I believe there are a lot of factors that go into the decision of which airline to fly to India. I have always flown DL/KL/AF as it's one stop to BOM/DEL, and it let's me accrue my miles on my dominant airline. I'm also traveling for business and find the accommodations to be more than adequate. Would Emirates/Etihad/Qatar be better? Perhaps. But flying SkyTeam gets me to where I'm going in one stop versus two stops on the ME3 for some of the US cities I come from/go to. Bottom line...a number of factors go into the decision.
