HEL City Code: Helsinki IATA Airports
HEL identifies the city of Helsinki, Finland, in IATA coding. Airport codes in this dataset for that city: HEL. A city code is not always the same as an airport code.
Overview
HEL is the IATA city code stored for Helsinki, Finland (FI). City codes group one or more airports. In this dataset HEL is aligned with airport HEL. Some cities share the airport code; others (NYC, LON, TYO) do not. Airport names stored: HEL Helsinki 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
- Search HEL or Helsinki in the city code finder.
- Open each airport page for ICAO and timezone.
- Parse the actual PNR to see which airport was ticketed.
Example
Example: a PNR city pair may use HEL as the airport. If a host screen shows city HEL, confirm it matches this metro before quoting.
