Frankfurt-Hahn Airport

Frankfurt-Hahn Airport carries the IATA code HHN — the three letters printed on boarding passes and baggage tags — and the ICAO code EDFH, used in flight plans and by air traffic control. It serves Frankfurt am Main (Lautzenhausen), Germany.

IATA codes are assigned by the International Air Transport Association for passenger-facing use; the four-letter ICAO code encodes region and country and belongs to the operational side of aviation.
