Airlines and non-stop options
Patna to Delhi is one of eastern India's busiest trunk routes. IndiGo dominates the schedule, with Air India, Air India Express and SpiceJet all adding non-stops. Departures run from early morning to late night, so there's usually a convenient slot.
The high carrier count keeps fares competitive on this corridor. Ignore old listings showing Go First or Jet Airways (both defunct) or Vistara (merged into Air India).
Flight time, distance and routing
The distance is about 945 km and scheduled block time is roughly 1 hour 45 minutes. There's no time-zone change — both run on IST.
All services fly non-stop on a north-westerly track up the Gangetic plain. Note that Patna's runway has historically had operating constraints, so flights can be weight- or timing-sensitive; this rarely affects passengers directly but can influence schedules.
Best time to book and seasonal fares
This is a heavy migrant and VFR route, so demand spikes around Chhath Puja, Holi and Diwali when Bihar-bound and outbound travel surges in both directions. Outside festivals, booking two to three weeks ahead gets a fair fare.
| Period | Demand | Booking advice |
|---|
| Apr–Jun (summer) | Moderate | Book 2–3 weeks ahead |
| Jul–Sep (monsoon) | Lower | Best value outside festivals |
| Oct–Nov (Chhath/Diwali) | Very high | Book 4–6 weeks ahead |
| Dec–Jan (winter/fog) | High | Book early; expect fog delays |
Getting your fare cheaper
Honest ways to save:
- Avoid Chhath Puja week if at all possible — it's the biggest fare spike of the year on this route.
- Mid-week departures are usually cheaper than Friday and Sunday.
- Compare all four carriers; SpiceJet and Air India Express often undercut on this corridor.
- Travel hand-baggage-only on a lighter fare where one exists.

Best departure windows
Morning and early-afternoon departures are the most reliable. The big caveat is winter fog (mid-Dec to late Jan): Delhi's dense morning fog routinely delays the earliest flights, and Patna gets fog too. In those weeks, a late-morning or midday departure (once fog has lifted) is far less likely to be disrupted than the dawn slot.
Advice by traveller type
Business: A morning departure gives a workable same-day return. Outside fog season, this is a dependable corridor. Families: Mid-morning flights avoid both the dawn rush and late-night fatigue; the 1h 45m duration is manageable for children. Students and budget flyers: Book early, compare SpiceJet and Air India Express, and travel light — the alternative is a 15-hour-plus train, so the flight saves a full day.
Airports and terminals
Patna (PAT): Jay Prakash Narayan International has a single terminal (a newer, larger terminal building has expanded capacity). It's centrally located but compact, so arrive in good time at peak hours. Delhi (DEL): IndiGo, SpiceJet and Air India Express use Terminal 1; Air India uses Terminal 3. Check your terminal before booking onward connections, as T1 and T3 are well apart.
Getting to and from the airport
Patna: The airport sits close to the city centre, roughly 5–7 km; autos and app cabs reach most areas in 20–30 minutes. Delhi: From Terminal 3 use the Airport Express Metro into central Delhi; from Terminal 1, app cabs or the metro (via nearby stations) work well. Allow 45–75 minutes in traffic, and use the free inter-terminal shuttle if connecting between T1 and T3.
Baggage allowance
Domestic economy is typically 15 kg checked plus a 7 kg cabin bag on IndiGo, Air India and SpiceJet; Air India Express fare families vary, with some lighter no-checked-bag fares. On a busy festival route, checked bags are common, so confirm your allowance early. See the IndiGo baggage guide for current limits.
Travel tips and weather
The biggest planning factor is winter fog: from mid-December to late January, both Patna and Delhi can see dense morning fog that delays or reschedules flights. Build in buffer time and avoid tight onward connections in those weeks. Summer (Apr–Jun) is very hot on the Gangetic plain; the monsoon (Jul–Sep) brings humidity and occasional rain delays.
FlightGPT tip
This corridor swings between four airlines and spikes hard around Chhath and Diwali, while winter fog adds delay risk. FlightGPT shows every airline's live fare in one view, so you can grab the cheapest seat, book around the festival surge, and pick a later slot that dodges the worst of the fog.
