Alaska Air Group reported net income of $289 million for the third quarter, and said that even after excluding a special one-time accounting change, its adjusted third-quarter net income of $157 million represents a company record.

The Seattle-based parent of Alaska Airlines and Horizon Air said its net income under generally accepted accounting principals was $4.08 a share, compared with $2.27 per share in 2012. With the accounting change excluded, its profit was $2.21 a share, Alaska said.

The company noted that a 20 cents-per-share dividend it paid last quarter was Alaska’s first in more than 20 years.

Its shares rose $2.65, or 4 percent, to close at $69.68 Thursday, a new high.
