Sign in to your Simple Flying account TAP Air Portugal is planning a significant change to its Porto–Luanda service, deploying the Airbus A321LR on the 3,737-mile (6,014 km) route from October 31, 2027. The move will create the airline's longest scheduled nonstop A321LR flight, narrowly surpassing its existing Lisbon–Belém service. The decision is particularly noteworthy because TAP intends to replace its 298-seat Airbus A330-900 with a 171-seat narrowbody, reducing passenger capacity by approximately 43%. The long sector also raises questions about baggage and payload limitations, particularly given the substantial baggage requirements that can characterize routes between Europe and sub-Saharan Africa. The change remains provisional, with almost a year until its planned introduction. TAP Plans 3,737-Mile Airbus A321LR Flights To Angola Credit: Wangkun Jia | Shutterstock According to AeroRoutes, TAP's preliminary winter 2027/28 schedule replaces the A330-900 with the A321LR on its twice-weekly service from Porto to Luanda. The route connects northern Portugal with Angola's new Dr. António Agostinho Neto International Airport, which has progressively replaced the city's older airport. The proposed flight schedule is detailed below. Flight Route Day Departure Arrival TP293 Porto–Luanda Friday 1:00 PM 10:10 PM TP293 Porto–Luanda Sunday 9:25 PM 6:35 AM +1 TP294 Luanda–Porto Monday 8:20 AM 3:45 PM TP294 Luanda–Porto Friday 11:55 PM 7:20 AM +1 The aircraft substitution will reduce weekly capacity from 1,192 to 684 seats across both directions, a reduction of 508 seats. TAP's A321LR configuration accommodates 16 business-class passengers and 155 economy passengers, compared with 34 business and 264 economy seats on its A330-900s. The smaller aircraft could allow TAP to better match capacity with demand while maintaining nonstop service. When TAP first received the A321LR, then-CEO Antonoaldo Neves explained its strategic importance: “With its superior range, we can comfortably explore new markets in North America, South America and Africa from Portugal, and offer nonstop flights with the right size of aircraft.” However, the long flight raises operational questions. Airbus advertises an A321LR range of approximately 4,000 nautical miles, equivalent to 4,603 miles (7,408 km), comfortably exceeding Porto–Luanda's great-circle distance of 3,737 miles (6,014 km) on paper. Nevertheless, the aircraft's range depends on payload and operating conditions. Heavy checked baggage, commercial cargo, headwinds, and fuel reserves could all influence its performance. TAP has not announced any passenger or baggage restrictions, and whether either will be necessary remains unknown. TAP's 10 Longest Nonstop Airbus A321LR Routes In 2027 Credit: Markus Mainka | Shutterstock The Porto–Luanda deployment will surpass TAP's Lisbon–Belém service by just 11 miles (18 km). The Portuguese flag carrier has increasingly used its A321LRs to connect smaller long-haul markets across the Atlantic, particularly in northeastern Brazil and North America. Its introduction of the aircraft transformed TAP's transatlantic network, allowing the airline to serve destinations previously impossible to operate economically because they would have required larger widebodies to cover the distance. TAP's planned 2027 A321LR network includes 16 nonstop routes exceeding 2,000 miles (3,219 km). Rank Nonstop A321LR route Distance Weekly flights 1 Porto – Luanda 3,737 mi (6,014 km) 2 2 Lisbon – Belém 3,726 mi (5,997 km) 6 3 Lisbon – Recife 3,628 mi (5,839 km) 7 4 Lisbon – São Luís 3,619 mi (5,824 km) 3 5 Lisbon – Washington Dulles 3,592 mi (5,781 km) 7 6 Lisbon – Toronto 3,576 mi (5,755 km) 7 7 Lisbon – Natal 3,496 mi (5,626 km) 7 8 Lisbon – Newark 3,385 mi (5,448 km) 11 9 Lisbon – New York JFK 3,367 mi (5,418 km) 7 10 Porto – Newark 3,340 mi (5,375 km) 6 Six of the ten longest connect Portugal with the Americas, three serve Brazil specifically, and the new Porto–Luanda service is the only African route on the list. The ranking illustrates the versatility of an aircraft that TAP originally introduced to complement its A330-900 fleet. Crucially, the record applies only to nonstop flights: TAP has operated longer one-stop A321LR services, including Lisbon–Belém–Manaus, covering a combined 4,534 miles (7,297 km). Introduced in November 2024, the three-weekly service was scheduled to take 11 hours and 45 minutes, including its stop in Belém. TAP has also just launched a triangular Lisbon–São Luís–Fortaleza–Lisbon service, demonstrating how intermediate stops extend the reach of its long-haul narrowbody fleet. Inside Luanda's New $3 Billion International Airport Credit: AlfonsoSM | Shutterstock The destination is itself undergoing a major transformation. Dr. António Agostinho Neto International Airport (NBJ) was inaugurated in November 2023, approximately 25 miles (40 km) south-east of central Luanda, replacing Quatro de Fevereiro Airport (LAD) as the city's principal passenger gateway. Angola's national carrier, TAAG Angola Airlines, transferred its international operations in October 2025, while the wider transition was completed in March 2026. The airport forms part of Angola's ambition to establish a major Southern African aviation hub. The approximately $3 billion facility is designed to handle 15 million passengers annually, supported by two runways and substantial cargo infrastructure. Metric Details Airport Dr. António Agostinho Neto International Inaugurated November 10, 2023 Construction cost Approximately $3 billion Distance from Luanda 25 mi (40 km) Annual capacity 15 million passengers 2025 passengers 756,028 Runways 2 Runway lengths 13,123 ft (4,000 m); 12,467 ft (3,800 m) Annual cargo capacity 130,000 metric tons Airlines TAAG Angola Airlines, TAP, Air France, Lufthansa, Ethiopian, Qatar Airways, Royal Air Maroc, Airlink However, its initial traffic has been considerably lower than anticipated. Just over 750,000 passengers used the airport during 2025, although that figure reflects a transitional year before all scheduled airlines had relocated. Despite its ambitious scale, the airport faces challenges attracting and retaining international services. Turkish Airlines removed Luanda from its network in 2026, following the withdrawal of Brussels Airlines last year. Nevertheless, TAP, Lufthansa, Air France, and several African carriers maintain connections. TAP's planned A321LR substitution illustrates how it is able to adjust capacity to demand and still maintain the nonstop service.
