As these distribution channels might influence the consumer choice, a 1989 Regulation (No 2299/89), last amended in 1999, ensures that air services by all airlines are displayed in a non-discriminatory way on the travel agencies' computer screens.
The Code of Conduct for CRS was designed in 1989 along with Regulation 2299/89.
Since then, CRS technology and economics have changed a lot: thanks to the development of alternative distribution channels, such as the airlines' Internet websites or their call centres, consumers have nowadays access to a multiplicity of information and booking channels for air transport services. About 40% of all airline tickets in the EU are booked via alternative channels and about 60% via travel agents and CRSs.
To take account of the different market context, the Euopean Commission proposed a revision of the Code of Conduct for computerised reservation systems.
