Hi Cow,
I have six left but just used two to Columbia on two one ways, usually I'm using them for family long haul trips to S America and Asia with connects to smaller cities etc that don't work without priority. I pay revenue, family is on reward tickets. I also like to keep some Priority Rewards and a bunch of miles in reserve as it can save lots of money and hassle if you have a sudden plan change. Cheap award rather than very pricey last minute revenue. One reason Im looking at spending enough to re-qualify for SE again.
