IndiGo
IndiGo is effectively the whole corridor, and BluChip has no chart — redemptions track the live fare at ₹0.40–0.60 per BluChip, minimum 500, taxes and convenience fees cash-only. There is nothing to plan around: the "award" moves 1:1 with the ticket price. When Air India puts Group metal on Hyderabad–Kolkata, the corridor gets its anchor.
Estimate IndiGo BluChip is revenue-linked ~Rs0.50/pt; ~= typical one-way IndiGo economy fare / Rs0.50 for ~750 mi - a rupee offset that moves 1:1 with the live fare. Own-metal only, no partners.
