In the flights section, why is this getting listed twice for each flight?
FlightAware gets its data from the FAA. On this flight, it appears that the FAA controls the aircraft from ANC to a handoff to Canadian controllers. The Canadians then hand it back to the FAA when it arrives in US controlled airspace. Hence, you have two flight plans for the same routing.
