JL raised their fuel surcharge
again on June 1 and their fuel charges are somewhat steep. I don't know if CX has been regularly charging JL fuel surcharges on CX issued tickets.

The link in this thread to the info about the new surcharges is in Japanese but you can see the old surcharge went as high as 175000JPY and now can be as high as 250000JPY.
