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. Since 2006 it has been carrying the name "Dortmund Airport 21", in reference to the fact that Dortmund's utility company, DSW21, is its major shareholder. The airport's master plan consists of the following elements: Increasing normal operating hours by one hour at night (to 23:00h), with an additional one-hour window in the morning and at night for exceptions, lengthening the runway to , expanding the terminal and its infrastructure, improving the motorway connections and directly connecting the airport to mass transit. In October 2014, Air Berlin announced it was leaving Dortmund Airport entirely, cancelling their last remaining summer seasonal route to Palma de Mallorca. The airline had shut down several leisure routes from the airport in 2012. As with easyJet in the 2000s, other low-cost carriers started opening routes from Dortmund Airport. Ryanair has progressively added new routes from Dortmund, mostly to destinations around the Mediterranean and the UK. At one point, Spanish low-cost airline Vueling offered flights to Barcelona, but they have been discontinued despite strong demand. However, Wizz Air has been the most significant contributor to the airport's resurgence. The Hungarian low-cost airline began servicing the airport in the mid 2000s by operating several routes to Eastern Europe, in large parts due to the Ruhr's significant Slavic community. In June 2020, in the midst of the COVID-19 pandemic, Wizzair announced that Dortmund Airport would become its 33rd base, the first in Germany. However, a year later, Wizz Air announced the closure of their Dortmund base which led to the termination of few routes.
