Swiss secures IATA safety audit

Swiss International Air Lines and its independent wholly-owned subsidiary Swiss European Air Lines successfully passed the IATA Operational Safety Audit (IOSA) last week. This was the first time anywhere in the world that two airline operations - Swiss International and Swiss European - have been audited at the same time. The registration will remain valid for two years.

The purpose of the IOSA is to achieve an internationally-recognised high standard in the fields of flight operations and safety. “We are particularly pleased to secure this IOSA registration in that these audits were completed without a single ‘finding’ requiring action on our part, either at Swiss International or at Swiss European,” says Manfred Brennwald, SWISS Chief Operating Officer. “We view this as a confirmation of the kind of high quality standards that passengers should be able to expect from a quality airline.”

IOSAs are repeated every two years. Last week’s audit was conducted simultaneously for both Swiss International and Swiss European - the first time this has been done in IOSA history. Both audits were conducted by an independent audit organisation in the presence of representatives from the International Air Transport Association (IATA).

What does IOSA mean? - The IATA Operational Safety Audit (IOSA) is an internationally-recognised and accepted auditing system for evaluating an airline’s operating procedures and management systems.

The IOSA is based on proven quality management principles, and has been designed to enhance operating procedures and above all to standardise such audits, permitting their worldwide comparison and the common use of audit reports. This substantially reduces the total number of audits required, and this in turn permits sizeable cost savings for participating airlines.
