You can use miles to insure loss of them.

Everyone probably knows about Award Guard, advertised on this website and mentioned in the above post. However, I learned that milepoint.com offers a discount for 2 year coverage. It's only $107 and 5,350 miles. That's less of a sting than the usual $214 (and no miles).
