Looks like I may be doings some MRs this fall, found a couple of days in November, pulled the trigger on an overnight RT PAE-SAN in F. Still on the fence if I will actually need the miles, end up making the trip.
This is correct. So on a PAE-SAN run I earned an extra 1081 miles. It didn't double COS.
