Later this year, in October, I have to fly BOS-BLR-BOS and my options are somewhat limited to AF via CDG or BA via LHR. There's also an outside chance that I may be able to chose LH via FRA or EK via JFK/DXB but my company does not have a corporate deal for either EK or LH.
If given a choice, I would chose EK just so I don't have to change planes in Europe in the middle of the night. I really like the long haul sector between JFK and DXB where I can get a full night of sleep, and I like arriving at BLR at 5pm instead of the very late night arrival of the Euro carriers.
So my questions are these: Between AF, BA, LH, which airline has the best business class product to BLR? Do any of these carriers have inflight wi-fi between Europe and BLR?
