Bristol Airport , at Lulsgate Bottom, on the northern slopes of the Mendip Hills, in North Somerset, is the commercial airport serving the city of Bristol, England, and the surrounding area. It is southwest of Bristol city centre. Built on the site of a former RAF airfield, it opened in 1957 as Bristol (Lulsgate) Airport, replacing Bristol (Whitchurch) Airport as Bristol's municipal airport. From 1997 to 2010, it was known as Bristol International Airport. In 1997, a majority shareholding in the airport was sold to FirstGroup, and then in 2001 the airport was sold to a joint venture of Macquarie Bank and others. In September 2014, Ontario Teachers' Pension Plan bought out Macquarie to become the sole owner.
