Why Indigo Credit Card Applications Get Rejected: 5 Key Reasons

IndiGo has issued co-branded credit cards through HDFC Bank for the past two years and more recently with Kotak Mahindra Bank. At first glance the cards appear reasonable, but real-world use exposes several frustrating limitations.

Speaking with an existing Kotak–IndiGo cardholder highlights why these cards are unlikely to perform as well as they could. Below are five key reasons:

1. Too many conditions

Earning and redeeming rewards on these cards comes with multiple restrictions that complicate the experience. Examples include:

1. Points taking 90+ days to be credited to the 6E Rewards account.
2. Points cannot be used to cover the tax portion of a flight ticket.
3. Welcome vouchers include their own usage limits and exclusions.

The Kotak cardholder I spoke with reported that points often take longer than 90 days to appear. There may be further hidden conditions as well. All these caveats add friction and mental overhead — not ideal for cardholders who value simplicity.

2. Non-attractive rewards

:: Regular spends: A flat 2% earn rate on non-IndiGo purchases is low for an airline co-branded card. Competing airline cards, especially the premium variants, commonly offer higher base rates — often closer to 5% on relevant categories. A stronger earn structure, even on a pay-to-play premium card, would make the offering more compelling.

:: IndiGo spends: The advertised 6% on the 6E Rewards XL card sounds attractive, but it applies only to the base airfare. Charges such as airport fees, GST and convenience fees are excluded, so the effective benefit is lower than the headline rate.

Redemptions follow the same limitation: 6E Rewards can only be used against the base fare, which reduces the practical value of the accelerated earn rate.

3. Non-transparent rewards

The card’s rewards posting process lacks clear transparency. On Kotak-issued IndiGo cards, cardholders may not see a straightforward breakdown of how many points were earned for each transaction. This opacity makes it hard to verify earned value and assess the effective reward rate.

Without clear transaction-level details or an accessible explanation of the earning formula, customers cannot easily confirm whether points are calculated correctly. That uncertainty undermines trust in the program.

4. No elite perks

A premium airline co-branded card should appeal to frequent flyers by offering elite-style benefits. Surprisingly, IndiGo’s XL tier lacks common premium perks such as:

• Complimentary preferred seating
• Complimentary meals or vouchers
• Priority check-in or fast track security
• Access to any 6E Prime features
• Meet-and-greet or similar premium services

The absence of these benefits makes it harder for the card to attract frequent or premium travellers who might otherwise switch from competitor airlines.

5. No USP

Taken together, the card behaves much like an ordinary cashback card limited to IndiGo purchases, but wrapped in complex terms and conditions. There’s no clear unique selling proposition that sets it apart from generic cashback options.

For example, a consumer can get a straightforward 2% cashback to the card with other products and combine occasional promotional coupons from travel portals such as Cleartrip to beat the practical value of IndiGo’s offering. Without a distinct, easy-to-understand advantage, there’s little incentive to adopt the co-branded card.

Final thoughts

Historically, airline cards that arrive with heavy restrictions and unclear value propositions struggle in the market. Banks have had to revisit such products and simplify terms to make them appealing. If IndiGo and its banking partners are willing to rework earn rates, expand redemption flexibility and introduce genuine elite benefits, the cards could become worthwhile. Without those changes, they are unlikely to leave a lasting impression.
