Capital One is running a 25% transfer bonus to Japan Airlines Mileage Bank through April 30, 2026. This promotion brings the effective transfer ratio to 1,000 Capital One miles = 975 JAL miles — closer to 1:1 than the standard 4:3 ratio (750 JAL miles per 1,000 Capital One miles).
This is the third transfer bonus to Japan Airlines Mileage Bank since it became a Capital One partner in September 2025. Normally, transfers to JAL operate at a 4:3 ratio, but the 25% bonus increases the output to 975 JAL miles for every 1,000 points transferred.
Capital One cards that earn 2x miles per dollar spent will effectively earn 2.5 JAL miles per dollar during this promotion (2 miles × 1.25 bonus). This could be useful for booking premium cabin flights to Asia or leveraging JAL’s award chart for partner flights, such as oneworld airlines like American Airlines.
There is no minimum transfer amount, but consider your redemption strategy before moving points — transfers are typically irreversible. This bonus may appeal to travelers targeting specific JAL awards or looking to optimize their Capital One miles balance.
