The lack of a uniform landscape looks set to prolong existing confusion about the rules when it comes to clearing security at UK airports; most airports still impose a 100ml liquid limit, with some allowing liquids and electronic items to remain in bags and others not.
Edinburgh airport this week became the first Scottish airport to lift the long-standing 100ml rule, and now operates a two-litre restriction on liquids. Birmingham has also upped its limit to two litres.
