(FORT SMITH, Ark., January 30, 2008) — ABF Freight System, Inc.^®, the largest subsidiary of Arkansas Best Corporation (Nasdaq: ABFS), announced today that it has reached a tentative collective bargaining agreement with the International Brotherhood of Teamsters (IBT) for a new five-year labor agreement. Under the tentative agreement, ABF’s Teamster employees will be covered by the National Freight Industry Standards Agreement which is currently being ratified. This new agreement will replace the National Master Freight Agreement which expires on March 31, 2008.

“We have come to a labor agreement with the IBT well in advance of the expiration of our current contract,” said Robert A. Davidson, President and Chief Executive Officer of Arkansas Best and ABF. “This new contract provides us with greater labor flexibility and will allow ABF to more effectively serve the competitive LTL market, particularly the growing regional market.”

As a result of this labor agreement, ABF will continue to participate in, and contribute to, all of its current multi-employer pension plans. Going forward ABF will continue to evaluate, with the IBT, these plans and other solutions for providing secure benefits to its employees.

ABF Freight System, Inc., Arkansas Best’s largest subsidiary, has been in continuous service since 1923.
