Anyone who has ordered drinks on a flight has probably noticed this at some point. The first drink arrives easily, maybe even the second, but after that, cabin crew suddenly become a lot more careful. Sometimes they politely refuse. Sometimes the service slows down completely.
Many passengers assume airlines simply want to save money by limiting alcohol in economy class. But in India, the rules around in-flight drinking are tied far more closely to aviation safety than cost-cutting.
According to India’s aviation regulator, the Directorate General of Civil Aviation, alcohol-related unruly behavior has become a serious safety concern on board flights. And contrary to popular belief, these restrictions do not apply only to economy passengers. Even travellers in business or first class can legally be denied alcohol if crew members believe they are intoxicated.

Also, one of the biggest reasons airlines monitor drinking carefully is because flying changes how the body reacts to alcohol.
Aircraft cabins operate at high altitudes with lower humidity levels and reduced oxygen pressure compared to normal ground conditions. This can increase dehydration and make fatigue kick in faster, especially on long-haul flights. As a result, passengers often feel the effects of alcohol sooner than they expect.
This becomes risky inside an aircraft, where medical help, conflict management, and emergency handling are much more limited than on the ground.
Several Indian airlines therefore, train cabin crew to monitor passenger behaviour closely during alcohol service.
The DGCA’s Civil Aviation Requirements (CAR) clearly mention that passengers under the influence of alcohol who behave in an unruly manner can face serious consequences. The regulator states that “consumption of, or being under the influence of, alcoholic beverages” resulting in disruptive behaviour is considered a punishable offence onboard aircraft.
The rules also empower airlines and cabin crew to take action if a passenger’s behaviour threatens safety, crew operations, or other travellers on board.
In recent years, India has seen multiple high-profile in-flight incidents linked to intoxicated passengers, prompting the DGCA to repeatedly remind airlines to enforce stricter monitoring.
The regulator has even proposed tougher penalties and faster no-fly bans for disruptive passengers involved in alcohol-related incidents.
Economy class usually carries the highest number of passengers onboard, which naturally increases the chances of conflicts, noise complaints, or alcohol-related disturbances. Cabin crew also have less time per passenger in economy compared to premium cabins.

That is why many airlines quietly follow internal service policies in economy, especially during late-night flights or routes where alcohol-related incidents are more common.
In 2024, the DGCA clarified before the Supreme Court that airlines themselves have the discretion to decide how much alcohol should be served onboard in order to prevent passengers from becoming inebriated.
So while there is no fixed nationwide “two-drink rule” in India, airlines are allowed to stop serving passengers whenever cabin crew feel it is necessary.
Yes. Passengers travelling in business or first class may get access to premium liquor, wine pairings, and more personalised service, but the same aviation safety rules still apply.
If a passenger appears visibly intoxicated, crew members can legally stop alcohol service regardless of ticket class.
The main difference is that premium cabins usually:
That naturally reduces the risk of someone drinking excessively in a short period. But a business-class seat does not exempt anyone from airline safety rules.

Alcohol-related incidents onboard aircraft are expensive and dangerous for airlines. An unruly passenger can delay flights, disrupt crew duties, create panic among travellers, and in extreme cases force emergency landings or diversions.
The DGCA has repeatedly stated that unruly behaviour can “compromise safety of aircraft operations.” In response, Indian aviation authorities have pushed airlines to adopt a stronger “zero tolerance” approach towards disruptive passengers.
Crew members today are trained not just to serve food and drinks, but also to identify signs of intoxication before situations escalate.Because once an aircraft is airborne, even a small conflict can become a much bigger problem. And that is ultimately why airlines monitor alcohol service so closely, whether you are seated in economy, business, or first class.
