The travel and tourism industry is one of the most competitive in the world. In 2023, its direct contribution to global GDP reached approximately £8.1 trillion ($9.9tn), accounting for a significant 9.1% of the world's economy. With an enormous 1.3 billion international tourist arrivals taking place last year, 2024 is set to break even more records.

The most visited country in the world in 2023 was France, with roughly 100 million international tourist arrivals. The country also topped the list in 2022, while Spain claimed top spot during a pandemic-hit 2021. This year Spain finished second with 85.2 million arrivals, while the United States rounded out the podium with 66.5 million. Italy, Turkey, Mexico and the United Kingdom followed, in that order.

Around 8.9 million people – a staggering figure roughly equal to the population of Switzerland – visited the Louvre in Paris in 2023, making it the most visited museum in the world by some margin. That number is still not as high as it was before the pandemic in 2019, when 9.6 million people passed through its doors. Other big hitters include the Vatican Museums in Rome and London's British Museum.

According to the International Air Transport Association (IATA), around 4.5 billion people flew on commercial flights in 2019, reaching an all-time high. The Asia-Pacific region was the busiest, carrying 34.7% of global passengers, with Europe and North America following on 26.8% and 22.2% respectively. After plummeting during the pandemic, 2023 saw total passenger numbers top 4.3 billion, almost within touching distance of pre-pandemic levels.

FlightRadar24 data shows that the peak number of planes ever recorded to fly in a single day was on Thursday 25 July 2019, when 230,000 aircraft took to the skies. The figure represents almost every trackable aircraft in the world, but excludes sensitive air traffic like military flights, meaning that the actual number could be much higher.

Boeing and Airbus have long fought to produce the world's most popular plane. For a long time the title was held by Boeing's 737 jetliner, but its direct competitor, the Airbus A320, overtook it in scheduled flights in late 2019. That same year saw the A320 family also overtake the 737 for total orders, and the 737 has trailed its rival on both metrics ever since.

Currently, the world's longest scheduled non-stop commercial flight is the Singapore Airlines route between Singapore and JFK in New York City (flights SQ23 and SQ24). The flight takes nearly 19 hours to complete and covers 9,537 miles (15,347km). This might not be the longest flight for much longer, though, as Qantas has spent years preparing to launch direct non-stop flights from Sydney to London and New York. Codenamed Project Sunrise, the flights are expected to surpass the 19-hour mark, and are set to debut sometime in late 2025.

Which airline is largest depends on how you define 'largest'.  As of October 2024, American Airlines continues to have the largest fleet size globally, with 952 aircraft and more on order.​ In terms of revenue, however, Delta Air Lines leads the pack. Delta posted a record revenue of approximately £43.5 billion ($54.7bn) in 2023, outperforming American Airlines, which reported £42.3 billion ($53.4bn)​. Qantas and other US airlines continue to expand rapidly, but these metrics make American Airlines the largest by fleet and workforce, while Delta dominates in revenue.

For more than 20 years, Atlanta Hartsfield-Jackson (ATL) claimed the top spot as the world's busiest airport. But when global passenger numbers dropped by 64.6% due to the pandemic in 2020, the title went briefly to Guangzhou Baiyun International Airport in China, which serviced more than 43 million passengers that year. Atlanta regained its crown in 2021 and has retained it ever since, serving 104.7 million passengers in 2023.

The shortest scheduled airline flight is from the Scottish island of Westray to its neighbouring island, Papa Westray. The flight, operated by Loganair, takes an average of one-and-a-half minutes from take-off to landing and covers 1.7 miles (2.7km) – almost the same length as the runway at Edinburgh Airport.

A popular story often shared among budding entrepreneurs is that by removing one olive from each salad in first class nearly 30 years ago, American Airlines saved an astonishing £32,000 ($40,000) a year. It has also been rumoured that Northwest Airlines (before it merged with Delta), saved half a million dollars by cutting limes into 16 slices rather than 10.

The largest passenger plane in the world is the Airbus A380. It’s a double-decker, wide-body, four-engine jet airliner that provides seating for more than 500 people in a typical three-class configuration (economy, business and first class) or up to 853 seats in an all-economy setting. The aircraft is no longer produced by Airbus and the final A380 delivery took place in December 2021, when the last of these giant planes was delivered to Emirates.

An innovative plane with a wingspan of 385 feet (117m), the Stratolaunch Roc is wider than an American football field. The double-fuselage plane is designed to carry and launch hypersonic vehicles and rockets mid-air. In October 2022, the Stratolaunch successfully carried its first hypersonic vehicle passenger to an altitude of 23,000 feet (7,010m) above California's Mojave Desert. Many more tests have followed, and in June 2024 the plane reached a new-record operational altitude of 35,000 feet (10,700m).

Royal Caribbean's Icon of the Seas became the largest cruise ship on the ocean when it set off on its maiden voyage in January 2024. It's a whopping 1,198 feet (365m) in length, with 20 decks and a 2,350-strong crew. Some 7,600 passengers can be accommodated onboard, and they can enjoy seven swimming pools and more than 40 restaurants. It took the crown from sister ship Wonder of the Seas, which has a length of 1,187 feet (362m), 18 decks and a crew of 2,300.

For avid cruising enthusiasts, Royal Caribbean International offers the Ultimate World Cruise: a record-breaking 274-night journey aboard Serenade of the Seas. This voyage, which departed from Miami in December 2023, visits all seven continents, over 150 destinations and 65 countries. Originally set to sail through the Red Sea, the route was altered due to geopolitical tensions, with passengers voting to explore Africa’s southern and western coasts instead. The cruise is now en route to destinations like Madagascar, Namibia and South Africa. Prices for this epic adventure started around £45,400 ($61,000)​.

It serves as a crucial high-speed link under the Swiss Alps, connecting central and southern Europe. Following a freight train derailment in August 2023, the tunnel was temporarily closed for extensive repairs. After more than a year of work, it fully reopened to rail traffic on 2 September 2024.

It totals around 19,000 miles (30,000km) and would take three months to drive with an average eight hours of driving per day.
