On PAT–CCU in 2026, IndiGo is the main and effectively the only reliable non-stop operator, flying A320-family jets two to three times a day. Air India and other carriers appear mostly as one-stop connections, usually via Delhi, which makes little sense on a sub-500 km hop unless the fare is unusually low. SpiceJet has served Patna at times but is not dependable here in 2026. Go First and Jet Airways are defunct — disregard old listings. Because frequency is modest, book early if you need a specific departure time.
Patna and Kolkata are about 470 km apart and the non-stop flight is short — roughly 1 hour 15 minutes. Both cities are on IST, so there is no time change. The actual flying time is brief enough that airport processing dominates the door-to-door journey. There is no need for a connecting flight; one-stop itineraries via Delhi can more than triple your travel time and are worth taking only for a large fare saving.
Demand on this eastern corridor rises around Durga Puja and Chhath (the big Bihar and Bengal festivals in autumn), the year-end holidays and the summer break. Outside those windows fares are usually reasonable. With only a handful of daily non-stops, popular slots fill earlier than on high-frequency routes, so booking two to four weeks ahead is sensible, and earlier for festival travel.
| Period | Demand | Fare pressure |
|---|---|---|
| Feb–Mar | Low | Cheapest window |
| May–Jun (holidays) | Moderate | Good value |
| Oct (Durga Puja / Chhath) | Very high | Peak |
| Nov–Dec (wedding season) | High | Elevated |
| Late Dec | High | Elevated |
Search a couple of days either side of your date — with few daily flights, prices vary noticeably by departure. Midweek tends to beat weekends. Travel hand-baggage-only on IndiGo to access the lowest fare, and add checked bags online if needed. Book ahead of festival peaks rather than hoping for a last-minute drop, which rarely comes on a thin route. Fares are quoted qualitatively here — confirm the live number before booking.
Patna's non-stops typically depart from mid-morning onwards. A late-morning or early-afternoon departure gives you a comfortable same-day Kolkata arrival with time to spare, and clears Patna's winter fog window. Evening departures suit a full day in Patna first but arrive into Kolkata after dark; either works given the short hop. Aim to land before Kolkata's evening road rush if you have onward city travel.
Business travellers: the flight makes a same-day Patna–Kolkata return feasible where the overnight train cannot; pick the earliest non-stop and travel cabin-only to clear the airport fast. Families: the short flight is far easier than the long train with children — book early for festival peaks and reserve seats together. Students: the cheapest IndiGo hand-baggage fare is the value pick, though the overnight train remains a budget option on this corridor. No carrier guarantees a student discount.
Patna's Jay Prakash Narayan International Airport (PAT) moved into a large new single terminal in 2025, with more check-in counters, aerobridges and DigiYatra gates — a big upgrade on the cramped old building. Kolkata's Netaji Subhas Chandra Bose International Airport (CCU) operates from a single integrated terminal handling both domestic and international flights, so there is no terminal confusion at either end of this route. Confirm gates on your boarding pass and the airport screens.
Patna's airport is unusually central — only about 5 km from the city, so cabs take 15–25 minutes outside peak hours, though the single approach road can clog. Kolkata's airport is about 15 km north-east of the centre; app cabs and pre-paid taxis take 30–60 minutes depending on traffic, and the airport is connected to the city's road network and (increasingly) Metro. Use DigiYatra at Patna to speed through security on this short trip.
IndiGo domestic economy allows 15 kg checked and 7 kg cabin in standard fares, with a cheaper hand-baggage-only fare available. On a one-hour hop, cabin-only travel is genuinely practical and lets you skip the belt entirely. Buy any extra allowance online in advance — it is cheaper than the airport counter. For current limits see IndiGo baggage.
The flight is about 1 hour 15 minutes in the air versus eight to twelve hours by train on the Patna–Howrah/Kolkata routes. When airport time is added the door-to-door gap narrows, but the flight still wins decisively for same-day business trips or when time matters. The train remains the cheaper, sleeper-friendly choice for unhurried or overnight travel. For festival travel, book either mode well ahead.
Use DigiYatra at Patna's new terminal — on a one-hour flight, the time you save at security is a meaningful share of the trip. And because the route has only a few non-stops a day, lock in your preferred departure early, especially around Durga Puja and Chhath when seats vanish fast.
Yes. IndiGo operates the non-stop on PAT–CCU, typically two to three times a day, taking about 1 hour 15 minutes. Other carriers mostly offer one-stop connections via Delhi.
The non-stop sector is about 1 hour 15 minutes for roughly 470 km. There is no time difference, as both cities are on IST.
IndiGo is the main non-stop operator. Air India and others appear mainly as one-stop connections. Go First and Jet Airways are defunct, so ignore old listings naming them.
Patna's airport moved into a new single terminal in 2025. Kolkata operates from one integrated terminal for both domestic and international flights, so there is no terminal confusion at either end.
The flight is far faster — about 1h 15m in the air versus eight to twelve hours by train. Fly for same-day trips and when time matters; take the train for lower cost or an overnight sleeper journey.
February–March is usually cheapest. With few daily flights, book two to four weeks ahead, midweek where possible, and earlier for festival travel around Durga Puja and Chhath.
Yes, subject to fare rules. DGCA norms require refund of statutory taxes and applicable amounts; refundable fares return more than non-refundable ones. Cancellation within 24 hours of booking (for tickets bought at least seven days ahead) is free.
IndiGo domestic economy allows 15 kg checked and 7 kg cabin, with a cheaper hand-baggage-only fare available. On a one-hour hop, cabin-only travel is practical. See /airlines/indigo/baggage.
Web check-in opens 48 hours before departure on IndiGo and closes shortly before the gate. Use it to pick a seat and skip the counter if you carry only cabin baggage.
Patna can get winter fog on December and January mornings that delays early departures. A late-morning or midday flight is usually a safer bet in peak fog season.
IndiGo does not carry pets in the cabin. If you need to fly a pet, you would need a carrier and itinerary that allows it (such as Air India, often via a connection) and the required health documents. Confirm the current policy before booking.
Infants under two travel on a lap at a nominal fare without a separate seat or free baggage allowance on most fares. Carry age proof and request bassinet or bulkhead seating in advance.
Base fares are usually the same; direct booking simplifies changes and refunds, while OTAs sometimes run promos. FlightGPT compares both so you see the cheapest reliable option.
Only a valid government photo ID such as Aadhaar, passport, driving licence or voter ID. This is a domestic flight, so no visa is required; DigiYatra is optional but speeds up security.

What you pay on the Patna–Kolkata route hinges on timing: book roughly 3–8 weeks ahead, stay flexible on the day of week, and you usually land the better fare. Search Patna to Kolkata live to see how today's price compares to dates a month out — the gap is often 25–40 percent across IndiGo (non-stop); Air India one-stop.
Last-minute Patna to Kolkata fares move fast, but they're rarely the same across every airline. Run your date through the search above and FlightGPT compares real-time Patna Kolkata prices across IndiGo (non-stop); Air India one-stop — so you grab the cheapest seat still open, not the first one you see.
Most travellers prefer the Patna to Kolkata non-stop option. The direct Patna-Kolkata flight time is ≈ 1h 15m. If you are flexible, 1-stop alternatives through major hubs can be 15-30 percent cheaper. FlightGPT lets you filter by "Direct only" or compare both side by side — useful when you want the cheapest Patna Kolkata ticket but are open to a layover.
Expect Patna–Kolkata fares to vary by cabin, baggage and how the fare is bundled. A bare low-cost fare can end up dearer than a full-service IndiGo (non-stop); Air India one-stop ticket once you add a bag and a seat. FlightGPT shows the all-in price for each option, so you're comparing like for like rather than misleading lead-in fares.
