A minibus, microbus, or minicoach is a passenger carrying motor vehicle that is designed to carry more people than a multi-purpose vehicle or minivan, but fewer people than a full-size bus.
 In the United Kingdom, the word "minibus" is used to describe any full-sized passenger carrying van.
 Minibuses have a seating capacity of between 8 and 30 seats.
 Larger minibuses may be called midibuses.
 Minibuses are typically front-engined step-entrance vehicles, although low floor minibuses do exist.
On April 7, 1994, Federal Express Flight 705, a McDonnell Douglas DC-10-30 cargo jet carrying electronics equipment across the United States from Memphis, Tennessee to San Jose, California, was nearly hijacked by Auburn Calloway, who the prosecution argued was attempting to commit suicide.
 Calloway, a Federal Express employee, was facing possible dismissal for lying about his flight hours.
 He boarded the scheduled flight as a deadhead passenger carrying a guitar case concealing several hammers and a speargun.
 He intended to switch off the aircraft's cockpit voice recorder before take-off and, once airborne, kill the crew with hammers so their injuries would appear consistent with an accident rather than a hijacking.
 However, the CVR was switched back on by the flight engineer, believing that he had neglected to turn it on.
Irruptive growth, sometimes called Malthusian growth, is a growth pattern over time, defined by population explosions and subsequent sharp population crashes, or diebacks.
 It is an extension of the Malthusian growth model, specifically the growth pattern that causes a Malthusian catastrophe, and can occur when populations overshoot their carrying capacity, a phenomenon typically associated with r-strategists.
 Populations which exhibit irruptive growth do not stabilize around their carrying capacity, a feature of logistic growth.
 Irruptive growth occurs when a species reproduces more rapidly than the environment is capable of supporting with the available resources.
 Irruptive growth is studied in population ecology.
In population ecology and economics, maximum sustainable yield or MSY is theoretically, the largest yield (or catch) that can be taken from a species' stock over an indefinite period.
 Fundamental to the notion of sustainable harvest, the concept of MSY aims to maintain the population size at the point of maximum growth rate by harvesting the individuals that would normally be added to the population, allowing the population to continue to be productive indefinitely.
 Under the assumption of logistic growth, resource limitation does not constrain individuals’ reproductive rates when populations are small, but because there are few individuals, the overall yield is small.
 At intermediate population densities, also represented by half the carrying capacity, individuals are able to breed to their maximum rate.
 At this point, called the maximum sustainable yield, there is a surplus of individuals that can be harvested because growth of the population is at its maximum point due to the large number of reproducing individuals.
 Above this point, density dependent factors increasingly limit breeding until the population reaches carrying capacity.
 At this point, there are no surplus individuals to be harvested and yield drops to zero.
 The maximum sustainable yield is usually higher than the optimum sustainable yield and maximum economic yield.
The International Air Transport Association (IATA ) is a trade association of the world’s airlines.
 Consisting of 278 airlines, primarily major carriers, representing 117 countries, the IATA's member airlines account for carrying approximately 83% of total Available Seat Kilometers air traffic.
 IATA supports airline activity and helps formulate industry policy and standards.
 It is headquartered in Montreal, Quebec, Canada with Executive Offices in Geneva, Switzerland.
The Subaru Baja "(pronounced ba-ha)" is an all-wheel-drive, four passenger, four-door, open-bed pickup truck manufactured from 2002 to 2006 by Subaru and marketed for model years 2003 to 2006.
 The Baja combines the handling and passenger carrying characteristics of a traditional passenger car with the open-bed versatility, and to a lesser degree, load capacity of a pickup truck.
 The Baja nameplate derives from Mexico's noted peninsula of the same name — home to the Baja 1000 off-road race.
Payload is the carrying capacity of an aircraft or launch vehicle, usually measured in terms of weight.
 Depending on the nature of the flight or mission, the payload of a vehicle may include cargo, passengers, flight crew, munitions, scientific instruments or experiments, or other equipment.
 Extra fuel, when optionally carried, is also considered part of the payload.
 In a commercial context (i.e., an airline or air freight carrier), payload may refer only to revenue-generating cargo or paying passengers.
Oneworld (marketed as oneworld; CRS: *O) is an airline alliance founded on 1 February 1999.
 The alliance's stated objective is to be the first-choice airline alliance for the world's frequent international travelers.
 Its central alliance office is currently based in New York City in the United States.
 Its member airlines include Air Berlin, American Airlines, British Airways, Cathay Pacific, Finnair, Iberia, Japan Airlines, LATAM Airlines, Malaysia Airlines, Qantas, Qatar Airways, Royal Jordanian, S7 Airlines and SriLankan Airlines, plus some 21 affiliated airlines.
 As of August 2016, Oneworld is the third largest global alliance in terms of passengers with more than 557.4 million passengers carried, behind Star Alliance (689.98 M) and SkyTeam (665.4 M).
 Its slogan is "An alliance of the world's leading airlines working as one."
Available seat miles (ASM) or Available seat kilometres (ASK) is a measure of an airline flight's passenger carrying capacity.
 It is equal to the number of seats available multiplied by the number of miles or kilometres flown.
 An available seat mile is the fundamental unit of production for a passenger-carrying airline.
 A unit in this case is one seat, available for sale, flown one mile.
 For example, an aircraft with 300 seats available for sale flying 1,000 statute miles would generate 300,000 ASMs for that particular flight.
 That the seats are available for sale is critical.
 An aircraft that had 300 seats but which was limited (for regulatory or technical reasons) to selling only 250 of them on a particular flight of 1,000 miles would generate 250,000 ASMs on that flight, not 300,000.
 Similarly, if passenger seats on a particular flight are dedicated to crew rest purposes, such seats would not be included in the calculation of ASMs for that flight.
Tourism carrying capacity is a now antiquated approach to managing visitors in protected areas and national parks which evolved out of the fields of range, habitat and wildlife management.
 In these fields, managers attempted to determine the largest population of a particular species that could be supported by a habitat over a long period of time.
 Many authors, such as Buckley, Wagar, Washburne, McCool, and Stankey have critiqued the concept as being fatally flawed in both the conceptual assumptions made and its limited practical application.
 For example, the notion of a carrying capacity assumes the world, such as the social-ecological systems in which protected areas and tourism destinations are situated, are stable.
 But we know they are dynamically complex and impossible to predict.
 We know that to implement a carrying capacity on a practical level, assumes a level of control of entries into a destination or protected area not usually found in the real world.
 We know that a carrying capacity, if one could be determined, requires considerable financial and technical resources to administer; and we know that when demand exceeds a limit, the ways in which scarce opportunities are allocated are contentious.

Question: What percentage of the measure of an airline flight's passenger carrying capacity does the IATA's member airlines account for?
Answer: 83%
