Hi All! I am booking a flight through the Chase UR portal and am using a mix of cash+points. I'm wondering what chart mileage accrual goes by when the actual ticket cost is not known. I'm not even sure of the fare class of my ticket as this isn't shown either. I know these types of bookings are eligible for mileage accrual on other airlines, just wondering about the particular rules for JAL.

Thanks in advance!

Sam
