Lisbon Airport (LIS), the principal facility serving the Portuguese capital, has slowly become one of the most important gateways between North America and Europe. Geography does a lot of heavy lifting, with the facility sitting on the western edge of the European continent. This allows Portugal to offer some of the shortest US-Europe flying times. These shave hours off itineraries that would otherwise require routing through more inconveniently located hubs like London, Paris, or Frankfurt. Once we add in the Portuguese tourism boom, relatively affordable prices, and year-round mild weather, the airport has quickly become a key player in the transatlantic market, which has only continued to expand in capacity.
During the first half of 2025, airlines were set to operate 90% more flights between the United States and Portugal than they did in 2019, significantly outpacing growth in many other European markets. At the center of all this surging growth is TAP Air Portugal, the nation’s flag carrier and the principal operator at Lisbon Airport. TAP has added new routes like Lisbon to Los Angeles, and Porto to Boston, with many of these once-seasonal routes now extended to year-round operations thanks to strong continued demand from both leisure travelers and those visiting friends and relatives (VFR). TAP’s leadership team has been quick to highlight the role it believes that it plays in supporting connecting travel through Lisbon, with the airline’s Portugal Stopover program further cementing the airport’s role as a major bridge between continents.
A Brief Overview Of Lisbon Airport
Lisbon’s Humberto Delgado Airport sits just 4.3 miles (7 km) from the city center, making it one of Europe’s closest major airports to a city’s downtown (with Nice Airport (NCE) being another good example). This proximity is ultimately critical for US travelers on tight schedules, as they can be in a hotel or business meeting within just 20 to 30 minutes of landing or back at the airport quickly for onward connections. The airport is connected by the red line of the Lisbon Metro, numerous city buses, and short taxi or rideshare journeys, making transfers relatively straightforward, even for short layovers.
Operationally, Lisbon Airport is a paradox. The airport is both constrained and yet highly efficient. It is Europe’s 12th-busiest airport by passengers, handling more than 35 million travelers in 2024. Nonetheless, it also operates as a single-runway hub, making it one of the busiest single-runway airports anywhere in the world. This constraint forces a tightly choreographed wave structure of aircraft arrivals and departures, which in turn creates competitive minimum connection times and dense banks of inbound and outbound flights. The airport has two terminals, with Terminal 1 being the main building that handles all global arrivals and most scheduled flights, including TAP’s long-haul network and other full-service airlines. Here are some statistics for Lisbon Airport, according to data released from the airport management agency ANA:
Terminal 2 is smaller and dedicated mostly to low-cost carriers like Ryanair, easyJet, and others, linked to Terminal 1 through a frequent shuttle. TAP holds roughly 46% of seat capacity at Lisbon Airport, while Ryanair and easyJet together account for more than 20% of traffic. This creates a unique blend of full-service and low-cost connectivity, offering plenty of options for passengers looking to travel to destinations across North America and Europe. Lisbon is also a major European gateway to Lusophone Africa and Brazil, meaning travelers can also connect to niche long-haul markets that otherwise might require circuitous routings through other hubs.
TAP Air Portugal: The Airline Behind Lisbon’s Growth
TAP Air Portugal is at the center of Lisbon’s rise to prominence as a transatlantic hub. The airline is the nation’s flag carrier and the dominant tenant at Lisbon Airport. It is responsible for more than half of the nation’s long-haul capacity, and it serves more than 88 destinations from Lisbon alone. The airline’s network is laser-focused on North America, Brazil, and Lusophone Africa, with European routes providing short-haul capacity.
From a financial perspective, the Americas have been behind a large amount of TAP’s growth. In 2024, the airline carried more than 16 million passengers, with North American routes seeing 9% year-on-year growth. TAP has responded by adding new US gateways, including Los Angeles, while launching flights from Porto to Boston. The airline aims to tap into regional diaspora demand and diversify its route network beyond just Lisbon. In a statement to Simple Flying during the World Travel Market, TAP Air Portugal Director of Sales, Frederic Gossot, had the following words to share regarding the airline’s principal hub:
