Transfer American Express Membership Rewards Points to Air France-KLM Flying Blue, Get a 25% Bonus

Why It Matters

The promotion creates a limited‑time boost in value for Amex points, encouraging cardholders to redeem for premium airline tickets and driving higher engagement with both Amex and Flying Blue’s loyalty ecosystem.

Summary

American Express is offering a 25% bonus on Membership Rewards points transferred to Air France‑KLM’s Flying Blue program through June 30, 2026, with a minimum transfer of 1,000 points and a maximum of 999,000 points. The bonus effectively reduces the cost of award flights, making a 60,000‑mile business‑class ticket to Europe require only about 48,000 Amex points and a 45,000‑mile business award drop to 36,000 points. Transfers are usually immediate but may take up to 48 hours, and once moved the points cannot be returned to Amex. Flying Blue miles expire after 24 months of inactivity, so members must fly or meet other activity criteria to keep the miles alive.
