The complex life cycle of giant aircraft – and why you might be better off in an older model
At 19, the world's oldest commercial A380 is hardly ancient but – in aircraft years – it's reached an age at which most large jets (the affectionate nickname for all wide, long bodied aircraft) retire to the great boneyards of the desert. Not this one though: after a five-year hiatus, it's back ploughing the skies for Emirates, according to The European Union Aviation Safety Agency (EASA) says that most planes have a life cycle of around 25-30 years, but that includes a long period of research and development before their first commercial flights take off. If you find yourself on a comparatively ancient aircraft, don't worry: planes are subjected to frequent tests to ensure safety and usually retire because they become less commercially competitive rather than dangerous. A wide-body aircraft's journey involves a long period of incubation and subsequent nurturing before it can go out into the world. 'The journey from the design board to commercial service for a commercial aircraft is one of the most complex undertakings in modern industrial engineering,' says Linus Benjamin Bauer, founder and managing direction of the aviation consultancy BAA & Partners. 'Typically, the aircraft development programme takes up to 15 years to bring a new aircraft such as the A380 to market.' The original jumbo, Boeing's 747, was conceived in 1966 and began to fly commercially four years later thanks to tight deadlines imposed by its first purchaser, Pan Am. But, before paying passengers can get onboard, planes face 'initial conceptual studies, customer consultations, digital modelling, prototype development and regulatory certification,' according to Bauer. 'Certification itself is particularly rigorous,' he says. 'Manufacturers must demonstrate compliance with thousands of airworthiness requirements. Each new aircraft must pass a full-scale evacuation test – where all passengers must exit within 90 seconds using only half the available exits. Structural integrity is validated through static testing, where airframes are pushed 50 per cent beyond their design limits, and fatigue testing, which simulates decades of flight cycles.' These tests can make or break a plane's popularity: when they uncovered issues with weight in some of Boeing's earliest 787 aircraft (nicknamed the 'Terrible Teens'), the planes were rejected by airlines including All Nippon Airways and Royal Air Maroc, according to the website (though they now take to the skies with Ethiopian and Air Austral). The A380 also had a complicated conception. 'While technologically advanced, it was delayed by nearly two years due to a major production issue,' says Bauer. 'The wiring systems designed in Germany were incompatible with the French-built fuselage sections because they used different 3D modelling software versions. This misalignment triggered an expensive and [potentially] reputationally damaging cascade of redesigns.' Running costs affect the lifespan of an aircraft, as well as advancing technology and trends. The A380 is a hulk of a plane and its days have long been numbered, thanks to expenses linked to its size. In 2021, Emirates, the biggest fan of the aircraft with 121 in its fleet, took delivery of the last one ever made. It meant that the A380 had a much shorter run than the 747, which only went out of production in 2022, after more than five decades. Born out of a desire to fit more passengers into the cabin and raise per-seat profits, the 747 has been a huge success, with no competitors to match it in terms of seat capacity until the A380 came along 37 years later. Both aircraft continue to fly, with Forbes claiming there are 400 747s still in service (almost double the amount of A380s ever made). Keeping older planes going requires meticulous maintenance and careful piloting. New tech is retro-fitted and they often have makeovers to bring their cabins or liveries up to date too: in May 2025, Korean Air unveiled a 747-8i sporting its smart new blue look and logo. 'Over the course of a jet's life, it will undergo extensive maintenance and repair, but these do not imply degradation in safety,' says Bauer. 'On the contrary, aircraft become more stringently monitored as they age. Airlines conduct daily line checks, periodic A- and B-checks, and deep-dive C- and D-checks where the aircraft is virtually dismantled, inspected, and rebuilt every six to ten years. Engines are overhauled or replaced, flight control systems updated, and any structural fatigue is carefully monitored using non-destructive testing techniques. Safety margins remain extremely high, and ageing aircraft are continuously evaluated under regulatory oversight from authorities such as the Federal Aviation Authority and EASA.' But the shadow of retirement always lingers, because aircraft manufacturers are endlessly innovating to make their products lighter and more sustainable. It's been impossible to fly from the UK in a 747 since 2020, when both BA and Virgin Atlantic retired theirs (hop to Frankfurt, however, and you can board a Lufthansa 747-8 to one of 12 destinations, including Tokyo Haneda, Buenos Aires and Newark). President Trump also travels on the two, heavily customised 747s in the Air Force One fleet, and was recently gifted another one by the Qatari government. It will, however, require a bit of retrofitting if it is to serve in the fleet. 'The President and his travel companions enjoy 4,000 square feet of floor space on three levels, including an extensive suite for the President that features a large office, lavatory, and conference room. Air Force One includes a medical suite that can function as an operating room, and a doctor is permanently on board,' the White House website reveals. For normal passengers, A380s remain attractive: roomy, with a smooth ride, they're renowned for being comfortable on long-haul journeys while their First Class and Business cabins have space for plenty of onboard luxuries. There are even proper showers on some Emirates' A380s – which goes some way to explain the reluctance to decommission them by some airlines, despite 787s and A350s being more economical. In 2024, IATA revealed that the average age of a commercial aircraft was 14 years and 10 months, and the EASA states that almost a third of all of Europe's planes are due to be retired in the next decade. The lucky ones will live out their days in aerospace museums such as Paris's Musée de l'Air et de l'Espace in Paris Le Bourget. Others are dismantled so that approved working parts can be reused, and some cabin furniture finds its way into films and TV shows, offices and even homes. Much of what can't be reused, including titanium, aluminium and rubber, can be recycled, though about 15 per cent of waste ends up in landfill, according to the EASA. Among the retirees, there are bound to be more A380s and 747s because, in 2026, another giant is expected on the scene: the 777-9. Longer even than the 747-8, with the largest engines of any passenger plane, it should still cut fuel consumption by 10 per cent and has been ordered by British Airways, Singapore Airlines, Emirates and Lufthansa amongst others. 'The aircraft features new carbon-fibre composite wings, advanced GE9X engines, and a reimagined passenger cabin,' says Bauer. 'From my point of view, the 777X will effectively mark the end of the 747 in passenger service. While some 747-8is may remain in limited use, and freighter versions will continue for years due to their payload advantages, the age of four-engine passenger aircraft is over. It is not sentiment but economics – as well as evolving regulation on noise, emissions, and sustainability – that has redrawn the map. In this new landscape, efficiency, not size, is king.'
