Delhi–Kolkata Durga Puja fares regularly hit 3–4x their usual price. Last-minute during October is one of the most expensive domestic ticket purchases you can make. Here's what the surge looks like, why it happens, and what your options are.
TL;DR — What You're Actually Dealing With
Durga Puja falls in October (Panchami to Dashami, typically a 5-day period), and the Delhi–Kolkata (DEL–CCU) route is among the worst places to be booking last-minute during this window. Fares on this route can hit ₹18,000–₹35,000 one-way all-in for economy during the peak 3–4 days of Puja, compared to a typical ₹4,000–₹8,000 outside festive season. If you can book even 3–4 weeks ahead, you'll pay roughly half to a third of what you'd pay in the final 72 hours. If you must fly last-minute during Puja week, read on — there are some genuine tactics that can blunt the damage.
Why Durga Puja Is the Worst Time to Book Delhi–Kolkata Last-Minute
Kolkata's relationship with Durga Puja is unlike any other city's with any other festival in India. This isn't just a holiday — it's the cultural centrepiece of Bengali life. Every Bengali family wants to be in Kolkata for Puja, and a significant chunk of Kolkata's Bengali diaspora lives in Delhi-NCR. The scale of the reverse migration to Kolkata during Puja week is massive. Every seat on every DEL–CCU flight gets bought up weeks in advance.
Add to this the Kolkata business traveller who needs to return for family, the NRI flown in from abroad who books months out (meaning they're not competing with you for the last-minute seat — they're already gone), and the government/BSNL-type employees who book on official quota. By the time you're searching 72 hours before Puja's first day, you're competing for the leftover scraps.
It's not just IndiGo. Every carrier flying DEL–CCU — Air India, Akasa, SpiceJet — prices at near-maximum yield during this window. There is no cheap option. There's just less-expensive and more-expensive among the options that haven't sold out.
The Price Surge in Real Terms
I've tracked this route through Puja season over several years. The pattern is remarkably consistent even as absolute fare levels shift year to year. Here's what the surge looks like:
| Booking Timing | Typical DEL–CCU Fare Band (all-in, economy) |
|---|---|
| 3+ months before Puja | ₹4,000–₹7,000 |
| 4–6 weeks before Puja | ₹6,000–₹12,000 |
| 2–3 weeks before Puja | ₹10,000–₹18,000 |
| Within 1 week of Puja | ₹15,000–₹28,000 |
| Within 72 hours of departure | ₹18,000–₹35,000+ |
These are rough ranges for 2025–2026; verify current fares on FlightGPT or the airline's own site at the time of booking. The exact peak dates shift slightly each year depending on when Panchami falls, so check the specific Puja calendar for 2026.
What makes this especially painful: October 2026 Durga Puja dates will be announced well in advance (it's a known quantity). There's no excuse not to book early if you know you're going. The last-minute premium here isn't a surprise — it's a tax on procrastination.
What Happens to CCU on the Return Side
The surge isn't just DEL–CCU. The return leg — CCU–DEL in the 3–4 days after Dashami — is equally brutal. In some years, the return fares are even higher than the outbound because the demand wave is concentrated into a narrower window (everyone wants to leave Kolkata on the same two days after Puja ends).
If you're booking last-minute and need both legs, budget for the full surge on both directions. A round-trip during peak Puja week with last-minute booking could easily run ₹45,000–₹70,000 for what would be a ₹12,000–₹16,000 round-trip with 8 weeks' notice. That's not a typo. This is one of the most dramatic seasonal fare spikes in the Indian domestic market.
If You Must Fly Last-Minute: Actual Tactics That Help
You have a genuine emergency — a family situation, an unavoidable work commitment — and you need to get to Kolkata during Puja week with less than 72 hours' notice. Here's what actually helps:
- Check all carriers simultaneously. IndiGo, Air India, Akasa — run them all. During Puja, Air India sometimes has seats available when IndiGo is sold out, or vice versa. FlightGPT's search will surface all of them at once. Don't check one carrier and assume the rest are the same.
- Look at nearby dates one day before or one day after. If Dashami-eve is ₹32,000, the day before Panchami might be ₹18,000. The surge has specific peak days — flying in a day earlier or later can save ₹8,000–₹12,000.
- Check adjacent departure airports. Delhi has IGI (DEL) as the main airport. If you're in Noida or Gurgaon, also check if any carrier has a deal from a nearby point. This rarely helps but worth a glance.
- Connecting flights via a third city. DEL–BOM–CCU or DEL–BLR–CCU sounds absurd, but during peak Puja, direct fares can sometimes exceed the price of two-leg itineraries on different carriers. The risk is missing the connection; stick to the same airline if you go this route.
- Check if the Howrah Rajdhani AC First/2A has last-minute seats. Tatkal for trains opens one day before departure. Rajdhani 2A from Delhi to Howrah is around ₹4,000–₹6,000 Tatkal — expensive for a train but dramatically cheaper than a last-minute Puja flight, and arrives in Howrah about 17 hours after departure. IRCTC app is the only place to book this; have your account set up in advance.
What to Do Starting Right Now if You Know You're Going
If you're reading this in June or July and Puja travel is a possibility, book today. Not tomorrow — today. Even 'I might go' is good enough reason to book a refundable or change-allowed fare on IndiGo or Air India and amend or cancel it later. The refundable fare premium over non-refundable is usually ₹500–₹1,500; that's nothing compared to the ₹12,000–₹20,000 premium you'll pay if you wait until October.
IndiGo's SuperSaver fares are non-refundable but have low change fees (you pay a fare difference if the new fare is higher, but the base change fee is manageable). Air India's flexible fares are worth looking at for this specific route during festive periods.
Set a fare alert on FlightGPT and track the route from now. The price curve on DEL–CCU during Puja is almost always upward — it rarely drops as you get closer. The chart essentially goes one direction.

Is There Any Silver Lining?
Honestly? For purely last-minute last-minute — 12–24 hours before departure — there's an outside chance that an unsold seat shows up at a slightly lower price if the flight is running below full. This is rare on DEL–CCU during Puja but not impossible, especially on less-favoured time slots (very early morning or late night). I'd never plan around it, but if you find yourself searching and see a 6am departure that's ₹4,000 below the 9am option, that's real and worth taking.
The other silver lining: Puja is concentrated. The worst days are usually the 4–5 days around Panchami through Dashami. Flights on the periphery of that window — a week before or a week after — normalise quickly. If your trip has any flexibility at all, even a 2-day shift can save you a meaningful amount.

Frequently asked questions
How expensive is a Delhi to Kolkata flight during Durga Puja if I book last minute?
For bookings within 72 hours during Durga Puja's peak days (Panchami through Dashami in October), expect ₹18,000–₹35,000 all-in for a one-way economy ticket — compared to ₹4,000–₹7,000 with 3 months' notice. The surge is consistent year on year. If you know you're going, book as early as possible.
Which airlines fly Delhi to Kolkata during Durga Puja and who has the most seats?
IndiGo has the highest frequency on DEL–CCU, typically 5–8 flights per day. Air India also operates this route with multiple daily flights. Akasa flies DEL–CCU with growing frequency. SpiceJet operates limited services. During Puja week, all carriers tend to sell out the popular daytime slots weeks in advance — check all of them, not just IndiGo.
When does the Durga Puja fare surge start and when does it end?
The surge typically begins 3–4 weeks before Puja starts, as early buyers lock up advance seats. Peak pricing is usually in the 2 weeks leading up to Panchami and the 3–4 days after Dashami (return leg). Fares normalise roughly 5–7 days after Dashami. The exact Puja dates shift annually per the Bengali calendar — check the specific 2026 Puja calendar for precise peak windows.
Is the train a viable alternative for Delhi–Kolkata during Durga Puja?
Yes, particularly if you book Tatkal (available 1 day before, opens at 10am on IRCTC app). Rajdhani Express 2A Tatkal from Hazrat Nizamuddin to Howrah typically runs ₹4,000–₹6,500 — expensive for a train but dramatically less than ₹25,000+ for a Puja-week flight. Journey time is about 17 hours. The catch: even Tatkal train seats fill quickly during Puja. Set an IRCTC alarm.
Can I get a refund or change a Delhi–Kolkata Puja ticket if my plans change?
Depends on the fare type. IndiGo's SuperSaver fares are non-refundable but allow date changes for a fee plus any fare difference. Air India's flexible fares allow changes with lower penalties. If you're booking months ahead and aren't sure you'll go, pay the small premium for a changeable fare — it's cheap insurance against the rebooking cost of a ₹25,000 ticket you can't use.
What's the cheapest time of day to fly Delhi–Kolkata last minute during Puja?
Very early morning (before 7am) and late night departures (after 9pm) tend to be slightly cheaper than daytime slots even during Puja — typically ₹3,000–₹6,000 less than peak morning departures. They sell out too, just slightly later. Check all available departure times on FlightGPT rather than assuming the first result shown is your only option.
