Door-to-door time estimate (real world)

 

  1. At least 90–120 minutes before departure at the airport for domestic flights (if you have checked bags, or during busy hours arrive 2 hours). Airlines typically allow online check-in 24–48 hours before and close counters ~60 minutes before departure; boarding gates often close ~20 minutes prior. IndiGo+1

  2. Flight airborne time: ~2h45–3h. Direct Flights

  3. After landing: 15–40 minutes to disembark + baggage claim (if checked).
    So expect 4–6 hours total from leaving home in Delhi to exiting Chennai airport (varies with your travel time to/from airports, traffic, baggage, and how early you arrive).

When fares are lowest — practical rules (India)

  • Book domestic flights about 3–6 weeks before departure for good deals; some analyses suggest ~7–8 weeks is often very safe for consistent savings. Midweek bookings (Tuesday/Wednesday) and midweek travel (Tues/Wed) often show lower fares. Skyscanner+1

  • Cheapest travel windows: avoid peak festival periods (Diwali, summer holidays, Christmas–New Year). Shoulder months (Jan–Feb, Sept–Oct) often have lower demand. Skyscanner+1 

  • Last-minute: sometimes airlines drop unsold seats, but this is unreliable — last-minute is a gamble. Skyscanner

How to find & book the cheapest reliable fare — step-by-step

  1. Compare across search engines: start with Google Flights / Skyscanner / Kayak to view price trends and times. Set a price alert (these sites send email/push when price changes). Google+1

  2. Check airline sites after you find a fare: sometimes booking direct (IndiGo / Air India / Vistara / SpiceJet) gives extra flexibility, seat/meal options and easier refunds. Air India

  3. Book mid-week if possible: Tuesdays/Wednesdays often have lower published fares. travelxp.com

  4. Use incognito or clear cookies if you repeatedly look up the same itinerary (some believe dynamic pricing changes with repeated searches). (Useful but not guaranteed.) The Times of India

  5. Use cashback / rewards cards or bank offers when booking. Check if airline/aggregator has coupon codes or credit-card partner discounts.

  6. For very low cost: be flexible on time of day (red-eye / very early morning often cheaper).

  7. Buy baggage separately only if cheaper — always compare total price (ticket + baggage + seat selection) before finalizing.

Booking checklist (before you hit “Buy”)

  • Confirm baggage allowance and fees (varies by fare class/airline).

  • Check cancellation/refund rules; low-cost fares may be non-refundable.

  • Enter passport/ID exactly as in your ID (Aadhaar/Passport) for domestic travel.

  • Save booking reference and take screenshot of e-ticket + boarding pass when available.
