Did you know these astonishing facts about your favourite airlines?

Just plane cool

The aviation industry is, indeed, flying. Airline profitability is up following a serious hit from the COVID-19 pandemic, with an estimated 4.7 billion people expected to take to the skies by the time 2024 draws to a close. As we enter this exciting new era for aviation, we take a closer look at some of the world's leading airlines.

Strap yourself in and discover some of the most fascinating facts about your favourites...

This airline has been going for more than a century

Dutch operator KLM – whose full name Koninklijke Luchtvaart Maatschappij means Royal Aviation Company – is the oldest airline still running. It was founded in 1919 and began operating flights between London and Amsterdam the following year. Today, it’s part of the Air France-KLM group following a merger in 2005, although flights still run under the KLM name.

The first-ever business class

Up until the early 1970s, flying on a plane meant a choice between fancy first class or basic economy seats. But in that decade, a number of airlines began to realise business travellers wanted something in between, and began marketing a section of economy seats to businesspeople. In 1979, Qantas was the first to offer an exclusive Business Class ticket as we know it today, with wider, more comfortable seats, improved food options and free drinks as well as access to a lounge. Pictured is one of its current business class seats.

American Airlines hired the world’s first female pilot

In 1960, 12-year old Bonnie Tiburzi took her first flying lesson and within a few years was a skilled aviator. She told her father, who ran the flight school, that she wanted to be a pilot when she grew up, but he didn’t take her seriously. After tirelessly applying for pilot jobs for several years, she was finally accepted by American Airlines in 1973, at the age of 24, becoming the first female pilot in the world.

This budget airline started with just £1 ($1.32)

According to its website, Irish low-cost carrier Ryanair started off with just £1 ($1.32) of share capital. The budget airline was started by (you guessed it) the Ryan family in 1985, and its first route operated on a 15-seater plane between Waterford, Ireland and London Gatwick. Cabin crew had to be less than five-foot-two-inches-tall (157cm) to fit onto the tiny planes. Seen here is Jane O'Keeffe, Ryanair’s one-millionth passenger, in 1988.

Ditching olives saved one airline a fortune

In 1987, American Airlines wanted to cut costs, so the company removed a single olive from each plate of salad served in first class. The total saving of this small action was reportedly a whopping £30,114 ($40,000) a year. Meanwhile, in 2011, Northwest Airlines allegedly saved £376,432 ($500,000) a year by cutting limes into 16 slices instead of 10.

The first online check-in was over 20 years ago

Nowadays, many travellers opt to check-in digitally and save time at the airport. This is a relatively new invention, though not as new as you might think. In September 1999, Alaska Airlines was the first operator to offer online check-in as the dot-com era boomed. The first customer to use the service, Kathy Bloom, was part of a tech company trialling the process and said at the time: “I found the process easy and quick, and I'm for anything that will save time at the airport.” We couldn’t agree more, Kathy.

There was a Spice Girls-themed plane

British pop sensation Spice Girls launched their first album with the Virgin record label in 1996. So in 2007, Virgin Atlantic named a Boeing 747 jet in their honour. The name, Spice One, was chosen after the musical group held a competition online, inviting fans to submit their suggestions.

One airline offers cry warnings before emotional movies

Virgin Atlantic once conducted a survey on its Facebook page in which 55% of women and 44% of men said they felt more emotional while on a plane. In response, the airline began issuing warnings (pictured) at the beginning of particularly sad in-flight movies, advising viewers to keep a box of tissues at the ready and call if they needed a shoulder to cry on. It’s thought that heightened emotions could be caused by increased oxytocin levels during travel.

This airline serves 25 million cups of tea

In news that’s probably not so shocking to British readers, the airline which serves up a whopping 25 million cups of tea per year is, of course, British Airways. So it was no surprise when in 2013 the carrier teamed up with Twinings to produce its own blend. The signature tea is specially developed to taste as good as possible at 35,000 feet (10,668m), allowing for the fact that food and drinks taste different due to reduced air pressure and humidity.

Some airlines allow falcons onboard

You’ve heard of Snakes on a Plane. Now get ready for its budget spinoff: falcons on a plane. Believe it or not, these feathered creatures are allowed on flights offered by several major carriers, including Qatar, Emirates, Etihad and Royal Jordanian Airlines. That’s because falcons are seen as a status symbol in some parts of the Middle East, so much so that some falcon-owners have been allowed to bring them onto planes. As of November 2023, nearly 22,500 falcon passports were issued in the UAE alone.

This is the world’s most expensive plane ticket

Launched in 2014, the Etihad Residence is the most luxurious flying experience you could conceive of. But it doesn’t come cheap: at up to £50,000 ($66,000) for a one-way ticket, it’s the most expensive plane ticket in the world. Included in the price is a limo ride to the airport, a personal butler on the plane, access to Etihad’s First Class lounge, gourmet dining options and a queen-sized bed onboard.

The longest-serving flight attendant worked for 65 years

It’s thought that 88-year-old Bette Nash was the oldest and longest-serving flight attendant in the world, having had a career that spanned 65 years. The octogenarian, pictured here in 2017, began working as cabin crew at Eastern in November 1957, and worked for American Airlines right up until May 2024, when she sadly lost her battle with breast cancer. In 2017, the airline marked Nash’s 60-year work anniversary by donating £7,540 ($10,000) to Sacred Heart Catholic Church Food Bank, where she regularly volunteered.

The longest non-stop flight takes almost 19 hours

Lasting a total of 18 hours and 50 minutes, Singapore Airlines’ 9,536.5-mile (15,348km) flight from New York JFK to Singapore is the longest direct flight in the world. The route was added on 11 October 2018 – pictured here is one of the first passengers on the inaugural flight.

This was the fastest subsonic flight

According to flight tracking platform Flightradar24, the average flight between London and New York takes just over six hours. But on 9 February 2020, a British Airways flight achieved the distance in a speedy four hours and 56 minutes, making it the fastest subsonic flight between the two cities. The Boeing 747 was aided by strong winds from Storm Ciara, which helped it to reach a top speed of 825 miles per hour (1,328km/h).

The world’s most frequent flyer has flown 24 million miles

Even during the pandemic, the world’s most frequent flyer managed to rack up a million miles (1.6 million km) in just nine months, while most of us wouldn’t be able to fly that far in a lifetime. Tom Stuker hit his most recent landmark of 24 million miles (38.6 million km) in May 2024. All of those air miles were flown with United, which makes him a Global Services member (the highest tier on the airline’s reward scheme) more than five times over. He fell in love with flying after travelling to Australia for work in 1984 and since then he’s become a self-confessed “flying junkie”.

This airline runs the most flights of all

US airlines rule the global rankings when it comes to the number of flights they offer per month. In September 2024, American Airlines had a whopping 176,319 flights, according to aviation data source OAG. American carriers Delta, United and Southwest came in second, third and fourth place respectively, while European airline Ryanair was fifth.

The largest fleet has 971 planes

It’s perhaps no surprise then, that American also has the largest fleet with 971 planes in total. Of those, the most popular is the Boeing 737, of which the carrier has 366. Out of the top 10 largest fleets globally, five are American companies.

This airline is the world's safest

Nervous flyers should book with Air New Zealand if they want to steady their nerves: the airline came top of AirlineRatings.com's safest airline rankings for 2024. The airline safety and product rating website evaluated factors such as serious incidents, fatal accidents, industry audits, pilot training and fleet age. Air New Zealand edged out 2023's winner Qantas, which came second, by just 1.5 points. Virgin Australia, Etihad and Qatar Airways came third, fourth and fifth places respectively.

This airline is an all-round award-winner

Based on customer surveys, SKYTRAX has been running its World Airline Awards since 1999, and in that time Qatar Airways has won eight times. The Doha-based carrier won 2024's award, based on data from millions of travellers. The main areas which the survey evaluated were comfort, fine cuisine, in-flight entertainment and punctuality. The airline also scooped the awards for best Business Class, world's best Business Class lounge and the best airline in the Middle East.

This airline offers the best cabin crew

SKYTRAX’s 2024 survey also shed light on the airline with the best cabin crew – this time Singapore Airlines came out trumps. According to their website, staff undergo a rigorous four-month training programme which is “one of the longest and most comprehensive in the airline industry” before they’re able to take to the skies. The airline also won world's best First Class and also best airline in Asia.

This airline tops the low-cost charts

Not everyone can afford to spend megabucks on a single flight, so it’s a good thing budget airlines are upping the ante to provide high-quality service to passengers at a lower cost. AirAsia was awarded the best low-cost carrier for the 14th year in a row by SKYTRAX and has been recognised by the Business Traveller Asia-Pacific Awards and other industry accolades for its budget offering.

Virgin Atlantic flew the world's first transatlantic 100% SAF flight

When United Airlines flew the world’s first-ever passenger flight using 100% sustainable biofuel in December 2021, between Chicago O’Hare and Washington DC’s Reagan National Airport, it showed what a lower-emissions aviation future could look like. Fast-forward to November 2023 and Virgin Atlantic went one better by flying the world's first transatlantic flight on 100% sustainable aviation fuel (SAF) from London Heathrow to New York JFK. The Boeing 787 made the historic flight, marking a significant milestone in the industry and proving the sky really is the limit.
