the company operates a fleet of 36 aircraft, providing connections to multiple domestic and international destinations. Its network is further extended through a codeshare agreement with Etihad Airways. Flyadeal and SaudiGulf Airlines, among others, are also common low-cost carriers, though these mostly operate domestic flights. In addition to these public airlines, Saudi Aramco operates its own private airline, Saudi Aramco Aviation, with a fleet of 7 aircraft and multiple helicopters, and their own terminals in several cases, which they use for the transportation of employees to and from several far-flung locations such as Shaybah, Yanbu and Tanajib. In 2019, the Saudi Public Investment Fund (PIF) launched the first commercial helicopter that will serve to transport customers within the major Saudi cities and to take them to different tourism destinations. Water transportation Like all states in the Arabian Peninsula, Saudi Arabia does not have any rivers or inland waterways. This has not stopped the kingdom from pursuing the development of a water transportation network, primarily constructed to support the transport of petrochemicals. The Saudi Ports Authority (Mawani) runs and manages the major ports in the country, overseeing their operations. There are some other ports in the kingdom managed by other entities, such as the King Abdullah Port. The largest port on the Persian Gulf, the King Abdulaziz Port, is located in Dammam. Ports Economic impact The development of a road network plays an important role in the economic development of a country and therefore, the mileage of paved roads existing in a country is often used as an index to assess the extent of its development. The proper development of transport road network not only reduces the cost of transportation both in terms of money and time but also helps in the integration of various regions within the country and better understanding of neighbouring countries at the international level. The transport road network in Saudi Arabia contributed to the development of the country by bringing in direct benefits from its role in the development of some sectors such as minerals, agriculture, industry and commerce.
