This article discusses recent evolutions in the regulation of computer reservation systems (CRSs) in the European Union and the United States. Mid November 2007, the European Commission issued a proposal for a revision of the existing regulation of CRS, which dates back to 1989. The article explains the rationale for regulation and subsequent deregulation both in the US and the EU. Whereas the US have chosen to deregulate the matter, the proposal for revision under discussion here maintains many of the existing rules. The article gives an overview of the proposed changes and provides for a critical assessment of the proposal as it stands today.
