Qf440 - 2/11

[Adam.S]

Hi to all,
I had family on today's QF440, Melbourne to Sydney flight.
Apparently as halfway through boarding, passengers were asked deplane the aircraft (B734 - VH-TJY).
Some, if not all passengers from this flight were then asked to bored the next Qantas flight to Sydney, QF442 (B763).

Just curious, can I ask if it is known what happened to the original QF440 flight. Was the aircraft declared U/S?
It was suggested there was an issue with the airconditioning?

Cheers.


**update**
QF440 departed MEL approx 90mins behind schedule.
Still, any known reason for the delay would be appreciated.
