Qf31/32 On-time Preformance And Load Factor

[QantasA380]

Hello,

 

I am flying on QF2 LHR - SYD on april 16th and flying QF1 SYD-LHR on april 29th.

 

I have seen lately the QF31 is alot delayed, is there any reason for it? Monday ( 02-20 ) it arrived 6 hours late...

 

Also, what whould be the load factor on the A380 from LHR to SYD?

 

Thank u
