ditto here - keep getting an error every time I try link my membership rewards to my qantas frequent flyer account it fails. I tried for three days now, and gave up and created a new Qantas FF# and that worked without a hitch. Now I just need to merge the two... (anecdotally my old FF# was 7-digits long, the new one 10-digits - all other info is identical from one profile to another)
