Change in VS073

Hello all
I know its a bit sad but I'm flying on VS073 on 31st October and take an interest on the flightpath. Over the summer the course has been quite direct, out over Ireland and hitting land over Kennedy Space Centre area (See 10th Oct for an example)
However, yesterday I noticed that the course had changed dramatically, flying further North and down over Canada and central America. It was a lot further, but would be great for the views (See 12th Oct for detail)
Todays flghtpath also seems to be taking the Northerly route.
I'm also aware that on the 31st when we fly the departure time has been pulled forward to 12:30 from the usual 14:05. Whats driving the change in flightpath, is it weather or just a winter route ?
