One big question for travelers is which Lisbon airport to fly into. Here’s a quick guide to Lisbon’s airports and how to get to the city from each:
Lisbon Airport (LIS)
Lisbon Airport (LIS), also known as Humberto Delgado Airport, is the primary international gateway to Portugal, located just 7 km (4.3 mi) from the Lisbon City center.
