What does the acronym INAD stand for, indicating a passenger's status?

The acronym INAD stands for Inadmissible Passenger. This designation is used in the aviation industry to refer to a situation where a passenger cannot be allowed entry into a country or region upon arrival. This status is typically due to various reasons such as lacking necessary travel documents, not meeting visa requirements, or being considered a security risk.

When an individual is classified as an INAD, specific procedures must be followed by airlines and immigration authorities to manage the situation, including potentially returning the passenger to their point of departure. Understanding this term is crucial for airport and airline operations to ensure compliance with international travel regulations and security protocols. The other options, while related to passenger statuses, do not specifically capture the meaning of INAD.
