Air Transport Services Group announced that its aircraft leasing subsidiary, Cargo Aircraft Management, has agreed to purchase two Boeing 767-300ER freighters that ATSG’s airline subsidiary ABX Air currently leases from Guggenheim Aviation Partners. CAM expects to pay Guggenheim $49.9m for the freighters in transactions expected to close at the end of the third quarter. ABX Air operates them under two multi-year operating leases from Guggenheim that end during 2015 and 2017, respectively. Both are deployed with ABX Air customers. ATSG also received an option to purchase one more Boeing 767-300 freighter from Guggenheim in 2015.
