Alcochete
On January 10, 2008, Portuguese prime minister José Sócrates announced that Alcochete had been selected as the site of the new airport serving Lisbon, Portugal's capital. The existing Portela Airport, which is located within the city of Lisbon itself, has become too small to handle demand. This preliminary decision will be finalised after public consultation. The location of Alcochete as the construction site of the future Lisbon Airport was confirmed by the Portuguese Government on May 8, 2008.
