Shannon Airport had been providing U.S. immigration pre-clearance since a successful initial trial in 1986, but customs and agriculture inspections for each flight’s passengers still had to be performed upon their arrival in the U.S. Without full preclearance, Shannon Airport passengers would not be able to easily access domestic connecting flights in the United States.
Based on its extensive experience with US Customs and Border Protection, Dublin Airport Authority plc retained InterVISTAS to deliver a strategy to achieving full Preclearance and assessing the facility, policy and operational capacity required to meet U.S. standards. InterVISTAS further support the airport in defining general aviation preclearance requirements.
U.S. pre-clearance service started in August 2009. Shannon Airport says the attractiveness of the service is already reflected in British Airways’ decision to have a transit stop in Shannon and use pre-clearance at the same time on its new all-business service from London City to New York JFK. Corporate aviation preclearance started in 2010 for private jet travel and is the only one of its type outside the Americas.
