Air Transport Services Group, Inc. Reiterates Strong Liquidity Position.

WILMINGTON, Ohio -- Air Transport Services Group, Inc. (NASDAQ: ATSG), a diversified air cargo services company and parent of three cargo airlines, including ABX Air, today reiterated that its liquidity position remains strong, and that the Company expects to remain in compliance with the covenants of its senior debt facilities.

On May 28, 2008, ATSG said it was reviewing an announcement from ABX Air's largest customer, DHL Express, that DHL intends to reduce the number of ABX Air aircraft deployed in its U.S. express network beginning in July, and that DHL was negotiating with United Parcel Service (UPS) for an agreement to outsource to UPS most or all of the airlift and ground services currently provided by ABX Air.

Joe Hete, Chief Executive Officer of ATSG, said "Our preliminary view based upon what we know at this time, which we have shared with our principal creditors, is that our financial strength, marketable asset base and projected cash flow should allow us to remain in compliance with our financial covenants and required debt amortization under our credit agreements for the remainder of their terms. We look forward to updating the market on our outlook when more information about DHL's intentions becomes available."
