York is lucky in that it is quite central within the United Kingdom. You may fly into airports in Manchester, London, Newcastle-upon-Tyne and even Edinburgh, and then travel easily by train to York station, near the city centre. 

We cannot improve on the webpage provided by the university's Economics Department for all sorts of information and further details about travelling to York: link to travel information
