Its about a month or two since the BIAL started off operations, and we have a handful of cab services that now ferry people up and down to and from the aiport. Of these two are appointed by the BIAL as official cab providers - Meru cabs (080 - 4422 4422) and Easy cabs (both seem to be from mumbai).
Both these providers have sourced Mahindra Logan cars from M & M in large quantities and I strongly believe this is the right option as the car is very spacious which is the most required thing for a weary traveller commuting miles together and for hours together. With a big boot, it only adds more value to use this car than perhaps any other car!
Add to this that these are chaffeured by drivers who wear proper uniform and are properly trained to behave with (weary) travelers and that the cars themselves have GPS so that they can be tracked for their subsequent assignments or in general on their whereabouts, and this makes the proposition of using these services pretty hassle free and safe. I heard that these cars have the option of automatically messaging the control room and getting deactivated if the drivers hoodwink customers in any way. I want my readers to confirm this though!
While these services are more point to point, there are two other services that are multipoint to airport on a sharing basis that costs a person just Rs.300/- onwards making that an even better proposition, barring the fact that the safety may be at question. Airlift and Zoom airport express services are two providers working on the sharing model and while the former operates innova cars, the latter uses tata winger cars for commutes.
