I have an International Priority parcel being shipped by FedEx from Zurich, Switzerland to Perth, Australia.
Currently the parcel is located in Singapore, I presume with FedEx at Changi Airport. It is scheduled to be delivered by 1700 on 09 October (GMT+8). The parcel (tracking #771679606750) is showing in tracking at Singapore since 0636 05 October (GMT+8).
From what I can see on FlightAware and Flightradar24 there are no scheduled FedEx Express flights from Changi to Australia, at least up to Wednesday 07 October as I can't see past that date.
This raises the question given the parcel is scheduled to be delivered by 09 October (GMT+8), if FedEx uses other airlines for parcels, or for International Priority parcels?
Note that Sydney is the usual point of entry for FedEx, and Perth is a day's flight from Sydney, and another day for distribution at Perth.
