The service is more flexible than commercial air travel in that it is not bound to set routes, timetables or schedules. This flexibility can be very important in a wide variety of situations. For example, where EU meetings end up taking longer than originally expected it is vital that departure times can be altered as required at short notice. There are also frequent occasions on which Ministers may have to attend or return to attend important meetings or events in the State, such as Cabinet meetings, Dáil or Seanad Debates or Oireachtas Committees, and this is only possible by use of the MATS. The service helps Ministers to fulfil all of their duties, both at home and abroad, to the greatest extent possible.
