The document describes advertising opportunities on airport shuttle buses that transport passengers between domestic and international terminals at Mumbai Airport. Buses have approximately 800 square feet of advertising space on their exterior in the form of vinyl wrapping on windows and metal surfaces. Shuttle buses run every 30 minutes, transporting passengers between terminals located 5 km apart, with a journey time of around 20 minutes. Airport shuttle bus advertising allows brands to directly target both domestic and international flyers with visibility and messaging as passengers travel between terminals.
