•THE Air Corps operates two planes for ministerial transport duties: a Gulfstream IV and a Learjet 45.
•The Gulfstream, bought by the government of Charles Haughey in 1991, can carry 14 passengers on long-haul flights.
•The seven-seater Learjet cost €8m in 2004 and is used for flights in Europe.
•Former Taoiseach Bertie Ahern complained of the Learjet: "It has its faults because one cannot stand up and it does not have a toilet."
•The Department of Defence calculates the average total per hour cost of flying the Gulfstream at €3,790. The hourly cost of the Learjet is estimated to be €4,200.
•In 2009, Enda Kenny -- while in opposition -- criticised the government for using the jet to fly ministers Mary Coughlan and Willie O'Dea to Texas for crisis talks on the future of the Limerick Dell plant at a cost of more than €164,000. He said that business-class flights would have cost around €1,000 each.
