I have a video clip of my travel from the Bangalore City to the Bangalore International Airport. We can use the Volvo buses which are red in color. Its very easy and the frequency of these buses are very high. You need to pay INR 150 for a trip. The airport is of very high standards.

One difference that I had seen is that you do not need to do the baggage screening before checking in. The baggage screening is done by the airlines you travel. The airport has excellent Duty free shops and restaurants. The airport is also very spacious and well designed.
