It's all so confusing...??!!!!

Hello
Landed back on Sunday morning, our first holiday in UC... WOW...!!!!
I have caught the bug and would like to travel this way again if possible. We have booked a flydrive with Virgin Holidays and we are currently in PE both ways. Can I use the miles I have accumulated to upgrade to UC and if so, how do I go about doing this?
Sorry if this question has already been asked before. I did perform a search but to no avail. (maybe I should have entered in the right keywords..??[:w][}:)][:I][:I]
Any help gratefully received.
