Situated around 6km north of the centre, the ultramodern Aeroporto de Lisboa operates direct flights to major international hubs including London, New York, Paris and Frankfurt. Low-cost carriers (EasyJet, Norwegian, Ryanair, Transavia, Blue Air and Wizz Air) leave from the less efficient Terminal 2 – you'll need to factor in extra time for the shuttle ride if arriving at the airport on the metro.
The AeroBus departs from outside the Arrivals Hall. Line 1 (from 7.30am to 11pm) goes via Martim Moniz, Praça do Comércio, Cais do Sodré, Rossio, Restauradores, Av da Liberdade, Marquês de Pombal and Saldanha. Line 2 (from 7.40am to 10.45pm) goes via Saldanha, Marquês de Pombal and Sete Rios (for bus terminal access). You'll save 10% by purchasing your tickets online in advance.
The Aeroporto metro station allows convenient access to downtown. Change at Alameda (green line) to reach Rossio and Baixa.
Expect to pay about €16 for the 15-minute taxi ride into central Lisbon, plus €1.60 if your luggage needs to be placed in the boot. Avoid long queues by flagging down a taxi outside the Departures Hall. Make sure the cabbie switches on the taxi meter, that you hold them to the route (follow along with Google maps, if possible) and that you pay the listed fare – taxis in Lisbon are notorious for fleecing tourists, especially from the airport.
Uber and other ride-share services pick up passengers outside the Departures entrance at Terminal 1 (not Arrivals) – and eliminate the potential rip-off factor.
