WASBLR -

What an interesting option! I did find some good PE flights on AF going from DTW->BLR.

The only real issue is timing, flights from BLR to PNQ are much more sparodic, I would get in at 1am to BLR and the first flight to PNQ is at 8am ugh ! And that would be after a 5 hour layover in CDG. There are just no easy answers dang it !
