The main one is in the middle of the country near Lisbon (LIS). This is where many international flights currently land. Lisbon airport is also a hub for European travelers who are heading elsewhere. Other important airports can be found near Porto (OPO) in the north and Faro (FAO) in the south. There is also one on Madeira Island (FNC), which has been built out into the ocean due to the lack of space on the island. It is considered one of the most dangerous in Europe, mostly for that reason.
