historical_airlines

Real airlines that operated in a given year (1950-2030) as the game knows them: name, IATA code when reliably known, home country and region, type, years of operation, and the countries each one served that year. Network data has decade precision: a country listed for the 1960s may have been added mid-decade. servedCountries lists destinations from home; when networkKnown is false only the home country is known. Sorted by the airline size in the dataset.

Parameters5

year	integer	required	Calendar year, 1950-2030
country	string	optional	Home country of the airline, ISO 3166-1 alpha-2 (GB, US, FR)
region	string	optional	Game region of the airline base
kind	string	optional	flag carrier, major, regional, low-cost or charter
limit	integer	optional	At most this many airlines

aircraft_catalog

Aircraft types of the game catalog: seats in two classes, range, cruise speed, required runway, entry into service and end of production, and the list price in millions of US dollars of the entry-into-service year. With year, only types already flying that year are returned and availabilityInYear says whether they are sold new or only on the used market.

Parameters6

year	integer	optional	Only aircraft already in service in this year; also fills availabilityInYear
category	string	optional
manufacturer	string	optional	Substring, case-insensitive
query	string	optional	Substring of the model name or id, case-insensitive (A320, 747, dc-3)
limit	integer	optional

aircraft_price

In-game catalogue price of a new aircraft in a given year: the entry-into-service price inflated by US CPI to nominal dollars of that year, and the same price in 2024 dollars. Accepts an id from aircraft_catalog or part of the name; when several types match and the year does not settle it, returns candidates to choose from.

Parameters2

model	string	required	Aircraft id from aircraft_catalog (a320-200) or part of its name (A320, 747-400)
year	integer	required	Game year to price the aircraft in
