The Challenge
IndiGo, India's largest airline by market share, faced several challenges in a highly competitive and price-sensitive market:
- Limited customer loyalty in a price-driven market
- Need to increase ancillary revenue beyond ticket sales
- Fragmented customer data across multiple systems
- Lack of personalized engagement with frequent flyers
- Desire to create additional revenue streams through partnerships
Industry Context
The Indian aviation market is one of the fastest-growing in the world, with intense competition driving ticket prices down. In this environment, airlines must find innovative ways to differentiate and create customer loyalty beyond price.
