On 6th September, European airlines and the European Union's justice and security commissioner said they opposed any attempt to ban passengers from carrying all forms of liquids on flights.

EU security experts were meeting on 6th and 7th of September to make recommendations after Britain said on 10th August it had foiled a plot to blow up U.S.-bound transatlantic airliners. Officials said the plot involved homemade liquid explosives.

Sources close to the meeting said liquids and gels may be banned from hand luggage on flights.

"Prohibiting all liquids on board we see as unrealistic," said Francoise Humbert, spokeswoman for the Association of European Airlines.

"People need to have something to travel overnight with them. You might need to travel with medication, liquid medication, so this kind of thing should be allowed," she said, adding small quantities should be permitted.

EU Justice and Security Commissioner Franco Frattini backed the airlines' position.

"It's much better in my personal view to focus on detection of liquid explosives rather than generically banning all liquid materials," Frattini told Reuters in a phone interview.

"Our parallel preoccupation is to avoid taking disproportionate measures affecting the daily lives of millions of European citizens. We have to strike the right balance."

Any change to the rules on the transport of goods on flights would be decided by the European Commission as a whole after the security experts made their recommendations, said a Commission official.

Airport screening in mainland Europe is largely the same as it was before August 10, except for U.S.- and British-bound flights on which liquids have been forbidden.

But Britain's announcement of the transatlantic airliner bombing plot has prompted discussion about the need for EU-wide security action.

The airline industry is keen to prevent expensive flight delays and says security costs should be borne by EU countries.

"We're asking for member states to recognise that the threat was against them and that passengers should not pay and that airlines and the air transport industry should not pay," said Humbert.
