(IATA: {{{1}}}, ICAO: {{{2}}}, call sign: {{{3}}})
This template is used to display an airline's identifiers or 'airline codes'. In Airline articles, the {{Infobox airline}} template should be used instead of this template. If an infobox with correct codes is already on the page, this template is not required.
Each of the three unnamed parameters can be used or omitted. For instance, for a military airbase which is also an aeronautical authority assigned an ICAO code but no IATA code, the first parameter can be left blank (void):
*[[RAF Scampton]] {{Airline codes|<!--no iata-->|SMZ|SCAMPTON}}
Resulting in:
