Award route card · one-way
IndiGo runs the Kolkata–Saigon nonstop and prices it off the live fare. Fixed awards mean a Malaysia detour through KL: Avios at 22,500/43,000 per-segment, AAdvantage's flat region at 25,000/40,000 on a Bonvoy 3:1 chain. Vietnam sits east of Air India's Kolkata reach, so Maharaja's flat SE-Asia tier is absent — the same Bengal blind spot as Bangkok and KL.

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.
40,000 AA miles business via KL — 120,000 Bonvoy at 3:1 (see /transfers/to/american-aadvantage). A touch under the 43,000 Avios sum for the same routing; useful only if Bonvoy is your one road to a flat bed.

CCU–KUL (1,638 mi, Z3, 24,500 J) + KUL–SGN (653 mi, Z2, 18,500 J) = 43,000 Avios for Malaysia business via Kuala Lumpur. A flat bed to Saigon, but the KL routing dips south and back up; IndiGo's nonstop is the faster ride if you'll fly economy.
Feed it: 43,000 HDFC Reward Points (1:1) · 86,000 Amex Membership Rewards (2:1) · 43,000 HSBC Reward Points (1:1)
CCU–KUL (Z3, 12,500) + KUL–SGN (Z2, 10,000) = 22,500 Avios via KL. A backtrack for a route IndiGo flies nonstop; the fixed price exists but rarely beats cash on this corridor.

25,000 AA miles Indian Subcontinent → Asia Region 2 (Vietnam) — 75,000 Bonvoy at 3:1 (see /transfers/to/american-aadvantage), via KL on Malaysia. Flat region price with a stop added to a nonstop corridor; the backstop, not the play.
Feed it: 75,000 Amex Membership Rewards (3:1 via Marriott Bonvoy) · 1,50,000 RBL Reward Points (6:1 via Club ITC → Marriott Bonvoy) · 25,000 Axis EDGE Miles (1:1 via Club ITC → Marriott Bonvoy)
IndiGo flies CCU–SGN nonstop and BluChip tracks the fare (~₹0.40–0.60/point, min 500, own metal only) — no chart, no plan. The only nonstop points option on a corridor no chart carrier serves direct.
