London/Cambridge?

I think I have enough points with Virgin Atlantic for a trip to England. Well, one way and out of New York. But this one-way, from New York flight would only cost $113.50 (taxes and surcharges). I flew with Virgin Atlantic a lot during my year at Cam but never realized I had enough miles because they have a Spend Miles option and a Reward Flights option. I thought they were the same. They aren't. I have enough miles with the Spend Miles option. I guess this option has restriction on dates while the Reward Flights don't. Anyway, maybe I'll fly back to Cambridge for a few days in June. Most of the people I met at Cam were first years so they're all graduating this year. This would be the last chance I get to see them before they all go separate ways!
