Amman is introducing itself as a business hub. The city's skyline is being continuously transformed through the emergence of new projects. A significant portion of business flowed into Amman following the 2003 Iraq War. Jordan's main airport, Queen Alia International Airport, is located south of Amman and is the hub for the country's national carrier Royal Jordanian, a major airline in the region. The airline is headquartered in Zahran district. Rubicon Group Holding and Maktoob, two major regional information technology companies, are based in Amman, along with major international corporations such as Hikma Pharmaceuticals, one of the Middle East's largest pharmaceutical companies, and Aramex, the Middle East's largest logistics and transportation company.
