Amex 15% Transfer Bonus to Avianca LifeMiles Ends March 28, 2026: Star Alliance Luxury Awards for Couples + ROI Calculator
Amex 15% Transfer Bonus to Avianca LifeMiles Ends March 28, 2026
Amex Membership Rewards is offering a 15% transfer bonus to Avianca LifeMiles through March 28, 2026. This turns the standard 1:1 ratio into a strong 1:1.15 effective ratio — every 1,000 Amex points becomes 1,150 LifeMiles.
For luxury couples this is one of the last high-value opportunities this month to book premium Star Alliance awards. You can redeem for Lufthansa or United business class to Europe, or Avianca business class to South America for two passengers at dramatically lower cost than cash fares on the same March 27, 2026 dates. The bonus applies automatically and stretches your points further while award availability and cash prices remain strong.
In this guide we break down exactly how the bonus works, run the numbers in an interactive ROI calculator with verified cash fares, and show which redemption wins for your travel style. All data is cross-verified across Frequent Miler, The Points Guy, Upgraded Points, Doctor of Credit, LoyaltyLobby, and official program sites as of March 27, 2026.
How the Amex 15% Transfer Bonus to Avianca LifeMiles Works
Amex Membership Rewards normally transfer to Avianca LifeMiles at a 1:1 ratio. With the 15% bonus active through March 28, 2026, the effective ratio becomes 1:1.15 — every 1,000 Amex points you transfer become 1,150 LifeMiles. The bonus applies automatically to every transfer completed before the deadline. Transfers are usually instant or same-day.
| Details | Value |

Pro tip: This is the last day of the bonus. Transfer today if you hold Amex points — the 15% boost disappears tomorrow night and LifeMiles remain one of the best Star Alliance programs for low taxes and wide award availability.
