ACMI? Polar? did I miss something again.... Blockspace agreement with DHL yes..
Yes, which is effectively ACMI, since DHL controls the schedule and assumes the fuel cost.
IMO, the "blockspace agreement" moniker is simply a tag to keep the regulators at bay, since I doubt DOT would like to have to admit that DHL has more than 25% "control" of the company, even though it has installed 2 top DHL execs at the top...
