The cheapest time of day to fly from India is generally the early morning (5:30–7:00 AM) or late night (10:30 PM onwards) — slots that most passengers avoid because of the inconvenience. Airlines price them lower to fill seats they would otherwise sell with difficulty. Here is exactly how much cheaper, why, and how to make these slots work for you.
TL;DR — cheapest departure times from India
On domestic Indian routes, 5:30–7:00 AM departures and 10:30 PM–12:00 AM departures are consistently the cheapest departure windows. On international routes, late-night departures (11 PM–2 AM from Indian airports) tend to be cheaper than the mid-morning or early-afternoon peaks. The difference is typically ₹500–₹2,500 cheaper on domestic and ₹1,500–₹5,000 cheaper on international routes compared to the most popular midday and early-evening slots.
Why early-morning flights are cheaper
Early-morning slots (5:30–7:00 AM) are the first departures of the day, which means a few things that airlines price around:
- Demand is lower. A large portion of leisure travellers and families avoid setting a 3:30–4:00 AM alarm to catch a 5:30 departure. Airlines know this and price the slot down to make it attractive enough to fill.
- Airport efficiency. Airlines like early-morning slots because aircraft that turn around overnight can begin the day's flying cycle without ATC delays that build up through the day. To encourage passengers to take these flights and keep load factors high, they often price them as the cheapest option on the schedule.
- Business travellers avoid them too. The peak business travel window is roughly 7:30–10:00 AM — when business travellers want to arrive in the destination city by mid-morning. The 5:30 departure does not land at a convenient time for a 9 AM meeting in the next city, so fare competition for these seats comes almost entirely from leisure and price-sensitive passengers.
Practically: on a route like Mumbai–Delhi, the 5:50 AM IndiGo or Akasa flight is often ₹800–₹1,800 cheaper than the 9:00 AM or 10:30 AM slot on the same day. I have taken the 6:00 AM from Indore to Delhi more times than I can count — yes, you leave home at 4:15 AM, but arriving in Delhi by 7:45 AM means you have a full working day ahead and spent less getting there.
Why late-night flights are cheaper
The other cheap window is the true late-night departure — 10:30 PM onwards, sometimes running into midnight or 1 AM. These are priced low for different reasons than the early-morning slots:
- Arrival timing inconvenience. A 10:30 PM Delhi flight arriving in Mumbai at midnight means getting to your hotel at 1–1:30 AM. For most travellers, that disrupts the next morning. People pay a premium to avoid this.
- Airport experience degrades. Late-night check-in, quieter lounges, restricted dining — the overall experience is less comfortable than daytime flying, and airlines compensate with lower fares.
- Onward connections do not exist. A midnight arrival rarely connects to an early-morning domestic flight the next day with any safety margin, so airlines cannot sell these seats to connecting passengers. They fill them with people who live near the destination airport and can go directly home, or price-sensitive passengers who will stay the night.
On international routes from India, the pattern is even more pronounced. Long-haul routes to Europe, North America and Australia often depart in the overnight window (10 PM–2 AM) from Indian airports. This is partly due to slot allocation and partly due to arrival timing at destination — a midnight India departure arrives in London or New York at a convenient morning hour. These slots are popular enough that they are not always dramatically cheaper, but they tend to undercut the premium midday-departure options by meaningful amounts.
The peak time slots — what to avoid if price is the priority
If the early-morning and late-night slots are the cheap end, the expensive end is typically:
- 7:30 AM–10:00 AM departures — the core business travel window. Heavily demanded, priced accordingly. On Delhi–Mumbai and Bangalore–Delhi, these can cost 40–80% more than the cheapest slot of the day.
- 5:00 PM–8:00 PM departures — the evening return window for people doing a same-day trip. Also expensive and often sold out earlier in the booking cycle.
- Friday departures in any popular leisure window (Friday 5–8 PM is the worst of both worlds — peak day and peak time).
Avoid these if you are travelling for leisure and price matters. The midday window (11 AM–2 PM) is often a reasonable middle ground — not as cheap as the extremes, but not as expensive as the peaks.
Making early-morning flights actually work
The reason most people avoid 5:30–6:30 AM flights is that getting to the airport on time requires leaving home between 3:30 and 4:30 AM depending on how far you live from the terminal. A few things that make this manageable:
- Book an airport hotel or transit stay the night before. On routes where the flight savings are ₹3,000 or more, staying at an airport hotel (typically ₹2,500–₹4,000 for a decent room near major Indian airports) still leaves you net positive. You sleep normally, walk to check-in, and start the day without the 4 AM alarm at home.
- Pre-check-in online. IndiGo and Akasa Air allow web check-in from 24 hours before departure. Pre-check-in the evening before so you arrive needing only to drop a bag (if any) — this cuts airport time dramatically.
- Have a plan for the first few hours at destination. Arriving at 7:45 AM in a city where your hotel check-in is 2 PM means you have time to kill. Book a day-use room, find a good coffee shop, or get to your first meeting early. Planning for this removes the frustration.
- Carry everything in cabin baggage. Early-morning slots are the least likely to experience baggage handling delays, but checking a bag still means waiting at the belt. A cabin bag lets you walk straight out.
Do these cheap time slots apply to international flights from India?
Partially. International departure timing is more constrained by slot allocation at the foreign destination airport and by the hours required for immigration and customs clearance. However, a few patterns hold:
- Overnight departures (10 PM–2 AM IST) from Delhi, Mumbai, Bangalore and Chennai tend to be competitively priced compared to mid-afternoon departures on the same route. This applies to Gulf routes (Dubai, Doha, Abu Dhabi) and Southeast Asia (Singapore, Bangkok, KL).
- Early-morning departures for regional routes (Chennai–Colombo, Kolkata–Dhaka, Mumbai–Kathmandu) follow the same domestic pattern — less convenient, lower priced.
- Long-haul to Europe and North America — departure timing matters less because you are on a nine-to-fourteen-hour flight regardless. Focus on the fare bucket and booking window rather than departure time for these routes.
One thing worth checking: on Gulf routes, airlines like Air India Express and IndiGo sometimes offer cheaper fares on the early morning departures from secondary Indian airports (Lucknow, Kozhikode, Mangalore) compared to similar slots from major metros. The combination of an off-peak city and an off-peak hour can produce meaningful savings.
Bottom line
If you can genuinely handle a 5:30 AM departure or a midnight arrival, those slots will consistently save you money compared to the convenient midday and evening departures. The inconvenience is the product — you are getting paid (in fare savings) to accept a time that most passengers reject. Whether that is worth it depends entirely on your schedule and how much sleep you are willing to sacrifice. For a ₹3,000–₹5,000 saving on a domestic round trip, it usually is.

Frequently asked questions
What is the cheapest time of day to book flights in India?
The cheapest departure slots (not booking time) are typically 5:30–7:00 AM and 10:30 PM onwards. For booking time, there is no universally cheapest hour, though checking on a Tuesday or Wednesday sometimes coincides with airline inventory adjustments that surface lower fares.
Are early-morning flights more likely to be on time in India?
Generally yes. Early-morning flights are the first rotation of the day for the aircraft, so there is no inherited delay from a previous flight. As the day progresses, delays accumulate across the network. This is an additional reason beyond price to prefer a 6 AM departure if your schedule allows.
How much cheaper is the 6 AM flight compared to the 9 AM flight in India?
On popular domestic routes like Delhi–Mumbai or Bangalore–Delhi, the difference is typically ₹800–₹2,000 on a given day. On days with high demand (pre-holiday, long weekends), the gap can widen to ₹2,500–₹4,000 because the 9 AM business slots fill first and push into expensive fare buckets.
Is a late-night international flight from India actually cheaper?
On Gulf and Southeast Asia routes, yes — 11 PM–1 AM departures from Indian airports tend to be in the cheaper end of the daily fare range. On long-haul routes to Europe and North America, overnight departure is the norm and the price differential by departure time is smaller — the booking window and fare bucket matter more.
What should I do if I book a very early flight and miss it?
Missed flights on cheap fares (Super Saver, Saver) typically mean you lose the ticket with no refund. IndiGo and Akasa may allow a same-day rescue booking at an additional fee, but at a high walk-up price. The safe approach for ultra-early departures is either to stay near the airport the night before or to book a Flexi fare that allows same-day changes.
