AirAsia was limited slots due to nearing it’s quota for flying people to Singapore
Fox News reports:
"So AirAsia has committed a violation of the route that has been given to them," Barata told The Wall Street Journal. He said the company's flights from Surabaya, Indonesia's second largest city, to Singapore had consequently been suspended on Friday.
AirAsia used to have permission to fly the route daily, but the number of slots was cut for the period Oct. 26 to March 28 because the country was nearing its quota for flying people to Singapore, said Indonesia’s acting director general of aviation Djoko Murjatmodjo. He didn’t say if other airlines also had their slots reduced.
Murjatmodjo added that AirAsia had been flying the route on Mondays, Wednesdays, Fridays and Sundays rather than the four days designated by the Transportation Ministry. He said the ministry is investigating why AirAsia was flying the route outside its permitted schedule. The probe will include an investigation of the ministry.
"Frankly speaking, it's a bit late for us to find out about this," he said. "One thing that's certain is the days that they are flying aren't the same as the days they were given. There was no request for changes."
