Chennai Airport has metro station directly connected to airport terminals with walkalator etc. Opposite is Tirusulam local railway station. In front of airport one corner you have 2 city bus stops. Other side of the road you have TNSTC buses originating from airport to Trichy, Villupuram etc.
What do we have in Bangalore airport? AC buses to city. Hourly AC buses to Mysore. That's all. Why not normal regular Non AC Karnataka Sarige buses to any other part of Karnataka/ neighbouring AP TN (Hosur, Salem, Anantapur, Tirupati, Chikkaballapura, Doddaballapura, Tumkur, Hassan, Chitradurga, Davanagere etc).

more... getting down at Bangalore airport will take hours to reach bus stand or railway station to catch bus/ train to his destination. ЁЯдФ
