All VS planes are maintained to the highest standards and I do not believe there is a general issue with mechanical issues against the age of the planes causing any greater reliability issues over the 747s or the A346. Even the A330's go tech and they are only a year or so old.
Just look at the Dreamliner - a brand spanking new plane that has issues a plenty. Just reading today that LOT are cancelling flights on the Dreamliner even after the recent battery fix.
As I have already said, VS works its fleet hard and all it takes is for one plane to be delayed for it to have knock-on consequences on the schedule.
Those delays can be for all sorts of reasons - yes occasionally mechanical but more likely to be weather related, ATC or even due to passenger action (medical and yes even diversions for bad behaviour). I read in an earlier post that the flight from DXB generally forms the YVR flight once it arrives at LHR and I know that there are runway restrictions at DXB at the moment so that may be causing problems as well.
These happen to all airlines and I honestly don't believe that these affect VS anymore (in proportion) than say BA ( but I don't think VS have left an engine cowl unlatched or had a spanner sucked into an engine on the ground like BA have had), DL, LH, QF and even FR !
That said perhaps VS should look at the timing of the YVR flight if the inbound that appears to be the plane for it is often late from its starting point and adjust it accordingly to provide a more realistic schedule. Now some might think that is simply massaging the schedule to make the on time arrivals look better but surely the issue is having a realistic schedule that people can rely on.
