Final answer:
OAL (Other Airline) inclusion in display is a term used in the travel industry's reservation systems to show flight options from airlines other than the one being directly queried, such as United Airlines, American Airlines, and others.
Step-by-step explanation:
Understanding Other Airline (OAL) in Display
When working within the travel or airline industry, particularly in the field of reservations or ticketing systems, the term OAL (Other Airline) signifies the inclusion of flights operated by airlines other than the one you are directly accessing or querying.
For example, when using a Global Distribution System (GDS), travel agents often need to display a range of flight options, which may include airlines like United Airlines, American Airlines, Delta Airlines, Alaska Airlines, Pinnacle Airlines, and Airtrain Airlines. These airlines may not be part of the same alliance or partnership, so specifying OAL ensures that flight options from these additional carriers are displayed, providing a comprehensive selection for the customer to choose from.
