newly merged airline was to carry the Olympic brand name and logo, after a transition period in which both airline brands would be used in parallel. The Aegean brand would cease to exist after the transition period. It was expected that the merger would be finalised and the combined airline would begin operation by October 2010. Aegean joined Star Alliance at the end of June 2010. The intent was for the merged carrier to be a Star Alliance member, despite the fact that Olympic Air was forging ties with SkyTeam pre-merger. Star Alliance welcomed the proposed merger, releasing a statement stating "The integration teams from both sides will soon meet to assess the necessary steps, in order to guarantee a smooth transition of the merged Aegean Airlines and Olympic Air operations into the Star Alliance network". On 26 January 2011, the European Commission blocked the merger between the two airlines, citing anti-competition concerns. The commission stated that the merger would have created a "quasi-monopoly" in Greece's air transport market, with the combined airline controlling more than 90% of the Greek domestic air transport market. The EC further stated its belief that the merger would lead to higher fares for four of the six million Greek and European passengers flying to and from Athens each year, with no realistic prospects that a new airline of sufficient size would enter the market to restrain the merged airline's pricing. Additionally, commissioner Joaquin Almunia stated that the merger would have led to higher prices and lower quality of service for Greeks and tourists traveling between Athens and the islands. Both carriers offered remedies in an attempt to ease concerns, though the EU believed that they would not be enough to protect travelers adequately and ease competition concerns. One of the remedies offered by the airlines included ceding takeoff and landing slots at Greek airports, though the commission noted that Greek airports do not suffer from the congestion observed at other European airports in previous airline mergers or alliances. On 21 October 2012 Aegean Airlines announced that it had struck a deal to acquire Olympic Air, pending approval by the European Commission. On 23 April 2013, the European Commission issued a press release announcing it was starting an in-depth investigation into the proposed acquisition of Olympic Air by Aegean Airlines and announcing that the Commission will have decided by 3 September 2013.
