PRNewswire -- Dollar Thrifty Automotive Group, Inc. (NYSE: DTG) today announced that based on preliminary results, it expects total vehicle rental revenues for the first quarter of 2009 to increase approximately 2 - 3% compared to the fourth quarter of 2008, as rental revenues for the first quarter were favorably impacted by an approximate 10% increase in rate per day, more than offsetting an approximate 7% decline in transaction days. Additionally, rental revenues for the first quarter of 2009 are projected to be down approximately 8 - 9% compared to the first quarter of 2008, as an approximate 4% improvement in pricing on a year-over-year basis did not fully offset an approximate 12% decline in transaction days. The Company noted that the Easter holiday fell in the second quarter this year versus the first quarter in 2008, and February 2009 had one less day than February 2008.
