Ancillary Revenue and Its Impact on IndiGo's Profitability

This study analyses the growing importance of non-ticket revenue streams for India's largest low-cost
carrier, IndiGo. Operating in a highly competitive, price-sensitive market, IndiGo faces limited margins
on base fares due to fluctuating fuel prices and regulatory constraints. Ancillary revenue, comprising
income from seat selection, excess baggage, in-flight meals, priority services, and strategic partnerships,
allows IndiGo to improve profitability while keeping ticket prices competitive. This study employs a
qualitative-descriptive methodology grounded in secondary data from IndiGo's annual reports, financial
statements, and aviation industry publications, supplemented by primary survey data from approximately
100 respondents. Findings show that ancillary services, while constituting only 9-11% of total revenue,
contribute an estimated 20-30% of total profit due to high gross margins of 60-80%. The study
establishes that demand is primarily necessity-driven, satisfaction rates exceed 93%, and spending
behaviour is moderate but predictable, confirming that ancillary revenue is a fundamental pillar of
IndiGo's business model.
