LAX/BLR CX around $4K all in
Seeing a bunch of nonrefundable, but changeable with a heft fee, business class fares in October, for as low as $4041.76 AI. ITA did not pop this up.
E.g. 2 Oct outboond 13 Oct return.
I've found that the fare is bookable via phone call to a travel agent (HRG). Haven't tried Kayak or Orbitz as this was booked for business travel
