Also under appeal is an earlier court decision to block JetBlue and American Airlines Group Inc.'s (AAL) Northeastern Alliance, also on grounds that it would stifle competition. JetBlue's board will expand to 13 directors with the additions of Lynn and Miller following its annual meeting, "12 of whom are expected to be independent," the company said. Fueled by the recent investments, JetBlue's stock has soared 17% this week, compared with 1.5% gains for the U.S. Global Jets ETF JETS and contrasting with a weekly loss of 0.4% for the S&P 500 index SPX. In the past 12 months, however, JetBlue shares are off 19%, versus gains of about 22% for the S&P and roughly 0.2% for the ETF. -Claudia Assis This content was created by MarketWatch, which is operated by Dow Jones & Co.
