Yeh, I forgot JL only flew to Delhi. You could do JAL to Delhi and Air Sahara to Bombay. Personally, I would stick with what he had, but there are other options.

A ticket through Asia is just booked as two tickets and comes to 5k more miles.

Edited to correct myself, it's actually 15k more miles. For inexplicable reasons, 60 + 90 came to 140 earlier.
