Humberto Delgado Airport is located within the city limits. It is the headquarters and hub for TAP Portugal as well as a hub for Easyjet, Azores Airlines, Ryanair, EuroAtlantic Airways, White Airways, and Hi Fly. A second airport has been proposed, but the project has been put on hold because of the Portuguese and European economic crisis, and also because of the long discussion on whether a new airport is needed. However, the last proposal is a military airbase in Montijo that would be replaced by a civil airport. So, Lisbon would have two airports, the current airport in the north and a new one in the south of the city.
