- Book about 3–6 weeks ahead for most domestic routes.

- July–September (except holidays) is usually the cheapest season; Diwali and December–January are the most expensive.
- Early-morning and late-night flights are often cheaper.
Domestic flights in India are among the cheapest in the world, but prices on the same route can easily double depending on when you book and when you fly. Here's how fares behave — and how to use that to pay less.
How far ahead should you book?
For most domestic routes, the sweet spot is about 3–6 weeks before departure. Book much earlier and you rarely save more; book in the last 7–10 days and fares climb quickly as cheaper fare buckets sell out. For holidays such as Diwali, Christmas–New Year or long weekends, book 2–3 months ahead.
Cheapest days to fly
- Tuesday, Wednesday and Saturday departures are usually cheaper than Friday and Sunday, when business and weekend travellers fly.
- Early-morning and late-night flights are often priced lower than convenient daytime slots.
- Search a few days either side of your date — a one-day shift can save hundreds of rupees.
Cheapest and most expensive months
| Period | Fares | Why |
|---|---|---|
| July – September | Lowest | Monsoon low season for most leisure routes (except Ladakh and some hill routes) |
| January (after New Year) – March | Moderate | Pleasant weather, but no big holidays |
| April – June | Higher on hill routes | Summer holidays to the mountains, Ladakh and Kashmir |
| October – December | Highest | Diwali, the wedding season, Christmas and New Year |
Smart ways to save
- Compare, don't guess — prices differ between airlines and booking sites. Our flight search compares many at once.
- Check the total price — hand-baggage-only fares look cheap until you add check-in baggage and seats.
- Try nearby airports — Goa has two (GOI and GOX), and Bagdogra (IXB) serves Darjeeling and Sikkim.
- Round trip vs two one-ways — sometimes two one-way tickets are cheaper.
- Book on a Saturday — Gen-Z travellers can earn ₹50–₹400 back with Gen-Z Cashback Saturdays.
