Anything booked less than 21 days before departure usually sees a sharp spike in pricing. Aim to finalize your booking at least 90 days out.

Booking flights to Delhi: The practical guide

Book your flights 3 to 4 months in advance to secure the best rates for Indira Gandhi International Airport (DEL). Use a combination of Google Flights for price tracking and book directly through the airline's website to simplify any necessary changes or cancellations.

Set up a Google Flights price tracker. Enter your departure city and Delhi (DEL) into Google Flights. Toggle the 'Track prices' switch. You will receive an email whenever the price for your selected dates drops significantly.
Compare full-service vs. low-cost carriers. If flying long-haul, stick to full-service carriers like Air India, Emirates, or Singapore Airlines for better reliability and baggage allowances. If you are already in Asia, low-cost carriers like IndiGo or AirAsia are fine, but ensure you buy 'flex' tickets that include checked bags.
Verify visa requirements before booking. Ensure your passport has at least 6 months of validity remaining and two blank pages. Do not finalize your purchase until you confirm you are eligible for the e-Visa, as non-refundable tickets are common.
Book directly with the airline. Avoid third-party aggregators (like Expedia or Kiwi). If a flight is delayed or cancelled, the airline will only provide customer support if you booked directly with them, not through a middleman.
