ATSG REVIEWING DHL RESTRUCTURING ANNOUNCEMENT

WILMINGTON, OH - May 28, 2008 - Air Transport Services Group, Inc. (NASDAQ:ATSG) said today that itssubsidiary ABX Air is reviewing DHL’s announced plan to restructure its U.S. operations and to pursue negotiations tooutsource its domestic air network to UPS.

“DHL informed us last night that, starting in the third quarter, it intends, as part of a series of cost-reduction programs, toremove from its U.S. air network 39 of the 55 DC-9 aircraft that ABX Air has dedicated to DHL,” ATSG Chief ExecutiveOfficer Joe Hete said. “In addition, DHL has notified us that it has commenced negotiations with UPS that could lead tothe assumption by UPS of substantially all of the services that ABX Air currently provides to DHL.

“We cannot now determine whether those negotiations will lead to an agreement, or what other steps DHL might considerto reverse its losses in the U.S.,” Hete said. “In the meantime, we intend to continue to perform under our currentagreements with DHL, while aggressively pursuing our strategy of expanding our business with other customers, basedon the technical and cost advantages of our fleet of advanced Boeing 767 cargo aircraft.”

ABX Air has been DHL’s principal business partner in the United States since August 2003, when it became anindependent publicly held company as its former parent, Airborne Express, was acquired by DHL. The relationship isgoverned by two commercial agreements, an Aircraft, Crew, Maintenance & Insurance (ACMI) Agreement that continuesthrough August 2010 and a Hub Services Agreement that runs through August 2009.

Together, those agreements provided approximately $280.8 million, or 74 percent of ATSG’s consolidated revenues, and$4.0 million, or 64 percent of its pretax earnings, for the first quarter of 2008. According to ATSG, the removal of 39 DC-9sfrom DHL service would reduce ATSG’s annual revenues from expenses subject to markup, and pretax income, byapproximately $80 million and $2.5 million, respectively. Based solely on DHL’s planned reduction of 39 DC-9 aircraft fromABX Air’s fleet, ATSG estimates that not more than 500 flight, aircraft maintenance, and support positions of theapproximately 10,000 total positions at ABX Air would be affected, by the time that fleet reduction is completed.

The ACMI agreement with DHL includes a put provision that gives ABX Air the option to retain or to sell back to DHL anyaircraft removed from DHL’s network, at the lower of book or fair market value. All 55 DC-9 aircraft currently have a netbook value of approximately $19 million.

DHL informed ABX Air that the reduction in its U.S. air network, which includes aircraft operated by other carriers, isexpected to begin in July and continue for 12 to 18 months. It said it may seek to operate some of ABX Air’s Boeing 767aircraft in its network for extended periods. Currently, ABX Air provides 55 DC-9 and 31 Boeing 767 aircraft, along withrelated flight crews, maintenance and technical services employees, in support of DHL’s domestic package network. Itsfleet includes 11 other 767s available for service to other customers.

ATSG said it expects to continue to serve DHL outside the U.S. market through its extended family of air cargobusinesses, along with its more than 30 other customers.

“We are disappointed that DHL has chosen not to pursue alternative means to improve its competitive position in the U.S.overnight delivery market,” Hete added. “While we look forward to further discussions with DHL about its plans, at thesame time, we reserve the right to pursue all means at our disposal to assure that, at minimum, DHL fully honors itsobligations under our existing commercial agreements with them.”

Hete also noted that “ABX Air’s management team, working in tandem with our other ATSG companies, is alreadyexamining alternatives for deploying our DHL aircraft with other customers, and other business options that wouldmaximize the return on our investments and the capabilities of our employees. Those options may include services for customers in the U.S. and around the world in markets where demand for efficient, flexible air cargo and related servicescontinues to expand.”
