US Airways (Phoenix Sky Harbor) shareholders have approved the proposed merger with American Airlines (AA, Dallas/Fort Worth), CEO Doug Parker has announced. Mr. Parker stated that enough shares were cast in favour of the merger to guarantee approval paving the way for the creation of the world's biggest airline, set to be headed by Mr. Parker and based in Texas. According to the terms of the merger, US Airways shareholders would get 28% of the shares in the combined company, with the rest going to creditors, employees and shareholders of American Airlines parent, AMR Corp. While the deal is still being reviewed by antitrust regulators at the U.S. Department of Justice, critics have voiced concerns over the resulting lack of competition that will emerge as then only four airlines including United Airlines (UA, Chicago O'Hare), Delta Air Lines (DL, Atlanta Hartsfield Jackson) and Southwest Airlines (WN, Dallas Love Field), would control "over 80% of the US market."
