Data is Global Top 5 destination cities by international visitors between Q2 2012 to Q2 2013. An international visitor for the purposes of this list is a person who is traveling on a non-stop direct flight to their destination and is not a resident of the destination country. A visitor may make more than one trip, and each trip counts as a new visit. That is, a person who makes two trips to a destination as described above counts as two visitors to that destination. A person on the return leg home does not count as a visitor. Latest available data as of March 2015.Wong. Y, Choog, D. (2013): "MasterCard Worldwide Insights."
