Looking at the problem from the wrong end?

Holiday flights are horrid enough, but there are plans to make them more horrid.  The I-news reports:

The Home Office is planning to close a loophole that allows airports to sidestep alcohol licensing laws and open 24 hours a day.

The move comes after the International Air Transport Association (IATA) reported a 50 percent rise in in the numbers of passengers forcibly detained for bad behaviour.

A review by the House of Lords has recommended an end to 24-hour drinking in airports, according to The Times.

The Home Office is planning to extend the Licensing Act 2003 to cover alcohol being sold to passengers just before they board flights.

It would give councils the power to license and inspect bars, pubs and restaurants inside airports.

If the problem is drunkenness on aeroplanes, why do the airlines continue to sell alcohol on board?  As far as I am aware, there is no law which requires them to do so.

Besides, a stiff g&t before departure makes the whole process of flying marginally more tolerable.
