any recent experiences with this? I have a new passport and an old passport with a 10-year multiple entry tourist visa which expires on 17 March 2015.....my return flight out of India leaves on 10 February 2015.

I know airlines require you to have 30-60 days of validity, but I don't think that applies to VISAs as even the new India VISA processor says "Important: Travelers must leave India on or before the expiration of their visa."
