Airlines flying Kolkata to Patna
IndiGo (6E) is the main operator on the Kolkata → Patna sector, running around three daily non-stops on its A320neo / A321neo fleet, with departures spread across the day from morning to evening. Schedules and any additional carriers can vary by season, so it is worth comparing dates. Because this is a short, well-served domestic hop, fares are usually competitive and the non-stop is the obvious pick — 1-stop options exist but make little sense on a flight barely over an hour. Most travellers simply take the direct service, which takes less time end to end than the airport formalities at each end.
Cheapest time to fly / book
As of May 2026, the cheapest Kolkata to Patna one-way fares open from around ₹3,400–5,800 for off-peak, mid-week departures booked a couple of weeks out, with round trips commonly ₹7,000–12,000. Fares climb around Chhath Puja (Oct–Nov) — Bihar's biggest festival, when demand into Patna spikes sharply — plus Diwali and the December–January holidays. Tuesday and Wednesday departures are usually cheapest, and very early or late flights often undercut midday ones. Book Chhath travel as far ahead as you can, as these are the year's busiest dates. Indicative ranges only — live fares are one query away in the FlightGPT chat.
Flight duration & routing
The non-stop Kolkata → Patna flight blocks about 1h 15m over roughly 460 km, tracking north-west from the Hooghly delta up the Gangetic plain towards the Ganga at Patna. Times are broadly the same in both directions, with winds making little difference over such a short distance. With both cities on Indian Standard Time there is no clock change, so a morning departure from Kolkata lands in Patna well before lunch, leaving the day free for the city's riverside ghats and museums or an onward drive to Bodh Gaya and Nalanda.
Baggage & fares
On domestic economy, IndiGo includes 15 kg checked plus 7 kg cabin on standard fares; higher fare buckets and add-on bundles can raise the allowance — confirm against your ticket. Excess baggage is far cheaper pre-paid online than at the airport counter, where it runs around ₹450–600 per extra kilo. Seat selection and onboard meals are chargeable add-ons on the cheapest fares. Because IndiGo is the dominant carrier here, watch its sales and book early for festival dates; flexible fares cost a little more but help around the unpredictable Chhath rush when both flights and trains into Bihar are heavily booked.
Airports & terminals
Kolkata (CCU) — Netaji Subhas Chandra Bose International uses a single integrated terminal for domestic and international flights, about 15 km north-east of the city; allow time in the busy morning peak. Patna (PAT) — Jay Prakash Narayan International is a compact airport close to the city centre, only around 5 km out, which makes for a quick transfer into town. A modern new terminal has expanded its capacity in recent years. Because of its short single runway and city-centre location, Patna can see weather-related delays in winter fog, so build in a little buffer on early-morning flights.
Do you need any documents?
This is a domestic Indian flight, so there is no visa or passport requirement. You simply need a valid government photo ID that matches the name on your ticket — Aadhaar, passport, driving licence, voter ID or a PAN card are all accepted at security. For children travelling, carry a school ID or birth certificate. Reach the airport about two hours before a domestic departure, and keep your ID handy with your boarding pass at terminal entry and security. DigiYatra is available at major airports if you prefer a faster, face-recognition entry.
Best time to visit
Patna and Bihar are most comfortable from October to March, when cooler, drier weather suits the riverside city, the Bihar Museum and Golghar, and onward trips to Bodh Gaya, Nalanda and Rajgir. Summers (April–June) are very hot, and the monsoon (June–September) brings heavy rain with the Ganga running high. Winter mornings can bring fog that delays early flights. The spectacular Chhath Puja (October–November) is the cultural highlight but also the busiest, priciest travel window. For more, see the destinations guide.
