IndiGo jumps to record high as HSBC boosts target to 6,650 rupees, citing tier 2/3 expansion, strong fares, and international growth potential.

• HSBC raises TP by 11% to 6,650 rupees, keeps "buy" rating amid tier 2/3 route strategy and healthy fares.
• Expanding in lower-tier cities limits exposure to low-yield routes with strong capacity and fare support.
• International growth benefits from experienced management, low unit costs, and a large domestic network.
