Air India suspends co-pilot over alcohol test as zero-tolerance policy comes into focus.

An Air India co-pilot has been suspended after reportedly failing a pre-flight alcohol test ahead of a Zurich-to-Delhi service on September 6, according to media reports.
The first officer was removed from duty shortly before the flight departed after concerns were raised over possible alcohol consumption. Reports indicate that he failed an initial screening, while the results of a second test carried out in Zurich are still pending.
The co-pilot was subsequently flown back to India as a passenger and remains suspended from duty while authorities await the final medical examination report.
Air India reiterates zero-tolerance policy
Air India said it follows a strict zero-tolerance approach to breaches of safety standards, regulatory requirements and internal company procedures.
The airline added that any confirmed violation is handled firmly, with appropriate action taken in line with applicable regulations and company policies.
The airline said flight crew have been reminded of their responsibility to uphold the highest standards of safety, professionalism and integrity at all times.
Air India added that it regularly conducts awareness and compliance training, requires testing for psychoactive substances and may impose disciplinary action that exceeds minimum regulatory requirements where appropriate.
Pilot previously tested positive for drugs
The latest incident follows another case involving an Air India pilot who reportedly tested positive for marijuana after operating a Phuket-to-Delhi flight, according to The Economic Times.
The pilot in command of flight AI-2379, which was carrying 137 passengers and eight crew members, reportedly returned two positive marijuana test results following an August 4 incident in which the aircraft suddenly lost around 300 feet of altitude while flying over Odisha.
More than 20 passengers and four crew members were reported injured in the incident. The Airbus A320neo subsequently landed safely in Delhi.
The pilot was later dismissed from his position. In a flight safety statement quoted by NDTV, he said he had been experiencing difficulty sleeping due to personal circumstances and had been prescribed medication by his family doctor.
He also said that during the layover he had attempted to rest but struggled to sleep, prompting him to engage in light activity, including walking, in the belief that it might help.
Air India introduces mandatory testing
Following the incident, Air India ordered a new round of mandatory drug testing for all its pilots as part of efforts to reinforce safety and regulatory compliance.
The airline said it has also implemented additional measures, including compulsory screening for psychoactive substances, expanded awareness programmes and stricter adherence to reporting obligations and regulatory requirements.
Air India added that it will continue to monitor compliance patterns and the operational conduct of its employees to ensure safety and professional standards are maintained.
