I think the farthest origin and destination are Mexico City and Punto Arenas, Chile using 20,000 OnePass miles for COPA and Avant Airlines. Nonstop distance is 5280 mi o/w or 10560 mi. RT. (8500 km o/w or 17,000 km RT) Actual flown mileage MEX-PTY-SCL-PUQ is 5840 one way and 11680 round trip, or 94120 km o/w and 18820 km. RT.
For grins I checked out BOS-Barrow, AK with CO via IAH and found it was 3380 mi. nonstop, or 5572 mi. o/w via IAH and ANC
