Description: Controls whether the system is allowed to forward Reservation/Journey data to external systems when retrieving availability
<Availability allowReservationData="false" />
Note: Allow Reservation Data from *current session* of the *current PNR/EPR* to be included in availability requests. This option has effect when availability data is refreshed from carrier's inventory system (for example when //Availability[@quality=TRY_TO_REFRESH] ). The Reservation Data, depending on the EPR used to establish the session and what is already booked, may include items such as passenger names, Frequent Flyer numbers (personal and/or corporate), PNR record locators, or segments already booked.
