So I took the Kingfisher First flight from LHR to BOM, and I must say I was impressed.
Great seat, good food (not great though), excellent wines, overall a good touch and feel. Flight left gate in London 20 mins early (!) and arrived almost 1h early in Mumbai! The flight attendants were attentive, though not quite the Bollywood cast I was expecting after some of the enthusiastic comments elsewhere. But very polite indeed!
Conclusion: Will fly them again if I have the chance.
