It is true the last major Airport in Portugal mainland will receive Ryanair on next November. For now the low cost airline will operate four routes from Lisbon, connecting the Portuguese capital to London, Paris, Frankfurt and Brussels.
Apart of all the problems involving this low cost carrier it is known that there is a great probability if not 100% sure that there will be an increase of passengers to Lisbon and hopefully representing an increase in tourism. However the new route operated by the budget carrier will affect directly the Portuguese Flagship Airline TAP that will now have a strong competition in four of its most profitable routes in Europe. The Portuguese airline is now undergoing a possible privatization process as the last one was canceled after the only interested failed to fulfill all the requirements, and now this new "boy in town" can represent a set back when negotiating TAP's value.
