The Swiss Civil Aviation Authority (Bundesamt für Zivilluftfahrt BAZL) initiated proceedings against 14 airlines which alledgedly have violated passenger rights as provided by Reg. 261/2004. This European Regulation came into force in Switzerland on Dec. 1, 2006. Though the BAZL observed that for the most part the complaints filed by passengers were unfounded, it decided to take a closer look with regard to 14 airlines and has asked them to deliver detailed statements.Source: BAZL press release of May 5, 2011
