Its an open secret for us in Whitefield area by now. There is this scenic route that skirts around city's mad traffic and takes you to BIA in an hour, any time of the day! The drive is just under 60 km, point to point. However, listen to this, last 18 kilometers are spent circling around BIA only because there is no entry to the airport from the East side. Some pictures for you, and the route map as well. Basically, you go from Hope Farm junction to Hoskote, on to Budigere, and then to the airport via a village just north of it, or via Devanahalli itself which is much further north of the airport.
