The situation of flight attendants or drinkers surprised public opinion, because air transport is an industry that requires a very high level of safety. In fact, almost every airline has strict rules banning alcohol and substance use. The Federal Aviation Administration (FAA) states that flight attendants must not drink alcohol 8 hours before their duty and the amount of blood alcohol must not be higher than 0.04 (half the limit of drivers on the road).
Many airlines have stricter regulations, including blood alcohol content that does not exceed the 0.001 threshold or ban drinking alcohol 12 hours prior to duty. Companies like ANA also require flight attendants not to drink alcohol 24 hours before work.
However, regulatory enforcement is a different story. JetBlue claims it does not tolerate crew members failing to pass the alcohol and drug test. However, those who actively seek treatment for alcohol or drug dependence will receive free treatment. American Airlines allows crew members to be found using alcohol and drugs while working on a multi-month detox program approved by FAA.
