InterGlobe Aviation Limited (INDIGO.NS): How It Works

• Core revenue mix: passenger services are the primary revenue driver (about 90-92% of total revenue).
• Passenger revenue components: passenger tickets contribute ~86% of total revenue and ancillary services ~12% (baggage fees, seat selection, meals, priority boarding, etc.).
• Cargo: IndiGo CarGo and bellyhold freight contribute roughly 2-8% of total revenue.
