Nowadays travelling to Bangalore from Chennai, by flight is not time-saving anymore. The new Bangalore Airport is more than 1:30 Hours from the city and on top of you have 1 hour of security checks and queues. So I prefer train travel, to go to Bangalore from Chennai and when you travel by a train you can reach directly into the city.
Today I had to go to Bangalore and I couldn’t get a ticket in Shadabthi Express, so I had to resort to flight. With my frequent flyer points in Jet Airways, I got a free ticket and thanks to the reduced fuel prices I had to pay only Rs.450 as taxes. Reaching Bangalore I skipped the taxi service and took the Air-Conditioned Vayu Vajra buses to the city. It was very comfortable and affordable at Rs.150 from New Airport to HAL III Stage (Old Airport). You have a friendly crew on the bus, racks in front at comfortable heights to store your big bags and good ambience with FM music. Overall I highly recommend taking the bus to and from the new Bengaluru International Airport.
