I suddnely have a need to go various places that fits neatly into a clircle-kinda trip, and wonderes what kind of fares I should look for; my schedule takes me from OSL, through LHR, NBO, possible JNB/CPT, then I need to get to SIN and if possible HKG, before going back home. What kind of fare could make this more pelasant than a lot of single tickets?
