City pairs like SYD-LHR are well below 11000 miles as it is based on great circle mileage between the O&D, not the sum of miles required for the specific routing flown. The new chart led to much speculation of new destinations such as JNB which could create new city pairs being more than 11000 miles apart using the great circle.
