NEW YORK (TheStreet) -- Shares of Alaska Air (ALK) - Get Report are increasing 0.8% to $69.35 on Tuesday morning as the company announced plans for a codeshare agreement and frequent flier partnership with Japan Airlines.

Industry experts have said Alaska Air is an attractive partner for Asian airlines that are seeking extra revenue from connecting passengers to flights in the U.S., after the company agreed to acquireVirgin America (VA) for $2.6 billion last month, Reuters noted.

The agreement between Alaska Air and Japan Airlines will be effective June 29, pending government approval, the Seatac, WA-based airline said.

Codeshare flights allow air carriers to market a route together, which lets them expand their network and helps fill planes, Reuters added.

Separately, TheStreet Ratings Team has a "Buy" rating with a score of B+ on the stock.

The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures, impressive record of earnings per share growth, compelling growth in net income and expanding profit margins.

Although the company may harbor some minor weaknesses, the team feels they are unlikely to have a significant impact on results.
