The transfer bonus for Rent Day (March 1, 2026 only!) is as follows:
Bilt Cash Upgrade: Members can use Bilt Cash to temporarily upgrade their status for $135 and access a higher tier promotion. Platinum Members will have an upgrade offer of 125%. Note: Members can only access one tier up (i.e., Blue → Silver).
JAL is a very worthwhile program, with its main drawback being that miles “hard expire” in 36 months, meaning that you can’t extend them, and that you cannot book an award until you have had your JAL Mileage Bank account open for 30 days (or just 7 when you link via Bilt or Capital One).
If you can find any JetBlue Mint flights, that would be one of the best possible use of the bonus – but the JAL / JetBlue partnership ends March 31st, 2026 so only transfer for this purpose if you find space that day.
Beyond that, we have an entire guide to JAL Mileage Bank here.
