GENEVA: The Swiss Travel Federation filed a complaint on Friday against German airline Lufthansa for breaching anti-cartel laws, the Swiss competition authority confirmed. The organisation, which represents Swiss travel agencies and tour operators, said that a new tax introduced by Lufthansa earlier this month violates Switzerland’s anti-cartel legislation, the Swiss Competition Commission told AFP, confirming a report by the ATS news agency. The problem, according to the report, is that the 16-Swiss-franc ($16.30/14.60-euro) tax is not imposed on reservations made directly with Lufthansa, leaving travel agents and their clients at a disadvantage.
