Nas Air, officially known as National Air Services, is a Saudi Arabian low-cost carrier established in the mid-2000s. Operating under the IATA code XY and ICAO code KNE with the callsign NAS EXPRESS, the airline was one of the first budget carriers to emerge in the Saudi Arabian aviation market. The airline primarily served domestic routes within Saudi Arabia as well as select regional international destinations across the Middle East and North Africa. Nas Air aimed to make air travel more affordable and accessible to passengers in the region. Nas Air faced significant financial and operational challenges over the years, leading to a suspension of operations. The airline struggled to maintain consistent service amid competitive pressures and regulatory issues in the Saudi aviation sector.
