The interests of airlines based in the Middle East are addressed by an organization known as AACO, Arab Air Carriers Association. Among regional carrier groups, AACO is unusual; only two of the group's airlines are affiliated with one of the three global Alliances; Star claims Egyptair and Royal Jordanian is in oneworld. Furthermore, the number of passengers attributable to those two carriers in 2009 is roughly 9.5 million, meaning that less than 10% of the region’s passengers travel on alliance affiliated carriers. And there appears to be only limited scope for this situation to change in the near future, as this overview reports.
