Flying Sydney to London via Tokyo with Qantas and JAL - will points from the JAL ticket be credited to our Qantas frequent flyer account?

Hi,

We recently booked return business class airfares to London, flying Qantas from Sydney to Tokyo and then British Airways (via a JAL ticket) from Tokyo to London.

We are already Qantas Frequent Flyers. Will the JAL ticket credit to our QF account or should we look at signing up for a different program prior to that flight?

Yes. As all flights are one world. Just make sure your qantas number is attached to the booking.  It will also appear on your boarding pass if you have given it correctly
