TAP Air Portugal is the national airline of Portugal, operating scheduled passenger and cargo services across Europe, the Americas, Africa, and beyond. Founded in 1945, it has grown into one of the leading transatlantic carriers, leveraging Lisbon's strategic geographic position as a gateway between continents. The airline became a member of the Star Alliance in 2005, expanding its codeshare and interline network significantly. TAP underwent a major fleet modernization program, introducing Airbus A320neo family and A330neo aircraft to improve fuel efficiency and passenger comfort. After financial difficulties, TAP was partially renationalized by the Portuguese government in 2020 and underwent a restructuring plan. The airline has continued to expand its route network, particularly focusing on connections between Europe and Latin America via its Lisbon hub.
