The board meeting of the national flag carrier today increased the ceiling of amount that the chairman and managing director can spend for the maintenence of aircraft engine. "The board decided to increase the ceiling to Rs 300 million that the chairman can spend and Rs 270 million that the managing director can spend," said a union leader. Earlier ceiling was Rs 200 million only. "The engine of the one of the Boeing 757 -- that flies on the nternational route -- could now be brought back soon after its maintenence due to this decision. It is currently in Israel for the maintenence. The protesting Nepal Airlines Corporation (NAC) employees unions gheraued the head office of the NAC to force the board to take decision. However, they are still not satisfied due to board's reluctant on other pressing issues. "NAC board has seven directors but one director representing finance ministry was not present in the meeting today," the employee added. Of the two Boeing 757s, the NAC is flying only one aircraft reducing its international flghts to a half due to technical glitch in the engine of one of its aircrafts. The reduction in the number of international flights has hurt the national flag carrier as it is compelled to fly only three flights on its most profitable route Kathmandu-Kuala Lumpur and New Delhi. The ailing NAC has been long planning to buy two aircraft to add on its international route where there are more than two dozen international airlines are flying. Due to lack of aircraft the NAC has not been able to fly a direct flight to European country that could be the key to its existance.
