Gardyloo,
Thanks for your information and reminders.

headinclouds,
with that in mind the LHR-DOH,CAI-MAD-(x)SCL-IPC-SCL-AKL-SYD-CNS-NRT-HKG-PEK,DEL-HKG-JNB-VFA-JNB itenerary doesn't work; violates rules for more than 2 flights in origin region. But thanks for the idea. I could change the order of the European/Middle East stuff to make it fit but I'm trying to avoid the wintertime in Europe. Hmmm...
