The Economics of Airline Class

- The episode examines how the Concorde changed commercial aviation despite its commercial failure. Building on an earlier video about why planes do not fly faster, Wendover Productions argues that the Concorde helped shape the development of business class and the modern airline cabin.

- Premium cabins generate a disproportionate share of traditional airline revenue. Airlines make much of their money from premium economy, business class and first class rather than economy passengers. The episode argues that, on average, approximately two-thirds of airline passenger revenue comes from these three premium categories.

- A British Airways Boeing 777 illustrates the revenue imbalance. The example aircraft operates daily between London Heathrow and Washington Dulles, carrying 224 passengers: 122 economy, 40 premium economy, 48 business class and 14 first class passengers.

- Economy passengers generate surprisingly little revenue compared with premium passengers. Using the round-trip fares available at the time of the video, economy tickets cost $876 each, generating $106,872 if all 122 seats are occupied. Premium economy costs $2,633 per passenger, generating $105,320 across its 40 seats.

- Business class produces the largest revenue of the four cabins. At $6,723 per round-trip ticket, its 48 seats generate $322,704 when full. This is approximately three times the revenue generated by the 122 economy seats.

- First class earns more from 14 passengers than economy earns from 122. First-class tickets cost $8,715 each, generating $122,010 across 14 seats. The example demonstrates how a very small number of premium passengers can outperform a much larger economy cabin.

- Premium cabins collectively generate approximately $550,034 in the British Airways example. Premium economy, business and first class account for approximately 45% of passengers but 84% of the aircraft's ticket revenue. The remaining 55% of passengers in economy generate only 16%.

- The British Airways figures are unusually high and should not be treated as typical airline revenue. The example uses expensive nonstop fares between two wealthy, high-demand cities. The narrator explicitly cautions that airlines do not ordinarily earn half a million dollars from a six-hour transatlantic flight.

- Connecting passengers pay considerably less than passengers buying the same nonstop route. A passenger originating in Stockholm and connecting onto the London–Washington flight pays approximately $392 for economy, $1,150 for premium economy, $3,025 for business class and $5,564 for first class. Despite the lower fares, the broad distribution of revenue between premium and economy cabins remains similar.

- British Airways has an unusually premium-oriented aircraft configuration. Its 777 example contains a relatively large premium section, so it should not represent every airline. Nevertheless, the narrator maintains that premium cabins account for roughly two-thirds of passenger revenue across airlines on average.

- Early commercial aviation had no meaningful cabin-class system because flying itself was a luxury. Aircraft in the 1920s were not necessarily comfortable or luxurious, but flying was so expensive that the ability to travel by air was itself considered a premium experience.

- The early economics of flying resemble today's planned commercial space tourism. Virgin Galactic's proposed tourist flights do not need separate first, business and economy classes because the entire experience is expensive and exclusive. The narrator predicts that differentiated classes will emerge once space travel becomes sufficiently commonplace and affordable to ordinary customers.

- A 1950 economy-class ticket could cost as much as modern first class. A round-trip coach fare between New York and London cost $675 in 1950, equivalent to approximately $6,800 in contemporary money. This was roughly the price of a first-class ticket on the same route at the time of the video.

- The historical development of airline classes is primarily a story of making flying cheaper, not simply making premium seats more luxurious. The people occupying today's first-class seats are comparable to the passengers who could afford to fly in 1950. What changed was the ability to reduce costs and allow people with less money to travel in the same aircraft.

- Airlines use different prices to sell essentially the same transportation product to different customers. Every passenger is purchasing a journey from one place to another. The differences lie in the onboard experience, flexibility, conditions attached to the ticket and the amount each customer is willing to pay.

- The earliest airline class distinctions developed during the 1940s and 1950s, partly around US Postal Service air-mail contracts. Airlines earned significant revenue operating contracted mail routes. These flights frequently made multiple stops and operated overnight or at inconvenient hours, but they also carried passengers.

- Early first-class and coach fares could purchase substantially different journeys rather than different seats. A first-class passenger might obtain a nonstop New York–Chicago flight, while a cheaper coach ticket might place someone on a mail-carrying service departing at 2 a.m. and stopping in Pittsburgh and Cleveland. The onboard passenger experience was largely the same; the principal difference was convenience and journey duration.

- 1952 marked an important change: airlines began selling different prices for the exact same flight. One airline offered a standard one-way New York–London ticket for $395 and a tourist-class ticket for $270. Both passengers travelled on the same aircraft and flight, with the difference embedded in the ticket conditions rather than the physical journey.

- Tourist-class tickets were deliberately designed for passengers willing to sacrifice flexibility for a lower price. They had to be purchased in advance and were valid only for the specific flight booked. This suited tourists, who generally planned their journeys well ahead of time and did not need the freedom to change flights.

- Full-fare tickets targeted business travellers with different purchasing behaviour. Business travellers frequently had their tickets paid for by employers, making them less personally sensitive to price. They also needed flexibility and often booked at the last minute, sometimes simply walking up to the airport counter an hour before departure.

- Airlines had discovered a way to segment customers according to their willingness to pay. Tourists received cheaper, restrictive tickets, while business travellers paid more for flexibility and convenience. This became the principal large-scale classification system in commercial aviation for several decades.

- Three developments between 1969 and 1978 transformed the airline cabin: the Boeing 747, the Concorde and US airline deregulation. The 747 provided the physical space to experiment with luxury, the Concorde gave airlines a competitive reason to develop premium experiences, and deregulation gave them greater freedom to set prices.

- US airline deregulation fundamentally changed how carriers could price their services. Previously, airfares were heavily regulated, restricting airlines' ability to charge the prices they wanted for different passenger categories. Deregulation gave airlines control over their ticket prices and greater freedom to develop differentiated products.

- Airlines increasingly needed to distinguish business travellers from tourists inside the aircraft itself. More business travellers were purchasing discounted tourist-class tickets instead of full-fare coach tickets. Airlines responded by giving full-fare passengers a more exclusive experience, rather than relying entirely on ticket restrictions.

- The first physical distinction between full-fare and discounted passengers was seating location. Full-fare passengers were moved to the front of the aircraft, while discounted passengers were placed at the back.

- Some airlines began blocking the middle seat beside full-fare passengers. This created additional personal space and made the more expensive ticket attractive without initially requiring an entirely separate premium cabin.

- Airlines subsequently introduced dedicated cabins with better seats and amenities. These developments gradually transformed the distinction between business and economy from a difference in ticket conditions into a visibly different onboard experience.

- Airlines initially avoided introducing first class on ordinary subsonic aircraft because they expected the Concorde to dominate the highest luxury market. With exceptions, carriers concentrated on developing business class as the premium offering for conventional aircraft. The expectation was that the Concorde would serve the rich and famous, while regular aircraft would primarily offer business and economy.

- The anticipated dominance of the Concorde contributed to airlines delaying the development of conventional first-class cabins. Airlines in the 1970s and 1980s largely avoided first class because they believed supersonic travel would occupy that market.

- The Concorde's spectacular commercial failure eventually forced airlines to reconsider their strategy. As carriers recognised that supersonic passenger travel would not become the expected dominant luxury alternative, selected airlines gradually reintroduced first class on conventional subsonic aircraft.

- The Concorde's influence remains visible in the limited availability of first class on transatlantic routes. Of the dozens of airlines operating transatlantic services, only six have a first-class cabin. The narrator connects this unusual outcome to the industry's earlier expectations about supersonic competition.

- The threat of the Concorde accelerated the development of business class. The prospect of a dedicated aircraft for wealthy passengers encouraged conventional airlines to improve the middle premium market earlier than they otherwise might have. The narrator argues that business class probably would not have developed as early without that perceived competition.

- First class is now disappearing from conventional aircraft for a different economic reason. Airlines are increasingly removing first-class cabins and replacing them with additional business-class seats because business class can generate more revenue from the available aircraft space.

- An Etihad Airbus A380 illustrates the difference in space consumption between cabin classes. Each economy seat occupies approximately 3.77 square feet (0.35 m²), each business-class seat occupies 10.14 square feet (0.94 m²), and each first-class seat occupies approximately 35 square feet (3.25 m²).

- The Etihad Abu Dhabi–New York example shows substantial differences in ticket prices. Round-trip economy tickets cost $1,253, business-class tickets cost $6,140 and first-class tickets cost $14,128.

- Business class produces the highest revenue per square foot in the Etihad example. Based on the fares and floor-space allocations presented, economy generates approximately $332 per square foot, business class $605 and first class $403.

- First class consumes disproportionately large amounts of aircraft space relative to the revenue it produces. A first-class seat occupies more than three times the floor area of a business-class seat, but its higher ticket price does not compensate sufficiently for that additional space.

- The difference between economy and business class is more commercially meaningful than the difference between business and first class. Economy passengers receive cramped seating, while business passengers can enjoy a bed. By comparison, first class often offers business passengers only somewhat more space and better food.

- Airlines struggle to charge enough of a premium for first class to justify its operating economics. Although first-class tickets cost more, the cabin requires substantially more space and costs more to operate. The relatively small improvement over business class makes the additional expense difficult to recover.

- Replacing first class with more business-class seats can increase airline revenue. Business class generates approximately $605 per square foot compared with first class's $403 in the Etihad example. Airlines therefore have a financial incentive to remove first-class accommodation and use the space for additional business-class passengers.

- Airlines would prefer to operate aircraft entirely filled with business-class passengers if demand allowed it. The narrator notes that this model has been attempted, but virtually no route has enough premium demand to fill an entire aircraft with business travellers.

- Economy class remains necessary to fill aircraft and make routes commercially viable. Premium passengers generate a disproportionate share of revenue, but the larger economy cabin supplies the passenger volume needed to occupy the aircraft. In the narrator's formulation, economy passengers are ultimately there to fill the plane.
