What do you know, BMTC has gotten savvy enough to print brochures containing timetables for the Airport Volvo routes and hand it out to interested folks.
I picked one up on the BIAS 7A on my way to work today, and that because a fellow passenger was asking the conductor if there was a timetable. On my own it would never have occurred to me to imagine that fancy stuff existed. Here are the scanned images - click on them if you can't read it.
Missing is BIAS 1 which goes to Gottigere, down Bannerghatta Road. There doesn't seem to be any routes numbered 2 0r 3 - funny I never noticed this before.
