Diwali 2026 is around October 20. If you haven't booked family flights by late July, expect to pay significantly more — fares on popular routes like Bengaluru–Delhi or Mumbai–Goa can spike 60–90% compared to normal midweek fares by mid-September. Christmas and New Year is worse: book by late August for December travel, or you'll be choosing between expensive and very expensive.
TL;DR — the booking windows in plain numbers
Book Diwali 2026 domestic flights by late July or early August — that's roughly 10–14 weeks before departure. For Christmas and New Year travel (Dec 24 – Jan 2), the sweet spot is late August to early September, or 14–18 weeks out. After these windows close, fares on high-demand routes rise sharply and availability for families needing adjacent seats becomes genuinely limited. Set price alerts now if you haven't booked — but set them with realistic targets, not aspirational 2019 prices.
Diwali 2026 — when is it and what does it do to flight prices?
Diwali in 2026 falls around October 20 (confirm the exact date via official sources as lunar calendar calculations can shift). The peak travel window is typically the 5–7 days before the main date through the 3–4 days after — so approximately October 14–26. Flights out of metros (Bengaluru, Mumbai, Hyderabad, Chennai, Pune) to hometown destinations (Lucknow, Patna, Nagpur, Bhubaneswar, Raipur, Ranchi, Amritsar) surge hardest during this window, and the surge is very real.
Based on patterns from previous years, domestic fares on high-demand Diwali routes during the 5-day peak can run 1.5x–2.5x the normal fare for that route and time. A Bengaluru–Lucknow flight that costs around ₹4,000–₹5,500 in a normal October midweek can reach ₹9,000–₹13,000 or more in the 3 days around Diwali eve. These are indicative ranges — always search live fares on FlightGPT or MakeMyTrip/Cleartrip to see what's actually available.
The implication for families: if you're booking for 4+ people, the fare difference between booking in late July versus mid-September is often ₹15,000–₹30,000 total — which is not small. The earlier booking window (10–14 weeks) exists specifically because that's when airlines release Diwali inventory at base prices, before the surge algorithms kick in as the date approaches and seats fill up.
Christmas and New Year flights — why 14+ weeks matters
The December 24 – January 2 window is the single most expensive domestic travel period of the year for Indian families, competing only with Diwali. The reasons stack: schools are on break (so families are travelling), year-end corporate travel is winding down, and outbound international tourism from India also peaks (pushing up seat competition on trunk routes to hub airports). Goa, Andaman, Manali, Shimla and Rajasthan heritage towns all see massive spikes.
The data-informed recommendation is to book Christmas and New Year flights by late August — around 14–18 weeks before departure. Here's why the window is longer than Diwali: Christmas and New Year have a longer peak window (9 days versus Diwali's 5-7), and international routes feeding Indian airports also peak simultaneously. December 23–26 and December 30 – January 1 are the hardest seats to get at normal prices.
If you're booking an international family trip for Christmas 2026 — say, Singapore or Dubai — push the booking even earlier. Air India's international routes out of Delhi and Mumbai for December 22–27 sell out months in advance for the economy cabin. Use FlightGPT's flexible-date search to shift a day or two — flying on December 23 vs December 24 can save ₹5,000–₹12,000 per person depending on route.
Cheapest days and times to fly during peak season
Even during peak season, not all dates and times are equally expensive. Some patterns that hold fairly consistently on Indian domestic routes:
- Diwali week: October 17–19 (2–3 days before Diwali) is the most expensive. Flying on Diwali day itself (October 20) or the day after (Oct 21) can sometimes be 15–25% cheaper — people want to be home before the main night, not travelling during it. The weekend after Diwali (Oct 24–25) is moderate and worth considering for the return.
- Christmas: December 25 itself is often slightly cheaper than December 23–24, because most travellers want to reach their destination before Christmas. Flying out on Christmas Day afternoon or December 26 morning is worth checking. January 1 is expensive outbound (returning from Goa/hills) but January 2 drops sharply.
- Early morning and late night flights: 5–7 AM and 10 PM+ departures tend to be 8–15% cheaper than mid-morning or late afternoon departures during peak periods, even on the same day. With kids it's harder, but if your family can manage an early-morning airport run, the saving is real.
- Midweek travel: Tuesday and Wednesday outbound flights are cheaper than Friday–Sunday across almost all seasons. During Diwali and Christmas this differential narrows, but it's still there.
How to use price alerts on Indian OTAs effectively
Price alerts on MakeMyTrip, Cleartrip, and EaseMyTrip are useful, but they need to be set with realistic expectations. Here's what actually works:
- Set the alert early — June/July for Diwali, July/August for Christmas. The alert captures the initial price and notifies you of drops or unusual rises. If you set it in September for a Diwali flight, you're already past the ideal window and the alert will mostly show you rising prices, which is demoralising and not actionable.
- Set a realistic target price — not the lowest fare you've ever seen on that route, but roughly the current midweek off-peak fare plus 20–30% for peak-period premium. Chasing ₹2,500 Bengaluru–Delhi fares during Diwali week is not a strategy, it's wishful thinking.
- Use FlightGPT for flexible-date searches — comparing ±3 days around your target date often surfaces fares that are 20–40% cheaper on adjacent dates, especially around the shoulder of a peak window (flying Oct 16 vs Oct 19, or Dec 22 vs Dec 24).
- Book the outbound first — if seats on the outbound are filling up, book that leg even if you haven't sorted the return yet. Return seats on less-demanded routes tend to be more available, and you can use a different carrier on the way back if needed.
A note on credit card EMI offers: IndiGo, Air India and OTAs like MakeMyTrip periodically run EMI offers on HDFC, ICICI, and Axis cards that can bring the effective cost down — often 5–10% off or zero-cost EMI. These tend to appear around festival dates precisely because airlines know families are price-sensitive. Keep an eye on OTA promotional banners in the August–September window before Diwali.

What to do if you've already left it late
If you're reading this in late September and Diwali flights look expensive, you have a few options:
- Shift by one or two days: Flying October 16 instead of October 17, or returning October 23 instead of October 22, can still yield meaningfully cheaper fares than the peak days.
- Check less obvious carriers: SpiceJet sometimes has capacity where IndiGo and Air India are sold out — their load factors tend to be lower. Akasa Air is worth checking on routes they operate (Delhi–Mumbai, Bengaluru–Mumbai, Delhi–Bengaluru). Don't ignore Air India Express on routes where they overlap.
- Consider a connecting flight: A Bengaluru–Lucknow nonstop may be ₹12,000 during peak week, but Bengaluru–Delhi–Lucknow on a connecting itinerary (separate tickets) may cost ₹7,000–₹8,500. It's longer and riskier (separate ticket = you absorb the misconnect cost), but the math sometimes works for families watching the budget.
- Ask yourself if a train works: On a 600–900 km route with Rajdhani or Vande Bharat availability, a train is often dramatically cheaper than a peak-season flight, faster than the airport-to-airport total journey time, and easier with young kids. This is not a cop-out — it's a real option Indian families use.
Frequently asked questions
When exactly is Diwali 2026?
Diwali in 2026 falls around October 20. Confirm the exact date via official calendar sources as the lunar calculation can shift by a day. The peak travel window for domestic flights is approximately October 14–26, with October 17–20 being the most expensive days to fly.
How far in advance should I book family flights for Diwali 2026?
Book 10–14 weeks in advance — so by late July to early August 2026 for Diwali week travel. After mid-September, fares on popular routes like Bengaluru–Patna, Mumbai–Lucknow or Hyderabad–Ranchi typically rise sharply and adjacent family seating becomes harder to secure without paying extra.
Is Christmas or Diwali more expensive for domestic flights in India?
Both are very expensive, but Christmas–New Year (Dec 24 – Jan 2) is generally the pricier window on Goa, Andaman, Rajasthan and hill-station routes. Diwali is more expensive on hometown routes — North and East India destinations like Patna, Lucknow, Ranchi and Bhubaneswar. The worst-case premium over normal fares is roughly comparable at peak — typically 1.5x–2.5x the off-season fare.
Which day of the week is cheapest to fly during Diwali or Christmas?
Tuesday and Wednesday are generally cheapest even during peak season, though the differential narrows. Flying on Diwali day itself (rather than the 2–3 days before) or on Christmas Day rather than Christmas Eve can also yield savings of 10–20% on some routes. Early morning (5–7 AM) and late night (10 PM+) departures tend to be 8–15% cheaper than mid-morning flights on the same day.
Do price alerts on MakeMyTrip actually work for peak season booking?
They work if set early enough (June for Diwali, July for Christmas) and at realistic price targets — not aspirational lows. Alerts set in September for an October Diwali flight mostly track rising prices, which is not useful. Set the alert when the price is still reasonable and let it notify you of any dip below your target. FlightGPT's flexible-date search is useful for comparing adjacent dates to find shoulder-period prices.
Can I get cheaper Diwali or Christmas flights on a connecting itinerary?
Sometimes, yes — booking two separate tickets (say, Bengaluru–Delhi on IndiGo and Delhi–Patna on Air India Express) can be cheaper than a direct nonstop during peak week. The risk is that if the first flight is delayed and you miss the connection, you bear the rebooking cost since they're separate tickets. It works best when the connection time is generous (3+ hours at a large airport like Delhi) and when the saving justifies the risk.
