Award route card · one-way
The shortest international flight out of Kolkata — and, surprisingly, one no award chart reaches. Biman, US-Bangla and IndiGo split the nonstop; none is a oneworld or Star carrier, so the cheap Avios Zone-1 you'd expect on a 149-mile hop simply doesn't exist, and Air India flies no metal to detour onto. IndiGo's BluChip tracks the fare; everything else is a cash ticket. Honest absence, not a gap in our data.
Every economy option on this corridor is dynamic-priced — no honest number to crown. The rows below say what we know.
| Program | Metal / routing | Points | Surcharge | All-in ₹ | vs play |
|---|---|---|---|---|---|
| IndiGo BluChip | IndiGo nonstop — BluChip, dynamic (revenue-priced) | dynamic | — | — | — |
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.
IndiGo flies CCU–DAC nonstop and BluChips offset the fare at roughly ₹0.40–0.60 apiece (min 500), own metal only. Biman and US-Bangla fly it too but neither runs an Indian-feedable program, and no oneworld or Star carrier is on the route — so no Avios band, no partner award. On a one-hour, low-fare hop that's fine: it was always a cash flight.
