Patna to Lucknow is a short, thin sector. As of 2026 IndiGo (6E) is the carrier running the non-stop, typically once a day on an Airbus A320-family jet. Frequency on this route is modest and can change with the season, so a single daily departure is the realistic expectation rather than a wide choice of times.
Both cities are well connected to Delhi, so if the non-stop timing does not suit you, a 1-stop routing via Delhi (DEL) on IndiGo, Air India or Air India Express is usually available. For such a short hop, though, the non-stop is almost always the better choice once you factor in the connection wait.
You will not see Go First or Jet Airways here — both have ceased operations — and Vistara has merged into Air India, so Air India is the relevant full-service name on connecting itineraries.
The straight-line distance is roughly 440 km and the non-stop block time is about 1 hour 10 minutes gate-to-gate. With taxi, climb and descent the wheels-up to touchdown portion is shorter still — this is one of the quicker hops in the Hindi belt.
The routing runs broadly westward along the Gangetic plain. There is no time-zone change anywhere in India, so your arrival clock time is simply departure time plus the block time. Allow the usual buffer for security and boarding at Patna, which has a single compact terminal.
This is a regional route with limited capacity, so fares can move sharply when the one daily flight fills up. Booking two to four weeks ahead generally gives the steadiest pricing. Same-week bookings around festivals can be expensive because seats are scarce, not because the route is inherently dear.
| Period | Demand | Fare tendency |
|---|---|---|
| Diwali / Chhath (Oct–Nov) | Very high | Peak — book early |
| Summer holidays (May–Jun) | Moderate–high | Above average |
| Monsoon (Jul–Sep) | Lower | Softer fares |
| Jan–Feb weekdays | Lower | Often cheapest |
Fares quoted by booking sites change constantly, so treat any figure as indicative only and compare on the day you travel.
A few honest levers help on a thin route like this:
Chhath Puja in particular pulls strong Bihar-bound demand, so for late-October and November travel, early booking is the single biggest saving.
With essentially one daily non-stop, you take the slot you are given rather than choosing a window. If your dates are flexible, the connecting-via-Delhi options give you a morning-or-evening choice, but they roughly triple the door-to-door time. For a same-day meeting in Lucknow, the direct flight plus a road buffer to the city is the cleaner plan.
Business: The non-stop is short enough for a day return if timings align; otherwise the Delhi connection eats most of a working day, so an overnight stay is more realistic.
Families: A 70-minute hop is easy with children. Pre-book seats together as the single daily flight can fill up, and carry snacks since catering on a sector this short is minimal.
Students & budget travellers: Honestly, the Patna–Lucknow train and overnight bus are far cheaper and the rail journey is well served. Fly only if time matters more than money on this corridor.
Patna (PAT): Jay Prakash Narayan International Airport has a single passenger terminal, now operating from a larger building. It is close to the city centre, which keeps airport transfers short.
Lucknow (LKO): Chaudhary Charan Singh International Airport handles domestic flights from Terminal 3, the newer integrated terminal. Confirm your terminal on the boarding pass, but most scheduled domestic services use T3.
Patna airport sits within the city, so a taxi or auto from most localities is short — allow extra time during peak traffic near the railway station corridor. In Lucknow, the airport is south of the centre; pre-paid taxis and app cabs are the simplest option, and the metro network serves parts of the city if you are heading to areas near a line. Build in a comfortable buffer at both ends so a short flight does not get undone by road delays.
IndiGo's standard domestic allowance is 7 kg cabin and 15 kg check-in on the lead fare; heavier checked bags need a higher fare bundle or paid add-on. Always confirm against your fare type at booking. See the IndiGo baggage guide for current limits and excess charges. On a regional jet, keep cabin bags within the size template to avoid gate check-in.
Both cities share a north-Indian climate: hot, dry summers (April–June), a humid monsoon (July–September) and cool winters. December and January mornings can bring fog across the Gangetic plain, which occasionally delays the early flight — keep your phone on for schedule updates and avoid tight onward connections in deep winter. Monsoon thunderstorms are the other common cause of holds.
Because this route hangs on a single daily non-stop, set a fare alert as soon as your dates are fixed and book the moment the price looks fair — there is little benefit in waiting, and a sold-out flight pushes you onto a much longer Delhi connection. Use FlightGPT to compare the direct fare against the via-Delhi option side by side so you can see the time-versus-cost trade clearly.
Yes. As of 2026 IndiGo operates a non-stop, typically once daily, on an Airbus A320-family aircraft. Frequency is limited, so book ahead.
The non-stop block time is about 1 hour 10 minutes for the roughly 440 km hop. A 1-stop routing via Delhi takes much longer.
IndiGo runs the non-stop. Air India and Air India Express also connect the cities via Delhi. Go First and Jet Airways no longer operate, and Vistara is now part of Air India.
Yes — Patna and Lucknow are well linked by rail at a fraction of the airfare. Fly only if the time saving matters to you.
If the airline cancels, DGCA rules entitle you to a full refund including taxes, or a free re-accommodation. Refunds apply even on non-refundable fares when the airline cancels.
IndiGo's lead domestic fare allows 7 kg cabin and 15 kg check-in. Heavier bags need a higher fare or a paid add-on. Confirm your fare type before booking.
IndiGo web check-in typically opens 48 hours before departure and closes shortly before the flight. Doing it early helps you pick a seat.
Yes. Dense fog over the Gangetic plain in December and January can delay early-morning departures at both ends. Keep buffers and watch for schedule alerts.
Heavy thunderstorms between July and September can cause holds or short delays, but cancellations are uncommon. Allow a little slack on connections.
Policies vary by airline and most have limited domestic pet provision. Always arrange and confirm carriage with the airline well in advance; it is never guaranteed at the airport.
Infants under two travelling on an adult's lap pay a nominal infant fare and carry no separate baggage allowance. Carry the child's age proof.
Patna has a single terminal. In Lucknow, domestic flights use Terminal 3. Check your boarding pass to be sure.
Prices are often similar, but compare the all-in total after fees. Booking on the airline's own site can make changes and refunds simpler to handle.
No visa — this is a domestic flight. Carry a valid government photo ID; the name must match your ticket exactly.
