How to Use AU Bank Credit Cards to Secure Up to ₹4,500 Off Your IndiGo Flight Booking

If you hold a credit card from AU Small Finance Bank and are planning to fly with IndiGo, here’s a solid offer to consider: you could get an instant discount up to ₹4,500 on your flight booking when paying with your AU card. Let’s break down how it works and how you can maximise the benefit. ✅ What You Need to Know The discount applies when you use your AU credit card to book flights on IndiGo’s official platform. You must meet certain booking value thresholds (e.g., higher for international vs domestic tickets) to qualify for the maximum discount. The offer is sharper for premium AU cardholders and/or higher value bookings—smaller bookings may fetch a smaller discount. Transactions must meet the eligible fare class and booking channel. The discount appears instantly at checkout when the conditions are satisfied—so you see the benefit immediately. 💡 Pro Tips to Maximise Value Aim for bookings that hit or exceed the booking value threshold for the highest discount (₹4,500). If you travel internationally or have high-fare trips coming up, pay with your AU card to capture the maximum value. Read the offer’s fine print: verify which bookings (one-way/round-trip), which fare types, and which AU card variants are eligible. Book sooner rather than later—promotional offers often have fixed validity or limited allocation. Combine this discount with other travel deals (e.g., fare sales, partner discounts) to stack savings even further.
