“Turning up drunk”, “too drunk to fly” these are sensationalized statements that perhaps don’t tell the complete story. Being drunk and having residual blood alcohol from the previous nights beer are different. Unfortunately for this crew their BAC exceeded the country’s limit which is 50% more restrictive than the US FAA limit. Granted, some countries limits are zero BAC which is 100% more restrictive the the USA limit of .04, so the safest course of action for airline pilots on a layover is don’t drink at all because the consequences may be life changing.
