The transfer-bonus arbitrage for this program

- Amex MR: 2-3 active bonuses per month, 20-40% size. Common partners: BA Avios, Aeroplan, Virgin Atlantic, ANA, Delta.
- Citi ThankYou Points: 1-2 active per month, often Turkish + LifeMiles + Singapore KrisFlyer.

The cents-per-point framework
Calculate cents-per-point on every redemption: (cash value / points used) × 100. Decision rules:
- Below 1.0¢/point: Don't redeem. Pay cash; save points for better redemption.
- 1.0-1.5¢/point: Marginal. Other factors (flexibility, status earning) tip the decision.
- 1.5-2.5¢/point: Standard redemption.
- 2.5-4.0¢/point: Strong redemption (typical for Park Hyatt + aspirational hotels).
- 4.0¢+/point: Excellent (Lufthansa First via LifeMiles ~17¢, Cathay First via Alaska ~21¢).
For travelers without aspirational redemptions in mind, portal redemptions at 1.0-1.5¢/point provide a guaranteed minimum.
