OK this can't be right, can it? Will someone knock some sense into me?

I currently have 75,000 MR points. To purchase 85,000 more would be $2125 at $25 per 1000 points.

This means my wife and I can travel round-trip in UC for $2125.... where's the catch?

Does this seem like it makes sense, or have I been staring at these numbers for too long?

Thanks again,
Lewis
