STN City Code: London IATA Airports

STN identifies the city of London, United Kingdom, in IATA coding. Airport codes in this dataset for that city: STN. A city code is not always the same as an airport code.

Overview

STN is the IATA city code stored for London, United Kingdom (GB). City codes group one or more airports. In this dataset STN is aligned with airport STN. Some cities share the airport code; others (NYC, LON, TYO) do not. Airport names stored: STN London Stansted Airport. GDS availability and some pricing entries use the city code when the traveller can use any airport in the metro. Ticketed segments still print a specific airport such as JFK rather than NYC. This page does not list every airfield in the metropolitan area, only rows in the catalog. Timezone and ICAO live on each airport page.

How to use this page

  1. Search STN or London in the city code finder.
  2. Open each airport page for ICAO and timezone.
  3. Parse the actual PNR to see which airport was ticketed.

Example

Example: a PNR city pair may use STN as the airport. If a host screen shows city STN, confirm it matches this metro before quoting.
