Why fly to Lisbon?

Lisbon has become one of Europe's fastest-rising destinations for American travelers, and value-seekers are leading the charge: Portugal's capital pairs sun-washed hills, pastel tiled facades, and clattering yellow trams with prices that still undercut Paris, Rome, or Barcelona. The city tumbles down toward the Tagus River in a maze of viewpoints, or miradouros, where you can nurse a glass of vinho verde at sunset for the cost of a coffee back home. U.S. flyers reach Lisbon (LIS) nonstop on TAP Air Portugal, United, Delta, and American from hubs like Newark, New York, Boston, Washington, and Miami, and TAP's well-known free stopover program lets you tack on a few days in Lisbon en route to elsewhere in Europe at no extra airfare. Spend your days getting lost in the Alfama's stair-stepped lanes, riding Tram 28, and eating pasteis de nata still warm from the oven, then take the short train to the fairytale palaces of Sintra. The savings tip that adds up quickly: grab a rechargeable Viva Viagem card for the trams, metro, and ferries, since the per-ride fare on the card is a fraction of what you'll pay buying tickets onboard from the driver.

Best months to fly to Lisbon

FAQs: cheap flights to Lisbon

When are flights to Lisbon the cheapest from the U.S.?
Winter, particularly January and February, offers the lowest transatlantic fares to Lisbon, with November close behind. The summer peak from June through September is the priciest and busiest season, so the spring and fall shoulder months reward travelers with mild weather and fares well below the summer high.
Which U.S. cities have nonstop flights to Lisbon?
Newark, New York, Boston, Washington, Miami, San Francisco, and Chicago offer nonstops to Lisbon, with TAP Air Portugal flying the most routes. Because Lisbon is a growing value destination served by both legacy and flag carriers, comparing airlines across flexible dates is the best way to lock in a low fare.
Can I do a free stopover in Lisbon on the way to another European city?
Yes. TAP Air Portugal's stopover program lets you spend up to a few nights in Lisbon or Porto at no additional airfare when connecting to another destination on its network. It's a popular way for Americans to add a Portugal visit to a larger Europe trip for free.
Do I need a passport or visa to visit Lisbon?
U.S. citizens need a valid passport but no visa for stays up to 90 days in Portugal. Be sure your passport has at least three months of validity past your departure date. The EU's planned ETIAS travel authorization may soon require a quick online approval before you fly, so check ahead.
What is the cheapest way to get from Lisbon airport into the city?
The Metro's red line runs directly from Lisbon Airport into the city center for a couple of euros, far cheaper than a taxi or rideshare. Loading a reusable Viva Viagem card brings the per-ride cost down further and works across the metro, trams, buses, and ferries throughout your stay.
