IndiGo is India's largest low-cost airline that has experienced rapid growth since starting operations in 2006. It focuses on providing affordable air travel to customers while maintaining high standards of operational efficiency and on-time performance. IndiGo utilizes various CRM practices like an online reservation system, call centers, and customer feedback mechanisms to manage customer touchpoints and loyalty. While IndiGo excels in areas like on-time departures, some customers note issues like expensive in-flight food and the need for improvements to the reservation website and customer rewards programs. The airline could enhance its CRM approach through initiatives such as a frequent flyer program, improved customer segmentation, and addressing needs throughout the customer lifecycle.
