Air21 finished fifth in the classification phase but pulled huge upsets over the San Miguel Beermen and the Talk 'N Text Phone Pals in the Wild-Card and Quarterfinal rounds, respectively. The Express lost in six games to the Purefoods Chunkee Giants in the semifinals, but won a one-game match for third-place over the Barangay Ginebra Kings, their best finish in franchise history.
