When to buy, how far ahead to book, and which months are cheapest — the complete data-backed guide.
This window gives the best mix of low fares and seat availability for domestic Indian routes. Booking sooner than 6 weeks rarely yields extra savings.
Tuesday and Wednesday departures are typically 10–20% cheaper than Friday and Sunday. Search mid-week days for the lowest base fares on your route.
August and September (monsoon) are India's cheapest flying months. Avoid December, April, and October when fares spike 40–80% above baseline.
