17 flights, including Africa.

Presumable BA/GB Airways in North Africa would be able to book and price this for me?

I believe you are only allowed 4 segments in each continent and you appear to have 5 in Asia and 9(!) within Europe...

Thanks, I overlooked that minor detail!

Therefore, I presume the following would be OK: -

CMN BA LON BA DXB BA LON BA BJS CX HKG CX CGK CX X/HKG CX BKK AY HEL AY LON BA TNG

Many thanks

Er, no - the other fundamental problem is that Morocco is part of Europe as far as these tickets are concerned, not Africa, so you haven't touched 3 continents. And note that you are only allowed two stopovers in the continent of origin. You'd probably need to go LHR-JNB-HKG or vv somehow...

Check this link. they have a downloadable routing/timetable /planner, which lets you plan correctly. It verifies all the applicable rules and also prices.
