Financial: Save those United Miles

So you have mileage plus miles that are expiring. An easy fix, if you have not signed up so far is Mileage Plus Dining. They say they will credit 250 miles, I'll let you know how quickly that happens. As a fall back you can always purchase miles from United, that is only suppose to take 48 hours to be credited. Note purchases from many merchants can take 4-6 weeks, or so they say.
