I have two friends currently visiting family in Darwin. They were supposed to fly home to Brisbane yesterday, specifically planned to avoid the rush over the next few days as school holidays end.
Yesterday they were advised by Jetstar that their flight had been cancelled. They have been rebooked on a flight next Tuesday - supposedly the next available flight! They are lucky that they have family to stay with in the Territory, but the other 160-odd pax may not have that 'luxury' as they endeavour to find their own accommodation for 6 nights.
