A growing number of "air rage" incidents is forcing the UK government to consider a ban on drinking alcohol on all domestic and international flights on British airlines.

A report in the London Sunday Times newspaper says the measure is being debated as part of preparations for a government study paper on aviation, due for publication in the spring.

The UK's airline safety authority, the CAA, has reported a big increase in the number of violent or threatening incidents on aircraft - up from 800 three years ago to 1,250 in 2001.

This steady increase in attacks by drunk passengers on cabin crew members has forced the issue on to the government's agenda. Should the proposals become concrete they will be opposed by airlines but already have the backing of cabin crew and groups representing the traveling public.

Doctors have added their weight to the argument, saying that alcohol on flights should be banned.

The newspaper says that the government put out a consultation document and many of those who replied urged a complete ban on in-flight drinking.

The Sunday Times cites Transport Department insiders as saying that the most likely scenario is a bar on airlines from which cabin crew would be able to control the number of drinks handed out. They do not see a complete ban on alcohol as being the answer.
