US airline trade association, Airlines for America (A4A) has expressed concerns over the US administration's 'misguided' agreement with the UAE to establish a US Customs and Border Protection (CBP) preclearance facility at Abu Dhabi International Airport. "Granting the UAE a preclearance facility makes it much easier to enter our country if you fly through Abu Dhabi than it is to fly directly into JFK, Houston, Miami, Chicago or Dallas," said A4A president and CEO, Nicholas E Calio, as he testified before the House Foreign Affairs Committee. "This agreement significantly tilts the competitive playing field against US airlines," he added. Calio also voiced his strong opposition to US taxpayer dollars being used to foot the bill for preclearance services in Abu Dhabi, particularly while passengers wait in lines up to four hours to clear customs at US gateways. "This diversion of taxpayer dollars to assist wealthy foreign airlines cannot be justified," said Calio.
