Kolkata to Patna flights — quick facts

Airlines and non-stop options

Kolkata (CCU)–Patna (PAT) is a short, well-served non-stop corridor dominated by IndiGo, which carries the overwhelming majority of traffic — roughly nine in ten bookings. Expect around three non-stops a day, though the exact count shifts with the season. Air India schedules can appear from time to time, but IndiGo is the workhorse here. Ignore any aggregator still listing Go First, Jet Airways or Vistara — Go First and Jet Airways no longer fly, and Vistara has merged into Air India. This is a busy business, family-visit and onward-connection route between the eastern metro and the Bihar capital.

Flight time, distance and routing

The distance is only about 460 km, so the non-stop takes roughly 1h 15m to 1h 20m gate-to-gate. It is a quick hop — you are airborne for barely an hour. There is no reason to take a connecting itinerary on this route unless a non-stop is sold out or badly timed; a one-stop would more than double your travel time for no benefit.

Best time to book and seasonal demand

Demand climbs around major festivals — especially Chhath Puja, when Bihar sees heavy inbound travel — and during holidays and the wedding season. Book early in the windows below.

PeriodDemandBooking advice
Oct–Nov (Durga Puja, Chhath, Diwali)Very highBook 4–6 weeks ahead
Dec–Jan (holidays, weddings)HighFares firm; mind Patna fog
Apr–Jun (summer travel)ModerateMore give on price

We never quote a fixed fare — even on a short route, prices move with demand and how early you book. Use the table as a demand guide only.

Getting your fare cheaper

Best departure windows

On such a short route any slot works, but in winter, prefer a late-morning or midday departure — Patna is prone to dense fog on December and January mornings, which delays or diverts early flights. Outside the fog season, an early-morning departure maximises your day in Patna. Evening flights are fine in fair weather and often a touch cheaper.

Advice by traveller type

Business travellers: The frequent IndiGo non-stops make a same-day return easy. Pick a midday flight in winter to dodge morning fog, and use web check-in to skip queues.

Families: A one-hour hop is comfortable with children. Pre-book seats together and carry essentials in cabin baggage. The short flight beats the long road or rail alternative.

Students and budget flyers: Book early and stay flexible on the slot. Off-peak and mid-week flights are cheapest, and cabin-only fares keep costs down on a route this short.

Airports and terminals

Kolkata (CCU), Netaji Subhash Chandra Bose International, operates from a single large integrated terminal for domestic and international flights. It is modern and well sign-posted; allow time to walk between gates at peak hours.

Patna (PAT), Jay Prakash Narayan International, has a single compact terminal close to the city centre — among the more central airports in India. It can get congested at peak times given its size and growing traffic, and it is notably fog-affected in winter, so build in a buffer during December and January.

Getting to and from the airports

At Kolkata: the airport is about 16–17 km from the centre, 45–75 minutes by road depending on traffic. App-cabs (Ola/Uber), pre-paid taxis and buses all serve it.

At Patna: the airport is very central — only around 5 km from the railway station and city core, often 15–25 minutes by road. Pre-paid taxis, app-cabs and autos are all available. The short transfer is one of the conveniences of flying into Patna.

Baggage allowance

Standard 2026 domestic economy allowances apply: most airlines give 15 kg checked plus 7 kg cabin. IndiGo, which operates most flights here, applies its standard limits; Air India typically allows more on its own metal. On such a short hop, cabin-only travel is easy and often saves money. See IndiGo baggage and Air India baggage for current limits.

Travel tips and weather

Both cities are hot and humid in summer with a heavy monsoon. The key seasonal factor is winter fog at Patna: dense fog on December and January mornings regularly delays or diverts flights, so avoid the earliest slots and keep a buffer for onward plans. The most comfortable months to visit Patna and Bihar are October to March. Carry light cottons for summer and a warm layer for winter mornings.

FlightGPT tip

Kolkata–Patna is a frequent, cheap non-stop hop, so the real wins are timing and fog-avoidance. Ask FlightGPT to find the best-value IndiGo non-stop on your date, steer you to a fog-safe midday slot in winter, and set a fare alert for festival travel when this route sells out fast. We will always show the honest cheapest option, not just the first result.

Frequently asked questions

Is there a direct flight from Kolkata to Patna?

Yes. There are around three non-stops a day, overwhelmingly operated by IndiGo, taking roughly 1h 15m to 1h 20m. It is a frequent, short and well-served corridor.

How long is the flight?

About 1h 15m to 1h 20m non-stop for the roughly 460 km hop — barely an hour airborne.

Which airline should I fly?

IndiGo carries the large majority of traffic on this route and offers the most non-stops. Air India schedules appear occasionally. Go First and Jet Airways no longer operate, and Vistara has merged into Air India.

What is my baggage allowance?

In economy, most airlines allow 15 kg checked plus 7 kg cabin. IndiGo applies its standard limits; Air India often allows more. On such a short hop, cabin-only travel is easy — see our IndiGo and Air India baggage pages.

Can I do web check-in?

Yes. Web check-in opens about 48 hours before departure on most airlines and lets you pick a seat and skip the counter queue. On a short hop with cabin baggage you can head straight to security.

Will winter fog affect my flight to Patna?

Yes, this is the main risk. Patna is prone to dense fog on December and January mornings, which delays or diverts early flights. Prefer a late-morning or midday departure in peak winter and keep onward plans flexible.

What are my rights if my flight is cancelled?

Under DGCA rules you are entitled to a full refund or a free alternative flight if your flight is cancelled. For long delays you may also be due care such as meals, and re-accommodation where applicable.

Am I entitled to a refund if I cancel?

Yes. DGCA rules require airlines to refund statutory taxes and user development fees even on non-refundable fares; the carrier's cancellation charge applies to the base fare. Refundable fares return more.

Can I carry my pet on this route?

IndiGo does not carry pets in cabin. Air India permits pets subject to conditions and advance booking. Confirm directly with the airline well before travel.

Do infants need a ticket?

Infants under two travel on an adult's lap at a nominal fare with no separate seat. Carry the child's birth certificate or ID and book the infant on the same PNR.

How early should I reach the airport?

For a domestic flight, arrive about 2 hours before departure. Patna's terminal is compact but can be congested at peak times, and winter fog can disrupt schedules, so a buffer helps.

Is the flight worth it over the train?

Yes for most travellers. Trains between Kolkata and Patna take 7–10 hours or more, while the flight is barely over an hour. The train suits only those on a tight budget who prefer rail.

When is the best time to visit Patna?

October to March is the most comfortable, with cooler, drier weather. Avoid the peak fog mornings of December and January for flying, and the very hot, humid summer for sightseeing.

Is it cheaper to book direct or via an OTA?

Prices are usually close. Booking direct with IndiGo simplifies changes and refunds; a metasearch like FlightGPT lets you compare every flight and fare on your date in one place first.

Do I need any documents for this domestic flight?

Only a valid government photo ID such as Aadhaar, passport, driving licence or voter ID. No visa is required for domestic travel.
