The airport

IATA code: ORY
ICAO code: LFPO
Airport: Orly Airport
City: Paris, France
Code origin: Documented

Orly was Paris's main airport until Charles de Gaulle opened, and remains the busier of the two for domestic flights. It has a strict night curfew, which is one reason long-haul carriers moved north.

The other code, LFPO

Every airport has two codes. The three-letter IATA code, ORY, is the one on your boarding pass and your luggage tag, and it is assigned for commercial use. The four-letter ICAO code, LFPO, is the one pilots and controllers use, and it is assigned geographically: the first letter or two identify the region, so every airport in the same part of the world shares a prefix. That is why LFPO looks nothing like ORY.
