Professor do MIT (EUA) questiona sensatez da desactivação da Portela

"Since the plans for the development of the 3 billion Euro new airport for Lisbon emerged in 1990s, the air transport situation has changed dramatically — in Europe in general, and Portugal in particular. Along with trends across the continent, the low-cost airlines have developed strongly, and the mid-size national airlines (such as Olympic, Sabena, Swissair – and including TAP) have struggled financially and required substantial subsidies to stay alive. In short, the low-cost carriers have become important participants in Portuguese air transport, and need to be considered seriously."
