Business jets are generally limited to a maximum of 19 passengers because this limit is specified in aviation legislation, particularly by the European Aviation Safety Agency (EASA) and the Federal Aviation Administration (FAA) in the US.
The main reason for this is that aircraft carrying up to 19 passengers are classified as “business jets” or “private jets.” As such, they are subject to certain regulatory requirements that are less stringent than those for larger commercial aircraft. This regulation facilitates the certification, operation, and maintenance of the jets, which reduces costs and bureaucratic effort.
In addition, this limitation allows for flexible use, as jets with up to 19 passengers are often used for private or business trips that do not require extensive passenger or security checks as is the case with commercial aircraft.
Even large jets such as the Gulfstream G650, Falcon 8X, or Bombardier Global Express are limited to a maximum of 19 seats. For larger groups, only corporate VIP airliners such as the Boeing BBJ or Airbus ACJ are available.
