London, England (CNN) -- British airlines should stop "kowtowing" to American security demands like making passengers take off their shoes and remove laptops from carry-on bags, the chairman of British Airways argued at an industry conference. Some security checks required by the Americans are "completely redundant," Martin Broughton said at the UK Airport Operators conference in London Monday night, BA confirmed to CNN. He also criticized the United States for demanding tighter security on inbound international flights than they do for U.S. domestic travel. "America does not do internally a lot of the things they demand that we do," he said. "We shouldn't stand for that. We should say, 'We'll only do things which we consider to be essential and that you Americans also consider essential.'
