Britain Expected to Loosen Air Travel Rules
Britain will probably announce an easing of air travel rules next week after security was tightened last month in the wake of what police said was a foiled plot to bomb airliners."We intend to announce new regulations next week," a spokesman for the UK Department for Transport (DfT) said on Wednesday. A ban on liquids and gels in carryon luggage and smaller limits on the size of carry-on bags was imposed last month."We always said we would keep those (steps) under review.", a spokesman said. A meeting of government and airline industry officials is set for Monday, and the revised rules will probably be announced later in the week. The owner of London's Heathrow, Gatwick and Stansted airports, said they expected the restrictions to be eased within 24 hours of Monday's meeting.
More than 2,000 flights were canceled in Britain last month after the government ordered tighter checks on passengers and luggage. The United States upped its aviation security alert and also imposed restrictions on bottled drinks, lotions and other liquids in carry-on luggage. There are no indications that US rules will be eased
