Continental Portugal's 89,015 km2 (34,369 sq mi) territory is serviced by four international airports located near the principal cities of Lisbon, Porto, Faro and Beja. Lisbon's geographical position makes it a stopover for many foreign airlines at several airports within the country. The primary flag-carrier is TAP Portugal, although many other domestic airlines provide services within and without the country. The government decided to build a new airport outside Lisbon, in Alcochete, to replace Lisbon Portela Airport, though this plan has been stalled due to the austerity. Currently, the most important airports are in Lisbon, Porto, Faro, Funchal (Madeira), and Ponta Delgada (Azores), managed by the national airport authority group ANA – Aeroportos de Portugal.
