Here is the joint-statement from Civil Aviation Authority of Singapore and Changi Airport Group:
INDONESIA AIRASIA SURABAYA-SINGAPORE SERVICE
In response to media queries, we would like to explain that before an airline can launch a service between two points, it needs to obtain approval of its flight schedules from the respective civil aviation authorities at each end of its flight routing separately.
The airline's application will be considered by each civil aviation authority, taking into account the air traffic rights available under the relevant air services agreements (ASA) and the availability of airport takeoff and landing slots from the respective slot coordinators.
On the Singapore end, Indonesia AirAsia had applied to operate a daily flight between Surabaya and Singapore for the Northern Winter Season from 26 October 2014 to 28 March 2015, arriving at Changi Airport at 8.30am and departing for Surabaya at 2.10pm.
These daily flights were approved as there were available air traffic rights under the bilateral ASA and the slots at Changi Airport were available.
Indonesia AirAsia was operating the flight four times a week on Mondays, Wednesdays, Fridays and Sundays. Airlines may adjust their flight frequencies in the course of a season in response to market demand or operational requirements.
Doomed AirAsia flight schedule unauthorised: Indonesia
JAKARTA - The AirAsia plane that crashed last weekend was flying on an unauthorised schedule, Indonesia's transport ministry said Saturday, adding it had now frozen the airline's permission to fly the route.
Flight 8501 crashed into the Java Sea with 162 people on board en route from Indonesia's second city Surabaya to Singapore early Sunday, at a flight time that had not been cleared by officials, said director general of air transport Djoko Murjatmodjo.
"It violated the route permit given, the schedule given, that's the problem," he told AFP.
"AirAsia's permit for the route has been frozen because it violated the route permit given." He said the permit would be frozen until investigations were completed.
A statement from transport ministry spokesman J.A. Barata said AirAsia was not permitted to fly the Surabaya-Singapore route on Sundays and had not asked to change its schedule.
Search teams have narrowed their hunt for the plane's fuselage and remaining bodies from the crash of the Airbus A320-200, with foreign investigators helping to pinpoint its black boxes, crucial to determining the cause of the crash off the island of Borneo.
