Airlines flying routes on prohibited days
 

I will ask my question here, as it is not directly related to the AirAsia incident, but I have just heard on the BBC that AirAsia was not licensed / allowed to fly the Surabaya - Singapore route on Sundays, and have been duly censured for this by the Malaysian authorities...

How is it possible for an airline to fly a presumably scheduled route on a day on which they should not have been? Simple pax here, but such a flight must require hundreds of things such as check-in desks with staff, baggage handlers, fuel, catering, a flight plan, a slot, dammit! plus many others which I am omitting or simply know nothing about. I'm stunned, all this was laid on, planned, and nobody raised an eyebrow?

I had no idea about this- Do other airlines do this? Does it happen often? Is it a "local" thing? I'm honestly baffled :confused:

Thanks to any who can shed light on this :ok:
