I have already made 2 trips to India this year (BOM) both on Qatar business,
I like the idea of getting a lot of sleep on the ATL-Doh leg, lounge is wonderful at DOH, nice showers etc, and then the remaing journey to BOM seems quite short.
The only draws backs are arriving at 2am to BOM and leaving at 4am back to DOH
but overall I like it better than the BA connection out of LHR
