company would trade under the Vueling name, Clickair's Alex Cruz was named as chief executive. The deal was subject to scrutiny and approval by European competition regulators, who were concerned that the merged airline would have a significant competitive advantage on around 19 routes. The regulators demanded the release of slots at Barcelona and other European airports as a condition of the merger. On 15 July 2009 the merger of Vueling and Clickair was completed. The new merged airline operates under the Vueling brand, with Clickair flights and aircraft re-branded under the Vueling name.
