American Airlines, which is being eyed by rival US Airways Group for possible takeover, plans to boost international flying and increase U.S. codeshares under a plan to emerge from chapter 11 protection, Reuters reported yesterday. American parent AMR Corp is also looking to generate $3 billion in financial improvements by 2017, including cost cuts and revenue growth, it told employees in a memo on Monday. To reach $1 billion in revenue improvement, its goals include boosting international flying to 44 percent of business by 2017 from 38 percent currently. Domestic flying would drop to a 56 percent share in five years.
