These are the various ways to get from the airport to the center of Lisbon:
Aerobús. The aerobús is a shuttle service that links Lisbon airport to the city center. It consists of two routes, one runs through the city center (final stop: Cais do Sodré) and the other runs through the city’s financial district (final stop: Av. José Malhoa). The bus that connects the Airport to the center, departs every 20 minutes from 8 am – 11 pm. A one-way ticket costs 4 EUR (2 EUR for children between 4 and 10) and 5.40 EUR return (3 EUR for children). After validation on the bus, the ticket can be used for 24 hours. Tickets can be bought, often with discount, on the Aerobus website.
Metro. Fast and inexpensive. The Metro’s recent enlargement links the Airport with the heart of Lisbon. A single ticket costs 1.45 EUR. You would need to buy the Viva Viagem or 7 Colinas card, and recharge it with the value you want. Note that during rush hours, you might have to wait up to 15 minutes to buy a ticket.
Local buses. The transport company Carris offers 5 bus routes between Lisbon airport and the centre. A one-way ticket costs 1.85 EUR. With a Viva Viagem or 7 Colinas card loaded, the ticket is cheaper, and costs 1.45 EUR.
Taxi. A taxi is a comfortable and relatively cheap way of getting from the airport to your hotel. It normally costs around 20 EUR to get to the city centre. You can purchase a pre-paid ticket in the taxi rank, that way you will know the price before getting in the taxi and avoid possible surprises. Keep in mind that the waiting time for an available taxi can be very long since the airport of Lisbon is usually very busy.
Airport Transfer Service. This is the most expensive option, but also the most comfortable and hassle-free. A chauffeur will pick you up from your terminal with a sign with your name on it. You can book this option directly on the internet.
