     SEATTLE — Alaska Air Group, Inc. (NYSE:ALK) today reported second quarter net income of $17.4 million, or $0.56 per diluted share, compared to a net loss of $1.7 million, or $0.06 per diluted share, in the second quarter of 2004.

     Second quarter results include a restructuring charge of $14.7 million ($9.2 million, net of tax, or $0.28 per diluted share) for employee severance and related costs resulting primarily from the subcontracting of the Seattle ramp service function in May 2005.

Without these items, and excluding aircraft impairment charges of $37.2 million ($24.7 million, net of tax, or $0.92 per share) in the second quarter of 2004, net income would have been $24.7 million, or $0.74 per diluted share for the second quarter of 2005, compared to net income of $8.2 million, or $0.31 per diluted share in the second quarter of 2004.
