Middle East Airlines (MEA) is a member of the SkyTeam airline alliance, the Arab Air Carriers Organization (AACO), and the International Air Transport Association (IATA). The airline expressed its interest in becoming a SkyTeam associate member in early 2006 at a press conference in New York. On 28 February 2011, MEA officially signed the partnership agreement with SkyTeam in an official ceremony in Beirut. On 28 June 2012, MEA officially joined SkyTeam to become its 17th member, as well as its second member airline in the Middle East. MEA restarted by acquiring a Convair 990A from American Airlines, which entered service on 24 June 1969. A Boeing 747-200B entered service in June 1975 on the Beirut – London route, and later on the Beirut-Paris-New York route from April 1983 until mid-1985. MEA had to adjust its operations to the realities of war in Lebanon between 1975 and 1991 and despite multiple closures of the base at Beirut International Airport, was able to continue operating against all odds. Airbus A310-300s were acquired in 1993 and 1994, followed by an A321-200 in 1997 and the A330-200 (which replaced the A310s) in 2001. From 1998 to 2002, MEA implemented its largest restructuring program ever which helped to turn it around from a loss-making airline to a profitable one by 2003.
