03/12/2001 (Agence Europe) - The European Commission called upon Switzerland for further information on aid paid to Swissair and Crossair and on the prices practised by these companies, during an informal EU/Switzerland working group on this subject, last Friday in Brussels. It presented the content of complaints presented by Lufthansa and Ryanair against all Swiss competitors (see p.18). Swiss experts pointed out that they would be providing their analysis of prices practised by Swissair and Crossair as soon as possible. Furthermore, the ministers of the Alpine countries adopted, on Friday, a declaration on traffic security and conditions in the region, at a meeting organised by Switzerland. EUROPE will come back to this.
