Business the play 50,000 pts Air India via DEL (Star Alliance) — no AI nonstop from Kolkata
India–Singapore business went 42,000 → 50,000 in April 2026 (the Chennai–Singapore example on the chart). More points than KrisFlyer's 45,000 AND a Delhi connection — SQ's nonstop is the honest premium buy here; Maharaja's case lives in economy.

Singapore Airlines nonstop, Saver (Zone 6 chart)
45,000 Saver post-Nov-2025 (up 5% from 43,000). The redemption four Indian issuers exist to feed, on the shortest sector it's sold for — book the 355-day window; Saver space ex-CCU is thinner than ex-BLR.

Economy the play 12,000 pts Air India via DEL (Star Alliance) — no AI nonstop from Kolkata
The April-2026 chart's flat 12,000-point SE-Asia tier names Singapore explicitly and prices by zone, not metro — but ex-Kolkata that means doubling back through Delhi. Verify the connecting itinerary prices at the flat zone rate before transferring.

Singapore Airlines nonstop, Saver (Zone 6 chart)
Zone 6 (India, Sri Lanka, Maldives, Bangladesh) Saver — cut 5% to 19,000 in the Nov-2025 rejig, no fuel surcharges. Kolkata pays the same as Bengaluru for a flight an hour shorter; with IndiGo nonstop on the route, cash fares often win in economy.

IndiGo nonstop — BluChip, dynamic (revenue-priced)
BluChip has no award chart — chips offset the live fare at roughly ₹0.40–0.60 apiece (min 500), own metal only. IndiGo's CCU–SIN nonstop is the corridor's cash-fare governor; BluChips are a discount on that fare, not an award.
