This is easily a self-contained airport, built from passenger suggestions for happy passengers. To emphasise on this, the entrance of Bangalore International Airport Limited (BIAL) (or Kempegowda International Airport) is shaped into a “smiling” curve, stressing their efforts to provide service with a smile. From the time the blueprints were being implemented, BIAL reached out to passengers for their recommendations. This was through a campaign titled “Smile Bengaluru”; and in 33 months the airport opened with self-checkin kiosks, self-swipe e-boarding pass, a day hotel, business centres, spa, retail outlets, restaurants and other such on-demand facilities.
