Lisbon Airport
In January 2019, Portugal's government unveiled a 1.1-billion-euro ($1.26 billion) plan to expand Lisbon's current airport and build a second one. National airports operator ANA is footing the bill to adapt a military airfield in Montijo, by road from Lisbon. It aims to handle around 50 million passengers a year from 2022. The airports company will also pay for the expansion of the Humberto Delgado Airport in the capital. With around 29 million passengers a year, it is at full capacity.
