The International Civil Aviation Organisation (ICAO) has said that airline passengers may once again be allowed to board flights with creams, gels and liquids that had been banned over security concerns, AFP has reported. “In the next two years (the ban) will end,” ICAO secretary general Raymond Benjamin told the news service. The lifting of the ban would be due to new equipment capable of detecting explosives in water bottles, makeup kits or toothpaste tubes, being installed at most airport security checkpoints by 2012, he said.
