Now ain't that just simply astonishing. Polar customers, Polar freight, on Polar scheduled service one day and then with a flick of the magic wand, SHEZAMM, out of the smoke and mirrors, the same freight just magically arises out of the dust cloud as Atlas freight. Just frigging amazing.
What's so amazing about it? That's simply the way Scheduled Service works: An airline offers a service to Freight Forwarders. The Freight Forwarders consign freight to the airline to be moved. Until that consignment, the freight "belongs to" the Freight Forwarder, not the airline. It wouldn't matter if you replace "Atlas" with "Kalitta" or "Southern" -- the airline doesn't "own" the freight until it is consigned by the Freight Forwarder; the airline doesn't "own" the route unless it has been given exclusive rights to the city pairs by the countries involved.
So, Polar withdraws from a market. Atlas gets the appropriate approvals and enters the market. The Freight Forwarders consign their freight to Atlas. The ONLY "magic" thing about the deal is that "Polar" and "Atlas" happen to be the same people at the top.
