                              FOR IMMEDIATE RELEASE

                           ARKANSAS BEST CORPORATION'S
                            FIRST QUARTER EARNINGS IS
                     $0.41/SHARE, NET INCOME INCREASES 135%;
                        ABF(R)'S OPERATING RATIO IS 95.5%


         (Fort Smith, Arkansas, April 25, 2005) -- Arkansas Best Corporation
(Nasdaq: ABFS) today announced first quarter 2005 net income of $10.5 million,
or $0.41 per diluted common share. For the first quarter of 2004, net income was
$4.5 million, or $0.18 per diluted common share. Arkansas Best's first quarter
2005 revenue was $417.3 million compared to $374.8 million in the first quarter
of 2004.

ABF FREIGHT SYSTEM, INC.(R)

         ABF Freight System had first quarter 2005 revenues of $384.1 million, a
per-day increase of 11.0% versus first quarter 2004 revenue of $346.1 million.
First quarter 2005 operating income at ABF was $17.2 million compared to $8.7
million during the first quarter of 2004. ABF's first quarter 2005 operating
ratio was 95.5% versus an operating ratio of 97.5% during the first quarter of
2004.

         ABF's total tonnage per day increased by 3.7% during the first three
months of 2005 compared to the same period last year. This consisted of a 2.9%
increase in LTL tonnage per day and a 6.7% increase in truckload tonnage per
day. "Although year-over-year LTL tonnage level increases slowed throughout the
quarter, ABF improved its first quarter operating ratio by two percentage points
compared to last year's first quarter," said Robert A. Young III, Arkansas Best
Chairman and Chief Executive Officer. "During the quarter, ABF benefited from a
combination of firm pricing and additional tonnage to produce improved operating
margins."

         Through the first twenty-one days of April, average daily tonnage
figures in ABF's LTL business are slightly ahead of last year.

         Billed LTL revenue per hundredweight was $26.28, an increase of 7.2%
over last year's first quarter figure of $24.52. "The LTL pricing environment
remains competitive and is consistent with last year. We think overall pricing
is still good," said Mr. Young. ABF's first quarter 2005 LTL weight per shipment
was flat compared to the first quarter of 2004. First quarter 2005 LTL length of
haul declined by 2.0% compared to the first quarter of 2004.




Decreases in length of haul cause revenue per hundredweight to decrease. First
quarter 2005 LTL freight density decreased by 2.0% compared to the first quarter
of 2004. Decreases in freight density cause revenue per hundredweight to
increase.

         Billed truckload revenue per hundredweight increased by 10.7% over last
year's first quarter figure. "Because of capacity constraints in the truckload
industry, ABF continued to add truckload shipments at good prices and acceptable
margin levels," said Mr. Young. "While maintaining its primary emphasis on
service to its LTL customers, ABF will seek to add these larger shipments when
they contribute to overall profitability."

         "ABF's first quarter 2005 city pickup and delivery productivity was the
same as that of the first quarter of 2004. Yard productivity improved over last
year's first quarter," said Mr. Young. "Though ABF's first quarter
bills-per-hour dock productivity was below that of the same period last year, it
exceeded the dock production levels of the fourth quarter of 2004 and was equal
to that of the third quarter of 2004. As new dock workers added last year have
become more familiar with their job activities, dock handling efficiencies have
improved."

CLIPPER

         Clipper's first quarter 2005 revenue was $23.5 million, a 12.2%
increase over first quarter 2004 revenue of $20.9 million. Clipper's first
quarter 2005 operating ratio was 100.1% compared to a 2004 first quarter
operating ratio of 102.8%. "Clipper's results improved significantly during the
first quarter which is historically the least profitable quarter of the year,"
said Mr. Young.

         "Clipper's temperature-controlled division experienced a 23.6% revenue
increase and a substantial reduction in last year's first quarter operating loss
due to continued success in its dedicated fleet activity and emphasis on
improving the profitability of individual customer accounts," said Mr. Young.
"An increase in first quarter revenue of over 80% in Clipper's brokerage
division was associated with improved service by Clipper's trucking partners and
an increase of available loads that would normally move on the rail. Compared to
last year's first quarter, Clipper's intermodal division experienced reductions
in both revenue and operating profit, primarily due to substandard service
provided by the railroads."

AUCTION RATE SECURITIES

         In early March, accounting industry guidance became available to
Arkansas Best regarding the financial statement classification of auction rate
securities held as temporary investments.




This information clarified that auction rate securities should be classified as
investment securities instead of cash and cash equivalents.

         Arkansas Best invests in auction rate securities as part of its cash
management strategy. Arkansas Best has historically classified these investments
as cash and cash equivalents because of the short length of their interest rate
reset periods (90 days or less) and because of the ability to sell them each
time their interest rates are reset. In fact, these auction rate securities are
liquidated when Arkansas Best has a need for cash.

         Arkansas Best has reclassified auction rate securities as short-term,
temporary investments. As a result of this reclassification, cash flows from
investing activities now include the investments and sales of auction rate
securities. This reclassification has no impact on previously reported total
current assets, total assets, working capital position, results of operations,
or financial covenants and does not affect previously reported cash flows from
operating or financing activities.

         Arkansas Best had $38.5 million invested in auction rate securities at
December 31, 2004 and $70.6 million invested in auction rate securities at March
31, 2005.

PENSION

         Arkansas Best's pension expense will be $10.0 million for the full year
2005. This compares to full year 2004 pension expense of $9.5 million.

EXPENSING OF STOCK OPTIONS

         On April 14, the Securities and Exchange Commission ("SEC") announced
an amendment to the required compliance dates for the Financial Accounting
Standards Board's new rule regarding the expensing of the fair value of stock
options. Arkansas Best previously disclosed that in the third quarter of 2005,
it would begin expensing the fair value of stock options. As a result of the
April 14 SEC ruling, Arkansas Best will now begin expensing the fair value of
stock options in the first quarter of 2006. The estimated negative impact, in
each quarter of 2006, of prior unvested stock option grants will be
approximately $0.01 per diluted common share, net of estimated tax benefits.

RESTRICTED STOCK

         On April 20, 2005, Arkansas Best Corporation granted 178,550 shares of
restricted stock under the 2005 Ownership Incentive Plan which was approved by
shareholders on April 20, 2005. The fair value of the shares granted is Arkansas
Best's closing stock price on the date of the




grant. The restricted stock grant vests at the end of a 5-year period beginning
on the date of the grant. Arkansas Best will begin expensing this restricted
stock grant in the second quarter of 2005. The estimated negative impact of the
grant will be approximately $0.01 per diluted common share, net of estimated tax
benefits, per quarter through the vesting period.

COMMON STOCK PURCHASE

         During the first quarter of 2005, Arkansas Best made open market
purchases, totaling 37,650 shares, of its common stock. The total purchase price
for these transactions was $1.5 million. These common shares were added to the
company's treasury stock. Since February 2003, as a part of a previously
announced program to repurchase up to a maximum of $25 million of its common
stock, Arkansas Best has purchased a total of 509,150 shares totaling $13.9
million. Arkansas Best plans to continue making open market purchases of its
stock on an opportunistic basis.
