Diwali 2026 Flights: When to Book, and How to Beat the 3× Fare Surge

If you're flying home for Diwali this year, the bad news arrived early. As of the last week of September, one-way fares on the busiest homecoming routes are already two to three times what they'd cost in a normal week. Bengaluru–Kolkata is showing around ₹16,000 for direct flights on the Durga Puja weekend. Mumbai–Kolkata is at ₹15,000. Delhi–Patna for Chhath is above ₹12,000.

Those are not last-minute prices. Those are the prices six weeks out. Here's what's going on, when to book, and how to make sure the fare you pay is the lowest one that actually exists.

Why fares are already this high

Two things are stacking. First, the festive calendar is compressed this year: Durga Puja starts around 17 October, Diwali falls on 8 November, and Chhath follows within the week. Anyone travelling east or to the Hindi belt is competing for the same seats in the same three-week window.

Second, airlines price by fare bucket, not by date. Each flight has a handful of cheap seats, then a step up, then another. On a normal week the cheap bucket lasts until a few days before departure. On a Diwali route the cheap bucket is gone by mid-September, because the people who plan early bought it. What you're seeing now is bucket three or four. It doesn't come back down.

The dates that matter for Diwali 2026

Durga Puja: roughly 17 to 21 October. Peak demand into Kolkata, Guwahati, Bhubaneswar.

Diwali: 8 November (Sunday). Peak outbound from metros on Thursday 5 and Friday 6 November; peak return Sunday 9 to Tuesday 11 November.

Chhath: 13 to 14 November. Peak into Patna, Ranchi, Varanasi, Darbhanga.

If your dates are fixed to those peaks, book this week. If you have any flexibility, the next section is where the money is.

Four ways to pay less

Move one day. Flying out on Wednesday 4 November instead of Friday 6, or returning Wednesday 12 instead of Sunday 9, routinely halves the fare on the same route. The festival is the same; the seat is half price.

Check the secondary airport. Bengaluru–Kolkata is brutal; Bengaluru–Bhubaneswar plus a train can be a third of the price. Delhi–Patna is brutal; Delhi–Gaya or Delhi–Darbhanga may not be.

Compare the final price, not the search page. The same seat is priced differently on the airline's own site, MakeMyTrip, Ixigo, Cleartrip and Goibibo, because each adds its own convenience fee, runs its own coupons and caches fares at different moments. On a normal fare the gap is a few hundred rupees. On a ₹15,000 Diwali fare the gap between the cheapest and dearest way to buy the same seat can be over a thousand. We wrote up exactly how that happens in why the same flight costs different on every website. The short version: go to the payment screen on each before you decide.

Book once you've compared, not before. Diwali fares only move one way. Waiting for a sale that never comes is how people end up paying ₹18,000 for a seat that was ₹14,000 the week they first looked.

If you're travelling as a group

Family trips for Diwali are usually four to six people, and that's where the fare bucket problem bites hardest: there may be two seats in the cheap bucket and the other four step up. Search for the whole group in one go rather than person by person, and if the price jumps, try splitting across two flights on the same day. It's a nuisance and it's often ₹2,000 a head cheaper.

Doing this in one search instead of six tabs

This is the specific problem Bookkr was built for. Type the trip in plain English, "Bengaluru to Kolkata, 16 to 22 October, family of four", and it returns the flights you can actually book with each provider's price side by side for the same departure, including the airline's own site. You see which one is cheapest today and choose where to book. If you're planning with family, add them to the trip and everyone's constraints go into the same search.

It doesn't make Diwali fares cheap. Nothing does. It makes sure you pay the lowest price that exists for the seat you want, which this year is worth a few thousand rupees a person.

The short version

Fares on the homecoming routes are already 2–3× and rising. Book this week if your dates are fixed. Move a day or an airport if they're not. Compare the payment-page price across the airline and at least two OTAs for the exact flight, or use a tool that does it in one search. Don't wait for a sale.
