Flying to Nairobi
Jomo Kenyatta International Airport (NBO / HKJK) · Last reviewed: April 2026
Airport Overview
Jomo Kenyatta International Airport (IATA: NBO, ICAO: HKJK) is Kenya's largest airport and the primary international gateway for East Africa. Located approximately 18 km southeast of Nairobi's city center, the airport operates within the Nairobi FIR (HKNA), managed by the Kenya Civil Aviation Authority (KCAA).
According to IATA traffic data, NBO handles approximately 8 million passengers annually and serves as the hub for Kenya Airways. The airport has two runways (06/24, 4,117 m and 14/32, currently limited operations). Terminal infrastructure includes Terminal 1 for international flights and Terminal 2 for domestic services. Elevation at 1,624 m (5,327 ft) AMSL affects aircraft performance calculations, particularly during hot-season operations.
KCAA has implemented performance-based navigation (PBN) procedures at NBO, as documented in ICAO regional implementation reports. ATC radar coverage is concentrated around the Nairobi terminal area, with procedural control applied in certain outer sectors of the HKNA FIR.
Common Routes & FIRs Crossed
Flights to Nairobi transit several FIRs depending on origin. According to Eurocontrol and published airline routing data, common paths include:
From Europe: Traditionally routed via Egypt (HECC) and Sudan (HSSS) FIRs, then south through Ethiopian (HAAA) or Somali (HCSM) airspace into HKNA. Following Red Sea area disruptions, Eurocontrol data indicates some operators have adopted longer western routings via Chad (FTTC) and Central African FIRs.
From the Gulf: Routes cross the Arabian Peninsula and Somali FIR (HCSM) or route via HAAA (Addis Ababa) before entering HKNA from the north. Some operators route further south via the Indian Ocean to avoid Somali airspace.
From Asia: Flights from India and Southeast Asia typically route over the Indian Ocean, entering HKNA from the east. This routing avoids the complexity of overflying multiple restricted FIRs in the Middle East.
According to published IATA route analysis, disruptions in the Red Sea corridor and Somali airspace have increased average flight times for some Europe-Nairobi routes by 30-90 minutes, depending on operator routing decisions.
Airspace Conditions
The HKNA FIR itself operates without standing EASA or FAA restrictions, according to published advisory databases. However, the FIR borders the HCSM (Mogadishu/Somalia) FIR to the east, which has been subject to various international advisories. ICAO documentation notes that the proximity to restricted Somali airspace affects traffic management in the eastern sectors of HKNA.
According to KCAA publications, radar coverage and ATC communication quality in the northeastern sector of the FIR, near the Somali border, is reduced compared to the Nairobi terminal area. Procedural separation is applied in these areas, which can limit traffic flow during peak periods.
ICAO regional reports document that rerouting of traffic from neighboring restricted FIRs (Sudan, Somalia, Yemen) has increased overflight volume through Kenyan airspace. KCAA has reported capacity investments in response, including new surveillance equipment and controller training programs, though implementation timelines extend into 2027.
