ual

ual is a three-letter sequence that appears in different contexts. Two of its most prominent uses are as the Nasdaq ticker symbol for United Airlines Holdings, Inc., and as the ICAO airline designator for United Airlines. In finance, UAL refers to the publicly traded parent company of United Airlines, while in aviation it identifies the airline in flight-planning and air-traffic-control systems.

United Airlines Holdings, Inc. is an American airline holding company headquartered in Chicago. It operates as the parent of United Airlines, with a network of domestic and international routes and a fleet serving destinations worldwide. The company traces its corporate name to 2019, when United Continental Holdings adopted the United Airlines Holdings name after reorganizations that followed the earlier United–Continental merger. In common market listings, the stock is listed on the Nasdaq under the symbol UAL and is widely followed by investors and analysts for aviation industry exposure.

The ICAO designator UAL is used in aviation operations to identify United Airlines in flight plans, weather reports, and air-traffic communication. Each airline is assigned a unique three-letter code by the International Civil Aviation Organization, separate from the IATA two-letter code (UA for United Airlines). The callsign used in voice communications is UNITED.

Outside these contexts, ual can appear as an acronym or initialism in various organizations, projects, or products. Because there is no single canonical meaning, the intended interpretation of ual depends on the field and surrounding information.
