Jomo Kenyatta International Airport

Jomo Kenyatta International Airport carries the IATA code NBO — the three letters printed on boarding passes and baggage tags — and the ICAO code HKJK, used in flight plans and by air traffic control. It serves Nairobi, Kenya.

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.
