The Neutral Unit of Construction or Neutral Unit of Currency (code: NUC) is a private currency used by the airline industry,[1] to record fare calculation information.[2] A set of exchange rates are issued by the International Air Transport Association (IATA) four times per year.[3] The ticket component prices are converted from the original currency (of the country of commencement of travel) and recorded on the airline ticket.[4]
The NUC system came into being on 1 July 1989, having superseded the older "Fare Construction Unit" (FCU) system.[4] As of 2008, the NUC is pegged approximately to the United States dollar ($1 ≈ 1 NUC).[5]
A similar unit, formerly used by the European railway industry is the UIC Franc (XFU).
