Business the play 72,000 pts Singapore Airlines via SIN (one stop), Saver
72,000 Saver for SQ business both legs through Changi — the crown from Chennai as from Delhi. It's the only program here whose price doesn't fall with the shorter South-India distance, and it still lands cheapest. Cash J ₹2.5–4L; the network's best ₹/mile from India.
Feed it: 72,000 HDFC Reward Points (1:1) · 36,000 Axis EDGE Miles (1:2) · 1,44,000 Amex Membership Rewards (2:1)
Cathay Pacific via HKG (oneworld), Standard award
91,000 for the ~6,710-mile Cathay journey via HKG — same Zone as Delhi (the band is wide enough to swallow the difference), and the same seat Qantas books at 125,400. 19,000 over KrisFlyer's SQ business. The Hong Kong value read when Standard space shows.
Feed it: 1,82,000 Amex Membership Rewards (2:1) · 91,000 SBI Travel Credits (1:1) · 4,36,801 RBL Reward Points (4.8:1 via Club ITC → Marriott Bonvoy)
Singapore Airlines via SIN — Velocity Reward Seat
89,500 for SQ business via Singapore — Chennai's ~5,728-mile total drops it a band below Delhi's 104,000, the lowest business figure across all four corridors. ~₹20,700 carrier charges. Cheapest via KrisFlyer→Velocity 31:20 or Accor 1:1 — but the Velocity account may be closed to Indians and ticketing is unverified. On paper the winner; KrisFlyer 72,000 is bookable today.
Feed it: 89,500 HSBC Reward Points (1:1 via Accor Live Limitless (ALL)) · 2,14,801 Amex Membership Rewards (2.4:1 via Marriott Bonvoy) · 4,29,601 RBL Reward Points (4.8:1 via Club ITC → Marriott Bonvoy)
Cathay Pacific via HKG (oneworld) — Partner Classic Reward
125,400 for Cathay business via HKG (Partner Zone 7) — 34,400 above the identical Asia Miles seat and impractical to fund from India: ~100,320 Accor points at the 4:5 exit. The Hong Kong hub priced the Qantas way, i.e. the expensive way.
Feed it: 1,00,320 HSBC Reward Points (1:1.25 via Accor Live Limitless (ALL)) · 62,700 Axis EDGE Miles (1:2) · 1,25,400 SBI Travel Credits (1:1)
Economy the play 27,000 pts Cathay Pacific via HKG (oneworld), Standard award
MAA–HKG–SYD is ~6,710 combined miles — Cathay's 5,001–7,500 Standard band, 27,000 one-way on CX metal via Hong Kong (total-distance chart). Chennai is a confirmed Cathay port. Surcharge-clean at this length; Standard space is the constraint. SBI feeds Asia Miles 1:1.
Feed it: 54,000 Amex Membership Rewards (2:1) · 27,000 SBI Travel Credits (1:1) · 1,29,601 RBL Reward Points (4.8:1 via Club ITC → Marriott Bonvoy)
Singapore Airlines via SIN (one stop), Saver
Chennai is in KrisFlyer Zone 6, Sydney in Zone 9, so the India→Australia through-award is the flat 35,000 Saver one-way — the flat zone price means South India pays exactly what Delhi does, undercutting the distance-based rivals that Chennai's shorter feed would otherwise reward. SQ serves MAA nonstop; issuers feed KrisFlyer 1:1.
Feed it: 35,000 HDFC Reward Points (1:1) · 17,500 Axis EDGE Miles (1:2) · 70,000 Amex Membership Rewards (2:1)
Singapore Airlines via SIN — Velocity Reward Seat
Chennai's shorter feed drops MAA–SIN–SYD (~5,728 mi) into Velocity's 4,801–5,800 band — 42,000, one band under Delhi's 50,000 — plus ~₹6,900 SQ carrier charges. The distance dividend Chennai gives the distance-based programs. Funded via KrisFlyer→Velocity 1.55:1, but Indian account eligibility is unsettled; treat as unconfirmed.
Feed it: 42,000 HSBC Reward Points (1:1 via Accor Live Limitless (ALL)) · 1,00,801 Amex Membership Rewards (2.4:1 via Marriott Bonvoy) · 2,01,601 RBL Reward Points (4.8:1 via Club ITC → Marriott Bonvoy)
Cathay Pacific via HKG (oneworld) — Partner Classic Reward
The ~6,710-mile CX journey via Hong Kong prices on Qantas' Partner Zone 7 (5,801–7,000 mi) at 51,800 — nearly double Asia Miles' 27,000 for the same seat. Qantas has no Indian card feed (Accor 4:5 is the least-bad on-ramp). A completeness row, not a buy.
Feed it: 41,440 HSBC Reward Points (1:1.25 via Accor Live Limitless (ALL)) · 25,900 Axis EDGE Miles (1:2) · 51,800 SBI Travel Credits (1:1)
