I'm trying to put together my first RTW itinerary so please excuse my "rookieness". This would be my first leg from Europe to Africa:

LHR-(overland/LCC)-AMM-(overland)-CAI-LHR-NBO--Asia

Now I know you can only have 2 stopovers in the first continent. I can only see one route into NBO and that is from LHR. So my question is for the segment CAI-LHR-NBO, can it be specified that LHR is only a transit stop and not a stopover? If not, is there an LCC that would has either route CAI-NBO or AMM-NBO?

Also, are there any route from NBO out to either India or Thailand (for the Asia leg)?

Thank you in advance and I apologize if these questions have been asked before.
