Point-to-point mileage calculator?
With the demise of UACNXN software where can I find a similar resource for true point-to-point mileage calculations for UA flights? I have an upcoming mileage run with the return leg being TPA-IAD-PDX, which as UA sums it, is 3137 miles and would require 7 500-miler UG certs. My guess is that it be 6 certs if the mileage were calculated point to point.
