I booked with Aeroplan during the 'promotion' a month or so ago for flights in march. I am flying through Chicago on united to heathrow and then SAA down to Jnb and on to cpt. Return leg is on SAA to Munich, connect in Europe and back on scandinavian airlines to copenhagen and then sk on to Chicago and united to sea for the final leg from ord to sea. The key was finding low taxes on the business award ticket.
