Japan Airlines Enforces Stricter Liver Checks for Pilots Amid Alcohol Issues

Japan Airlines (JAL) is implementing stricter liver function checks for pilots in response to escalating alcohol-related issues. This decision follows increased scrutiny from the Japanese government due to several incidents involving intoxicated pilots.
Stricter Measures for Pilot Alcohol Testing
Reports from Kyodo News indicate that JAL plans to enhance liver testing protocols to identify at-risk pilots. Those whose liver function is below the established thresholds may face suspension from flying duties.
Government Pressure on Japan Airlines
The Japanese transport ministry has called for more stringent measures to address safety concerns arising from pilot alcohol use. This demand comes after multiple incidents led to pilot suspensions and terminations.
Recent Alcohol-Related Incidents
- April 2024: A JAL flight from Dallas to Tokyo was canceled when the captain was reported intoxicated and disruptive, requiring police intervention.
- December 2024: Two pilots exceeded the airline’s alcohol limits, causing a three-hour delay on a flight from Melbourne to Tokyo. Both were subsequently fired.
- August 2025: A JAL captain admitted to drinking before a flight from Honolulu to Nagoya, resulting in delays for three flights, costing their job.
In light of these recurring issues, JAL is reviewing its policies, including a proposed alcohol pledge for pilots, which faced backlash and was ultimately reconsidered.
Developing Testing Framework
Collaborating with various stakeholders, Japan Airlines is now focused on shaping a robust framework for pilot testing. The aim is to enhance safety and restore public confidence in airline operations.
As Japan Airlines reinforces its policies, the spotlight remains on its efforts to mitigate future alcohol-related incidents and ensure passenger safety.
