Summary TAP Air Portugal's top 5 narrowbody routes are long-haul transatlantic flights to Brazil, Washington DC, and Toronto. These long-range flights use Airbus A321LRs with increased range capabilities. The route from Belém to Lisbon is TAP's longest narrowbody route at 3,726 miles with 20 monthly flights and no competitors.

TAP Air Portugal, the nation's largest airline, operates an extensive route network across Europe, North America, and South America. The airline has a fleet of 21 Airbus A330 widebody aircraft, but it also utilizes its narrowbody planes for medium—to long-haul routes. According to the aviation analytics company Cirium , the carrier's top five longest narrowbody aircraft routes are all transatlantic and operated from TAP's primary base at Lisbon International Airport (LIS), Portugal.

Notably, most of these routes are to Brazilian destinations, with the other two serving Washington DC and Toronto. This comes as no surprise as the Brazilian market makes up a substantial portion of TAP's network. In addition, all of these long-range routes are operated by the airline's Airbus A321LR aircraft, which has 13 units, as per ch-aviation data.

According to Airbus , the A321LR has an increased Maximum Take-Off Weight (MTOW) of 97 000 kg and two or three underfloor fuel tanks, allowing airlines to increase its range up to 4,000 nautical miles (7,408 km) for long-range flights. The issue led to a $5.4 billion charge to RTX, parent company of Pratt & Whitney.
