Lisbon airport is served by numerous low cost and regular companies. If you come from other destinations in Portugal you may use the bus service operated by the company Rede Expressos and Renex .
The national Portuguese flight company TAP (www.tap.pt) offers daily connection to most European cities.
Lisbon airport, Portela, is situated 7 km from the city centre and is connected to Lisbon by the bus line of Carris company, operating from 5:30 am to 24 pm, with rides every 15 minutes. The journey takes approximately 45 minutes and a one way ticket costs Euro 1,40 (it can purchased on board or at ticket offices, but the price is the same). The bus stop is just opposite the airport terminal. Carris also provides a shuttle service (Aerobus) which connects the airport with Praça do Comércio and Cais do Sodré, calling at the main hotels of the city. In addition to the shuttle, an Aeroshuttle is also available, with destination Parque das Naçoes and the terminal station of Sete Rios. The Aerobus going to Lisbon operates from 7.30 am to 23.00 pm, whereas the service from Cais do Sodré to the airport is active from 7.45 am to 22.30 pm, with rides every 20 minutes.
The Aeroshuttle service starts at 7:00 am until 23:00 pm, with rides every 30 minutes.
A single ticket on the Aerobus and Aeroshuttle has a cost of Euro 3,20, a little more expensive than a regular bus, but it represents a good choice if you arrive in Lisbon at rush hours, and it also entitles to travel on the entire Carris network until midnight (with the exception of the underground).
Be careful when you take a taxi: even though the majority of taxi drivers are honest, there are always those who try to apply a higher fare, so check always the tariff in the taximeter, which must be an urban tariff, and ask the driver to keep the taximeter on if he tries to turn it off.

All route to Portugal pass by France (Marseille) and Spain (Barcelona, Madrid). Train is not the cheapest way to reach Portugal, therefore this solution is recommended only if you are particular fond of this mean of transport.
