According to the Anglo-Dutch multinational travel management company, the On the Go app "loads itinerary details for all bookings, plus alerts and real-time updates about flight schedules relating to travelers' specific itineraries and detailed local weather information." The enhancements follow "extensive dialogue with our clients." ATPI
introduced the mobile app in spring 2012 with a simple flight search feature and in September 2012
updated it to include full flight booking functionality.
