Final answer:
Passengers are generally advised to consume alcohol in moderation during flights and must be of legal drinking age. The FAA can refuse alcohol service to those who appear intoxicated. Additionally, strict regulations apply in countries where alcohol is culturally or religiously prohibited.
Step-by-step explanation:
Regulations on Alcohol Consumption During Flights
When it comes to passengers consuming alcohol during a flight, the regulations can vary depending on the airline and the laws of the country the airline is based in or flying over. However, there are some general practices and rules that are commonly followed. Firstly, passengers are expected to consume alcohol in moderation, with guidelines often suggesting up to one drink per day for women and up to two drinks per day for men. Additionally, alcohol should only be consumed by adults of the legal drinking age. Importantly, while the historic Eighteenth Amendment and the Volstead Act once prohibited the manufacture, sale, and transportation of intoxicating liquors in the United States, these were later repealed by the Twenty-First Amendment.
In present times, the Federal Aviation Administration (FAA) regulations stipulate that airlines can refuse to serve alcohol to passengers who appear intoxicated or who are likely to become a threat to the safety and comfort of others on board. This is to ensure the safety of all passengers and crew. Some countries, particularly those where alcohol is banned due to religious or cultural reasons, may have stricter regulations on the transport and consumption of alcohol. Passengers flying to or from these countries or over their airspace should be aware of these restrictions to avoid legal consequences.
