I was just talking to a friendly knowledgable agent (yes they do exist) at the worldperks RTW award desk who brought my RTW dreams crashing down when she said that a world perks rtw award trip is limited to 29,000 miles.
When you purchase a RTW, there are 3 levels. The cheapest is for trips under 29,000 miles, then 34,000 miles, then 39,000 miles. Each level has a price. I thought it was the same for awards, but I've never done a RTW award.
