What does the acronym INAD stand for in Ryanair's Special Service Request context?

The acronym INAD stands for "Inadmissible Passenger." This term is used in the context of airline operations, including those at Ryanair, to refer to passengers who cannot be allowed entry into a country due to various reasons such as immigration status, incomplete travel documentation, or other regulatory compliance issues. This designation is critical for airlines because they must ensure that passengers traveling to international destinations meet the entry requirements of their destination country. When a passenger is classified as INAD, special procedures are often required to manage their situation, including potential repatriation or assistance in resolving their immigration status.

In contrast, the other options do not accurately reflect the specific context of airline operations regarding passenger admission into a country, making them less relevant in understanding the role of the SSR process in relation to passenger management.
