I just did a speculative transfer to JAL this morning with Bilt. Received 315k JAL for 140k Bilt using the 125% Bilt Cash buy-up.
Our friends have been dying to take us to Japan for a while so I expect we will use it for that. Otherwise I like what I see from their partners (LATAM, cheaper BA award flights, Air France, Alaska, etc). I don’t think we will have any issues draining that balance.
