The world's largest passenger jet took flight for the first time 18 years ago. See the full history of the Airbus A380 superjumbo from marvel to reject.

The iconic Airbus A380 double-decker jet is the world's largest passenger plane. It flew for the first time ever on April 27, 2005 with six people onboard.

The three-hour and 54-minute flight over France was the first in a series of test flights, with captain Jacques Rosay praising the jet's performance: "Within the first minutes of the flight, we were struck by the aircraft's ease of handling."

When the jet finally hit the market in October 2007 with Singapore Airlines, it was supposed to be a revolutionary addition to the aviation industry.

However, the plane's inefficient design and high operating costs forced airlines around the world to abandon the jet in favor of smaller, two-engine widebodies, like the Airbus A350 and the upcoming Boeing 777X.

While there are a few global carriers that still operate the A380 — like its biggest customer Emirates — carrier loyalty has faded. Here is the full history of the superjumbo, from marvel to reject.

Lufthansa announced its first post-pandemic Airbus A380 destination will be to the US. Here are the airlines that have resumed flying the plane since 2020.

During the 1970s, Airbus' A300B was the new kid in the world of commercial airliners.

It spent the decade trying to break into a market dominated by the Boeing 747 jumbo jet, which had an incredible size, performance, and efficiency that lowered operating costs to make air travel accessible for the masses.

No longer was air travel reserved for the rich and famous, and, in fact, the Boeing 747 had the lowest seat-mile cost in the industry at the time. But, Airbus was starting to catch up.

By the early 1990s, Airbus was in a much different position. Its narrow-body A320 family, which helped pioneer civilian fly-by-wire technology, was well on its way to becoming the second-best-selling jetliner in history.

At the same time, the company unveiled its new A330...

...and A340 family widebody jets. The two aircraft offered viable alternatives to Boeing's 767 and 777 widebodies. But Airbus has set its sights on a bigger target: Boeing 747-400.

Airbus' goal was to produce an aircraft even bigger than Boeing's latest jumbo jet — with lower operating costs.

The result was a double-decker concept called the A3XX.

The A3XX would eventually morph into the A380 superjumbo.

Before Airbus ended its production in November 2021, the A380 was built in a 1.6-million-square-foot assembly plant at Airbus' headquarters in Toulouse, France.

At 239 feet long, 79 feet tall, and 262 feet from wingtip to wingtip, it's a big plane.

Only the Boeing 747-8 is longer, at 250 feet and two inches — but the A380 can carry many more passengers.

According to Airbus, in a typical four-class seating arrangement, the superjumbo can carry as many as 544 passengers, with a range of more than 9,400 miles.

In a high-density configuration, the A380 is certified to carry as many as 853 passengers. No airline ever opted for this layout, though French carrier Air Austral almost went through with the idea in 2009.

Power for the A380 comes from a quartet of engines from suppliers Rolls-Royce and Engine Alliance.

The A380's flight crew operates from a state-of-the-art glass cockpit. Like all modern Airbus jets, the aircraft is flown using a side stick, with a fly-by-wire control system.

As an airliner, the A380 promised luxury and comfort on an unprecedented scale.

And, the Airbus jumbo delivered, at least to airlines that wanted to take advantage of luxurious options. Premium features, such as walk-up bars...

...private lounges...

...and bathrooms with showers set the A380 apart from its rivals.

And then there are the beautiful first-class suites from carriers like Emirates...

The allure of the A380 soon drew in dozens of orders from several other global carriers, like Thai Airways...

...Korean Air...

...All Nippon Airways...

Despite a few years of success, the plane's popularity started to fall as the decade went on, especially as Airbus was reluctant to invest the kind of money needed to develop a new version of the A380.

In 2017, Airbus did offer its customers a moderately updated version of the jet, called the "A380plus," with room for 80 more people and new winglets for better fuel economy. But, it never made it to production.

While many carriers lost their love for the A380, one airline has never wavered — Dubai-based Emirates, which accounts for 118 of the 274 total A380s ordered by airlines.

Emirates is a predominantly long-haul international airline. Its business is built around funneling millions of passengers through its palatial central hub in Dubai and then on to destinations around the world.

As a result, Emirates needs an aircraft that can carry a lot of passengers for very long distances — a perfect job for the A380.

But few airlines use Emirates' strategy. These days, the trend in the industry is to offer direct flights using smaller long-range aircraft — especially as travelers prefer nonstop routes rather than having a layover in a hub city.

Because of the industry shift, most airlines have moved towards point-to-point flying. This has allowed smaller, more efficient twinjets like the Boeing 777...

...and the Airbus A330 to become the dominant forces in long-haul flying.

Other next-generation composite widebodies like the Boeing 787 Dreamliner offer airlines more flexibility and less risk. According to Qantas CEO Alan Joyce, it costs less to operate two Dreamliners than it does to fly a single A380.

However, there was once a glimmer of hope for the A380 project thanks to Emirates, which ordered 20 additional jumbos in January 2018 that would have kept the production line moving for the next decade.

But, that deal fell apart. In the end, even the A380's most loyal customer couldn't hold on any longer, with Emirates cutting 39 A380s from its original order of 162 planes and opting for smaller twin-engine Airbus A330neos and A350s instead.

As a result, the A380 never developed into a true workhorse like the 747. Instead, it has been relegated to a niche aircraft economically feasible only on routes with heavy airport congestion.

In 2017, Singapore Airlines became the first airline to retire an A380, the first of five to be taken out of service. Many were scrapped, with one going to Portuguese charter company Hi-Fly.

In November 2019, Air France became the second. The airline quietly took the plane out of service after a flight from Johannesburg to Paris despite the airline previously announcing it would retire its 10 A380s by 2022.

Through March and April 2020 as the COVID-19 pandemic led to sharply reduced travel demand all around the world, numerous airlines grounded their A380 fleets.

However, not all airlines were ready to say goodbye to the iconic double-decker just yet. China Southern only briefly grounded the jet between February 10 and March 24, 2020, according to Cirium data, and has continued to fly them.

Meanwhile, Emirates unsurprisingly relaunched the jet early in the pandemic, flying it from London to Paris in July 2020.

About a year and a half later, the Dubai-based operator received the last-ever A380 to be produced, marking a significant milestone for the airline.

The final A380s have a 4-cabin configuration with Emirates' sophisticated Premium Economy section, complete with wide, spacious seats, a leg rest, and greater recline.

In addition to China Southern and Emirates, Korean Air has also decided to unretire the double-decker jet, flying it for the first time since the pandemic from Seoul to New York-JFK on June 27.

Meanwhile, Germany-based Lufthansa announced in June that it was bringing the plane back in 2023.

Lufthansa is bringing back its beloved A380 jet next year, reversing a pandemic-era decision. Here are the airlines that have resumed flying the plane since 2020.

So, even though the A380 program ended in 2021, and many have already been retired, the planes are expected to fly on for years to come.
