Lisbon Airports & Ground Transportation
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. As the largest airport in Portugal, it offers a wide array of amenities including duty-free shopping, restaurants, and car rental services. The airport is well-connected to the city center via the Metro (Red Line), making the journey quick and affordable. Alternatively, you can catch a ride on the Aerobus or opt for a taxi or ride-sharing service for a more direct route to your destination. Keep an eye out for the traditional Portuguese tile decorations as you make your way through the terminals!

Other airports
While Lisbon Portela Airport (LIS) is the main gateway to the city, consider Faro Airport (FAO) or Porto Airport (OPO) for potentially cheaper flights, especially if you're planning to explore more of Portugal.

Taking a train from either city might be the most relaxing option, letting you enjoy Portugal's beautiful landscapes!
