Jun | Moderate (heat) | Often the best value |
| Jul–Sep (monsoon) | Lower | Good deals midweek |
| Oct (Durga Puja) | Very high | Book well ahead |
| Nov–Jan (winter) | High | Festive & winter peak |
Fares move with availability, so treat any quote as indicative and confirm the live price before booking.
Stay flexible by a day or two — the cheaper of IndiGo's two daily non-stops is often the less convenient one. Compare the non-stop against a 1-stop via Delhi; occasionally the connection is cheaper if you have time to spare. Book ahead of the Durga Puja rush, set a price alert, and avoid buying on the travel day itself. FlightGPT shows IndiGo's non-stops alongside Air India and Akasa connections in one view so you can judge whether the direct is worth the premium.
With two non-stops a day, your realistic windows are morning and later in the day. A morning departure from Lucknow lands you in Kolkata with the afternoon free — useful for business or for connecting onward to the north-east. If you are connecting via Delhi, an early start gives the most comfortable layover and avoids a very late Kolkata arrival. Check the full timing before booking a connection.
Business travellers: the IndiGo non-stop is the time-efficient pick; book early as capacity is limited and Puja season fills fast. Families: the under-two-hour non-stop is far kinder than a 5-hour connection, especially with children — pick a daytime flight. Students & budget flyers: both cities have large student populations; mid-week non-stops or a well-timed 1-stop via Delhi usually give the lowest fares.
Lucknow (LKO): Chaudhary Charan Singh International Airport handles domestic flights from its terminals, with a newer integrated terminal (T3) expanding capacity — check your boarding pass for the correct terminal. Kolkata (CCU): Netaji Subhas Chandra Bose International Airport operates from a single large integrated terminal serving both domestic and international flights, so there is no terminal transfer to worry about on arrival.
At Lucknow: the airport at Amausi is about 15 km from the city centre, roughly 30–40 minutes by app cab, prepaid taxi or auto. At Kolkata: the airport at Dum Dum is around 17 km from the centre; app cabs, prepaid taxis and the new metro link (Orange Line, extending towards the airport) serve the city. App cabs are the most reliable door-to-door option at both ends, especially with luggage.
Domestic economy generally allows 15 kg checked plus a 7 kg cabin bag, but the cheapest fare buckets are often hand-baggage-only — check what your fare includes before paying. Excess baggage is far cheaper pre-paid online than at the counter. As IndiGo operates the non-stops here, see IndiGo baggage for the most likely allowance on this route.
Lucknow winters (December–January) bring morning fog that can delay early departures — book a later slot in peak fog season if you can. Kolkata is hot and humid much of the year, with heavy rain in the June–September monsoon and the risk of a Bay of Bengal cyclone in the shoulder months. If you are travelling in fog or monsoon season, keep your contact details current so the airline can reach you about any schedule change.
With only two non-stops a day, the convenient one books out first — especially around Durga Puja. Lock it in early once your dates are firm. If it is full or badly timed, use FlightGPT to compare it against Air India and Akasa connections via Delhi; sometimes a 1-stop is cheaper and only a couple of hours longer.
Yes. IndiGo flies the route non-stop, typically with about two departures a day. If those do not suit, you can connect on a 1-stop via Delhi with Air India or Akasa Air.
The non-stop takes about 1 hour 45 minutes over roughly 950 km. A 1-stop connection usually runs 4 to 6 hours depending on the layover.
IndiGo operates the non-stops. Air India and Akasa Air offer connecting service, usually via Delhi. Go First and Jet Airways no longer operate, and Vistara has merged into Air India.
IndiGo runs around two non-stop departures a day. Beyond those, the remaining options are 1-stop connections, so it pays to book the direct early.
Domestic flights operate from Lucknow's terminals, with a newer integrated terminal (T3) in use. Check your boarding pass for the correct terminal before you travel.
Domestic economy is generally 15 kg checked plus a 7 kg cabin bag, though the cheapest fares may be hand-baggage-only. Check your fare and pre-pay any excess online to save money.
Yes. Web check-in opens 48 hours before departure on most carriers and closes 1–2 hours before. It lets you pick a seat and avoid the counter queue.
Yes. Under DGCA rules, if the airline cancels your flight you are entitled to a full refund including taxes and fees, or a free re-booking on an alternative flight, at your choice.
It can. December–January mornings in Lucknow often bring fog that delays early flights. If you can, book a later slot in peak fog season and keep your phone reachable for rescheduling alerts.
Some carriers allow pets in the cabin or hold on domestic routes, subject to weight, carrier policy and advance booking. Seats are limited, so contact the airline well before travel rather than at the airport.
Infants under two travel on an adult's lap at a reduced fare and do not get a seat. Carry date-of-birth proof and request bassinet seats early, as they are limited.
Prices are often similar, but the base fare is set by the airline. FlightGPT compares airline and OTA prices side by side so you can find the cheapest route to the same seat.
