Looks like for authorities, the distance of BIAL from city was not so killing and they have introduce more hazards for travelers, tool both would mean more cost and time, unless what I see in pic here gets demolished.
Air travel overheads are taking over air fares for sure now, calculate this'
1. Cab fare to airport Rs 600 from MG road (approx) / Volvo fares are Rs 150
2. PSF - passenger service fee
3. UDF - User development fee
4. Tool booth
ha ha....I am sure this list would have new entries by this time next year....
