Route question-travelling to Hyderabad

Hi to all the gurus!
I may have to make a business trip to Hyderabad in November. There are no direct flights from the UK, and since I'd like to go with VS if possible (i.e. get the VS350 to BOM), I was wondering about transfers and internal flights from Mumbai to Hyderabad. Which Indian carrier is best, and what's transfer/facilities like for domestic? Otherwise I may have to go Emirates via DXB or Lufthansa from Frankfurt.
Anyone have experience of Hyderabad travel?
