VS071 GLA-MCO Always Late!

I've been checking performance of this flight and so far it hasn't left on time, typically between 1 and 2 hours late
!
Why is this? they know the schedule, all they need to do is get the plane up from Manchester in plenty time. Also on VS website, it states that OLCI is currently unavailable, again, why would that be? (intend calling VS on that one), my real question for the experts on here was over the lateness.
I'm due to take this flight on the 25th of June, my flight is the first for a while where there is a flight coming in from MCO first (VS072), will this make a difference to the on-time performance?
Sorry, lots of questions and a bit of a rant, any explanations would be greatly appreciated.
