BERLIN: A European Union official says she’s trying to get airports to offer cheap water for travellers after they’ve been through security checks. Air travellers in the EU aren’t allowed to take liquids in containers larger than 100 millilitres through security checks. That effectively means passengers wanting to take water on their flight have to buy it in departure lounges, where it’s sometimes considerably more expensive than in normal shops. EU Transport Commissioner Violeta Bulc was quoted on Sunday as telling Germany’s Welt am Sonntag newspaper that talks are taking place.
