Overview
- The limited-time offer runs from February 1 to 28, 2026 for U.S. Capital One customers moving miles to Japan Airlines Mileage Bank.
- Capital One’s standard 4:3 transfer rate improves to an effective 1,000:975 with the 30% bonus, bringing it close to a 1:1 conversion.
- Among the major transferable currencies, only Capital One partners directly with JAL, though Bilt Rewards also supports transfers to Mileage Bank.
- Mileage Bank members can access award space 360 days out and tap favorable partner award charts, including oneworld and select partners such as Air France and Emirates.
- Given JAL’s family-only redemption policy and the challenge of accumulating its miles, analysts caution against speculative transfers.
