FedEx 2Day is actually 3 days to Sitka
Wiper Haus is located in Arizona, 1710 nautical miles from the Sitka airport. Obviously there are no direct flights from Phoenix to Sitka, so a much longer trip via hubs in required. Your wiper blades will fly from Phoenix to a FedEx hub in Memphis or Oakland, and then on to Anchorage. From Anchorage a feeder airline will carry the FedEx packages to Sitka. Because the packages travel about 4000 nautical miles over 3 flights it takes an extra day to get packages to Sitka versus the rest of the country.
