Route Overview: Delhi (DEL) to Patna (PAT)
Indira Gandhi International Airport (DEL) in New Delhi connects directly to Jay Prakash Narayan International Airport (PAT) in Patna, Bihar. The straight-line distance is roughly 1,000 kilometres, making it a short-haul route that rarely takes more than 90 minutes in the air. This convenience drives high demand year-round, particularly among the large Bihari diaspora in Delhi NCR.
Patna Airport (IATA: PAT) handled over 3.6 million passengers in FY2023–24 according to the Airports Authority of India (AAI, 2024), making it one of the busiest Tier 2 airports in the country. It has a single terminal with a recently upgraded departure hall, two aerobridges, and a handful of food stalls post-security.
Which Airlines Fly Delhi to Patna?
Three major carriers operate non-stop service on this route. IndiGo dominates with the highest frequency, but Air India and SpiceJet provide meaningful alternatives, especially when IndiGo seats are sold out or overpriced. Akasa Air has been evaluating Patna as an expansion market but had not launched regular service as of early 2026.
| Airline | Daily Flights (Approx.) | Baggage Included | Typical Fare Range (One-Way) |
|---|---|---|---|
| IndiGo | 4–6 | Cabin only (paid add-on for check-in) | ₹2,800 – ₹11,000 |
| Air India | 2–3 | 15 kg checked included | ₹3,500 – ₹13,000 |
| SpiceJet | 2–3 | Cabin only (paid add-on for check-in) | ₹2,900 – ₹10,500 |

When Are Delhi to Patna Fares Cheapest? Month-by-Month Breakdown
Fare patterns on DEL–PAT are more dramatic than almost any other Indian domestic route, driven almost entirely by Bihar’s major festivals. Knowing this calendar is your single biggest advantage when planning travel. According to fare trend data tracked on HappyFares, the difference between the cheapest and most expensive months can exceed 300%.
| Month | Demand Level | Fare Range (One-Way) | Notes |
|---|---|---|---|
| January | Moderate | ₹3,500 – ₹6,500 | Post-winter rush settling |
| February | Low | ₹2,800 – ₹5,000 | Best value month |
| March | Low–Moderate | ₹2,900 – ₹5,500 | Holi causes a brief spike |
| April | Moderate | ₹3,200 – ₹6,000 | Board exams drive some return travel |
| May | Moderate | ₹3,500 – ₹7,000 | Summer vacations begin |
| June–July | Low | ₹2,800 – ₹5,000 | Monsoon — travel dips sharply |
| August | Low–Moderate | ₹3,000 – ₹5,500 | Raksha Bandhan spike in late Aug |
| September | Moderate | ₹3,500 – ₹6,500 | Navratri creeps up |
| October | Very High | ₹7,000 – ₹15,000 | Diwali + early Chhath season |
| November | Peak | ₹8,000 – ₹18,000 | Chhath Puja — highest fares of the year |
| December | High | ₹5,000 – ₹10,000 | Year-end travel, winter holidays |
Why Chhath Puja Makes This Route So Expensive
Chhath Puja is Bihar’s most important festival, observed with great devotion across the diaspora. An estimated 3 million+ Bihari migrants reside in Delhi NCR alone, and a significant share attempts to travel home around Chhath — compressing enormous demand into a 10-day window. Seats disappear entirely, and airlines fill every available capacity. If you’re travelling for Chhath 2026, book by August at the latest.

How to Book the Cheapest Delhi to Patna Tickets
Timing and flexibility are the two levers that determine how much you pay. A passenger who books 45 days ahead on a Tuesday morning will almost always pay less than someone booking 10 days out on a Sunday evening — often by ₹2,000–₹3,500 on this route. Here are the strategies that consistently work.
Book 30–45 Days Ahead for Normal Travel
For travel outside the festival windows (January–September, excluding March Holi week), booking 30–45 days in advance almost always gets you fares in the ₹2,800–₹5,500 range. Airlines release inventory in fare buckets, and the lowest buckets fill first. Waiting longer moves you into progressively higher buckets.
Book 60–90 Days Ahead for Festival Season
For Diwali (October) and Chhath Puja (November), treat flight booking the same way you’d treat train tatkal — start early. The moment airline schedules open for those months (typically 3 months prior), search on HappyFares and lock in the cheapest available seat. Prices only go up as the festival approaches.
Travel Light to Save More
Both IndiGo and SpiceJet on this route offer their cheapest fares without any checked baggage. If you can manage with a 7 kg cabin bag for a short trip home, you’ll save ₹500–₹1,200 compared to bundled fares. Air India includes checked baggage but starts at a slightly higher base fare — worth comparing for trips where you’re carrying significant luggage.

Patna Airport (PAT) — What to Expect
Jay Prakash Narayan International Airport in Patna serves both domestic and international routes (primarily Gulf destinations). For arriving passengers, the terminal is compact and you’ll typically collect baggage within 15–20 minutes of landing. Pre-paid taxi counters are available at the exit — agree on a fare before boarding private cabs outside. The airport sits roughly 7–8 km from the Patna city centre.
Getting to and from Patna Airport
- Pre-paid taxi: ₹250–₹400 to city centre; available 24/7 at the airport exit
- App-based cabs (Ola/Uber): Often available, though surge pricing applies during festival arrivals
- Auto-rickshaw: Cheaper option for short distances; negotiate the fare upfront
- City bus: BSRTC runs limited services — not ideal for travellers with luggage
There are no metro rail connections to Patna Airport as of early 2026, though this is under consideration in the city’s long-term urban transit plan.
Delhi to Patna by Train vs Flight — Which Is Better?
The Rajdhani Express covers Delhi to Patna in approximately 12–14 hours and costs ₹1,000–₹2,500 in sleeper or AC classes — significantly cheaper than flying. However, during Chhath Puja and Diwali, train tickets sell out months in advance and waiting list clearance is uncertain. When train seats aren’t available, flying becomes the only reliable option. For anyone who values time on a routine trip, flying saves nearly a full day of travel.
| Mode | Travel Time | Typical Cost | Best For |
|---|---|---|---|
| Flight | ~1h 25m | ₹2,800 – ₹18,000 | Speed, convenience, festival season backup |
| Rajdhani Express | 12–14 hours | ₹1,000 – ₹2,500 | Budget travel when booked well in advance |
| Road (self-drive) | 14–16 hours | ₹3,000–₹5,000 (fuel + tolls) | Groups with lots of luggage, flexible schedules |
