Cheapest Time to Fly to Delhi (and the Most Expensive)
The cheapest time to fly to Delhi is usually late January–March and select fall weeks—while December holidays, summer peak travel, and major festival periods are often the priciest.
Flights to Delhi can swing a lot—mostly because long-haul demand stacks up around winter holidays, summer travel, and big festival weeks. If you can shift your trip by even a few days, you can often avoid the ugliest price spikes.
Quick Take
- Cheapest time to fly to Delhi: late January–March, May (some weeks), September, and late October–November
- Most expensive time to fly to Delhi: late December–early January, June–July, and festival-heavy weeks (often October–November)
Cheapest Time to Fly to Delhi
The best deal windows usually happen when you’re outside holiday travel surges—and when airlines have more empty seats to fill on long-haul routes.
Late January to March (Post-holiday deal season)
After the New Year travel wave fades, pricing often settles. This is one of the most reliable stretches to find better fares into Indira Gandhi International Airport (DEL).
Money-saving tip: Midweek departures: Tuesday–Thursday flights often price better than weekend-heavy dates.
Heads-up: Spring break overlap: some US spring break weeks can bump prices, especially on popular departure days.
May (Pre-summer, deal-friendly weeks)
Not every May week is cheap, but some can be—especially if you’re avoiding holiday weekends and not traveling right as summer demand spikes.
Money-saving tip: Avoid long weekends: price-check the weeks after any major US travel weekends.
Heads-up: Heat factor: May in Delhi can be very hot—great for airfare odds, less great if you hate intense heat.
September (After summer demand cools)
Once summer travel patterns fade, September often has better pricing odds again. It’s also a month where being flexible by a couple days can really pay off.
Money-saving tip: Date-shift test: compare leaving 1–2 days earlier or later—Delhi pricing can change fast.
Heads-up: Weather: late monsoon season can still be in play, depending on the year.
Late October to November (Fall shoulder window)
This is one of the stronger “value” windows for airfare in many years—especially after summer and before late-December holiday spikes.
Money-saving tip: Target mid-November: it often prices better than late December and early January.
Heads-up: Festival pricing: some October–November weeks can spike if they line up with major festival travel.
Most Expensive Time to Fly to Delhi
Delhi gets priciest when US holiday travel overlaps with India travel demand—plus peak long-haul seat inventory gets eaten up quickly.
Late December to Early January (Holiday rush)
This is typically the highest price period. Flights often surge for late-December departures and early-January returns.
Peak within peak: The week before Christmas through the first week of January.
June to July (Summer peak travel)
Summer travel demand can keep the price floor high—especially for family travel dates and weekend-heavy itineraries.
Peak within peak: Late June into mid-July often has fewer deals.
October to November (Festival-heavy weeks)
Major festival periods can raise prices—especially when many people are traveling domestically and internationally around the same time.
Peak within peak: Weekend departures during festival weeks tend to price worst.
Want Better Weather Without Peak Flight Prices?
If you want comfortable trip timing without paying top-dollar airfare, these windows are usually your best bets:
- February to March: often the best blend of pricing odds and comfortable timing
- September: post-summer price softening with better deal chances
- Late October (non-festival weeks) to mid-November: solid airfare odds before year-end surges
Best Booking Window for Cheap Flights to Delhi
Delhi is a long-haul route where tracking earlier usually wins—especially if you want decent routings and fewer painful layovers.
- Low/shoulder seasons: start tracking 3–6 months ahead
- Peak seasons (late December, summer, festival weeks): start tracking 6–9+ months ahead
Extra tip: Compare nearby departures: a different US departure airport can sometimes change the price more than you’d expect on India routes.
