The transfer has to be from the Member's 2009 Use Year allotment into
your 2009 Use Year allotment
OR their next following Use Year
allotment which would be their 2010 points into your 2009 Use Year if
your trip will happen during the date range of their 2010 Use Year.
You are allowed 1 transfer each Use Year so you can have points
transferred into your 2009 Use Year & if those transferred points aren't
past their banking deadline then you may bank them over to 2010 and
then in your 2010 Use Year you can get another transfer of points in
for that Use Year which would give you then
2 sets of transferred points in 2010 (the banked 2009 UY transferred points & the points
transferred into 2010 UY) .
As other posters here have said it's important to keep in mind that
even though you may bank transferred points those transferred points
still keep their original Use Year month & Home Resort affiliation.
Best wishes & hope it all works out
