Glasgow Airport achieved the maximum five stars following a four-day assessment.
The audit was based on interviews with staff, site tours, inspections and a review of the airport’s safety management.
Alex Botha, chief executive of the British Safety Council, said: “Managing one of the UK’s major airports, and all the risks that entails, is immensely challenging.
“Everyone concerned should derive tremendous satisfaction from their achievement.
“The auditors identified many strengths in Glasgow Airport’s management of risk in its operation, including the role played by senior management in providing leadership and direction and the role of the wider workforce in ensuring the airport is kept safe and secure.”
Gillies Crichton, Glasgow Airport’s head of assurance, said: “The safety of our passengers and staff is our number one priority at all times and to be the first UK airport to achieve five stars in this audit is a fantastic achievement, particularly at the first attempt.
“It reflects the hard work which has taken place across the campus to reach this level.”
