Colegate:
Why is the proposed 4/week frequency hopeless for business travellers? Bombay isn't exactly a there-and-back in a day destination. I would have thought most business travellers could work their schedule around a 4/week choice of flights. A more important negative point could be that regular travellers already have frequent flier programs with BA, VS or EK, and Bombay is currently BD's only Asian destination.
VS already operate A340's on the route, so an A330 isn't very different in terms of capacity (pls correct me if I'm wrong on this).
Personally, I'll stick with EK - wonderful food and service, despite the break in journey in Dubai.
