I Don’t Know United’s Award Rules

I've got a thriving Award Booking Service. I hold myself out as an expert on the nuances of award-booking rules, and yet I don't know United's award booking rules. Let me explain.

On February 10, 2011, someone believed to be a United employee posted on FlyerTalk that the new routing rule for United awards would be that the actual routing you choose can exceed MPM by no more than 15%.

For those who don't know: MPM (Maximum Permitted Mileage) is the maximum length that a routing on a paid ticket between an origin/destination city pair can be.
