Witnessed a beauty the week before last. Bad weather had delayed the last Virgin Blue flight to sydney. As we were waiting in the departure lounge, Jetstar announce their flight to sydney will be cancelled due to curfew.
The virgin ground staff make a PA explaining that if people take too long to board, the flight may be cancelled due to the curfew.
The cabin crew re-iterated the message in a friendly way during boarding, and after take off the captain came on the pa and thanked the cabin crew and the passengers for the 'team' effort of boarding so quickly.
From the time the beacon switched off to the time the safety demo finished as we were taxying out for take off - a total of 21 minutes had elapsed on a full 737-800.
We landed 4 minutes before curfew kicked in.
