What does DUTY® refer to in Ryanair’s special services?

The answer identifying DUTY® as travel for duty purposes is correct because it aligns with the specific categorization of travel requirements that Ryanair recognizes. In the context of special service requests, the term "DUTY®" is intended to indicate travel related to business or official duties, which requires certain considerations and may involve additional arrangements by the airline. This classification allows Ryanair to manage and accommodate the needs of passengers who are traveling for specific professional obligations, providing them with services that may differ from those offered to leisure travelers.

In contrast, the other options pertain to different scenarios. A request for additional baggage specifically involves the logistics of transporting personal items rather than business-related travel. An extra seating requirement usually relates to passenger comfort or medical needs, and a family fare request involves special pricing structures for families traveling together. Each of these requests addresses distinct aspects of passenger needs that are separate from the professional context captured by "DUTY®."
