Other airlines may impose restrictions on drinking at certain times of day, such as the morning.

This will depend on the destinations that you're flying between. For example, the UK legal drinking age is 18 and the US legal drinking age is 21 (in most states) — if an 18-year-old passenger were to fly with alcohol from the UK to the US, it would be legal for the time that they're in the UK. However, when they land in the US, it would be illegal for them to have alcohol in their possession.

There is no hard rule for this and it will differ depending on the airline. However, most airlines will apply the legal drinking age of the country from which it is based. For example, a British Airways flight travelling from New York to London will allow anyone aged 18 or over to drink alcohol on the flight. This will apply as soon as it takes off from New York, as while it's still on US land, the legal drinking age of the state of New York will apply (aged 21).

On the other hand, if a US carrier — such as United Airlines — was flying the same New York to London route, passengers would have be 21 years or older to drink on the flight.

The temperatures inside a plane's hold are subject to dramatic change which has the potential to damage wine.
