Romanian airlines Tarom, Blue Air and Carpatair, with around 400m-euro cumulated turnover in 2009, together spend around 180m euros annually on aircraft maintenance, according to ZF calculations, which take into account average annual maintenance costs of 3m euros per aircraft. The three airlines operate 59 aircraft aged between eight and twelve years, with maintenance costs per aircraft ranging between 1 and 5m euros depending on the type of aircraft. Carpatair operates 18 aeroplanes (12 Saabs with a 50-seat capacity, three 105-seat and three 70-seat Fokkers) aged 12 years on the average. Blue Air has signed an acquisition contract for five Boeing 737-800 Next Generation planes, to be delivered by late 2013. Blue Air operates 15 aircraft. Tarom operates seven aircraft models (of the Boeing, Airbus and ATR class). Beside aircraft acquisition and maintenance costs, airlines spend another several million euros on salaries and pilot and flight attendant training. Almost 405 pilots and 548 flight attendants are working for the three companies, with the average salary of a flight attendant standing at 1,000 euros, while a pilot’s salary can go as high as 5,000 euros, according to market data.
