How to Find Cheap Flights from Delhi to Mumbai?

To find cheap fares, it’s important to book strategically. Here are some practical tips:

1. Book in Advance

Airfares tend to rise as the travel date approaches. Ideally, book your tickets 3–4 weeks in advance to lock in lower prices.

2. Use Fare Comparison Websites

Use platforms like Skyscanner, Google Flights, MakeMyTrip, or Cleartrip to compare prices across airlines. They often highlight the best time to book or alert you when fares drop.

3. Be Flexible with Dates and Times

Flying mid-week or during off-peak hours (late night or early morning) can often result in cheaper prices. Avoid Fridays and Mondays if possible, as these days are popular with business travelers.

4. Look for Deals and Coupons

Sign up for airline newsletters or follow them on social media to get alerts about flash sales, promo codes, or cashback offers.

5. Use Points or Credit Card Rewards

If you have accumulated travel points through a loyalty program or a travel rewards credit card, redeeming them can help offset the ticket cost.
