The first mass carrier at Dortmund Airport was Air Berlin, which began flights to London, Milan, and Vienna in 2002, supplementing its leisure routes to the Mediterranean. easyJet made Dortmund a hub in 2004, and Germanwings followed in 2007. Air Berlin ceased most non-leisure routes from Dortmund in 2005, but easyJet has taken over in this role. However, easyJet cancelled four of five destinations in 2012. To this day the relatively popular London-Luton route is the only one served by easyJet.
