Kolkata's best-priced exit, and the corridor that exposes Maharaja's hub bias: the April-2026 chart gives CCU ten routes and exactly one international (Kathmandu), so the flat 12,000-point SE-Asia tier every other metro enjoys never reaches Bengal. Thai doesn't care — its Zone-3 chart prices Kolkata identically to Delhi, which makes 27,500 miles in Royal Silk on the shortest India–BKK nonstop the richest per-mile business redemption on the network. Aeroplan wants 1.7× Thai's own chart for the same seat.

All-in ₹ = points × the program's house value (valuation index) + the sourced one-way surcharge; a dash means the carrier doesn't publish it and the ranking counts it ₹0 — the row's note carries the caveat. “Dynamic” rows never compete for the play. Feed-ins come from the same transfer data as the optimizer, multi-hop chains included.
The same 27,500-mile Royal Silk rate Delhi pays, on a flight 800 miles shorter — per flown mile, the best business redemption ROP sells to India. HDFC (2:1), Axis (1:2), HSBC (1:1) and SBI (1:1) all feed ROP; mind the hard 3-year expiry and TG metal only.

CCU–BKK's 1,016 flown miles sit comfortably in the 0–2,500-mile Pacific band CardExpert prices for Delhi–Bangkok — 47,500 after the June-2026 hike (was 40,000). Surcharge-free, but 1.7× Thai's own 27,500 for the identical seat: only for points already stranded in Aeroplan.

Kolkata sits in the same Zone 3 (India) tier as Delhi on the direct-flight chart — 17,500 miles for a 1,016-mile hop that cash prices at ₹7–12k. Skip economy; the chart's value lives one row down.

IndiGo flies CCU–BKK nonstop and BluChips knock rupees off the fare at roughly ₹0.40–0.60 apiece — no chart, no sweet spot, no expiry. On a ₹7–12k cash corridor that's a coupon, and an honest one.
