The Kenya Airports Authority, commonly abbreviated as KAA, is the state corporation responsible for managing and developing Kenya's public airports. Its portfolio includes Jomo Kenyatta International Airport (JKIA) in Nairobi, Moi International Airport in Mombasa, Eldoret International Airport, Kisumu International Airport, Wilson Airport, and several other airports and airstrips across the country. JKIA, as the country's primary gateway and a major regional hub, generates the largest share of passenger traffic and, with it, the largest share of public notices.
Because KAA controls the physical infrastructure — runways, terminals, aprons, parking, and passenger facilities — it is the authority best placed to tell travellers when something at an airport will work differently than usual. That is where advisories come in.
What an Airport Advisory Actually Is
An airport advisory is an official notice issued to inform passengers, airlines, and other airport users about a change in normal operations. It is informational in nature. It does not automatically mean an airport is closed or dangerous. In most cases, it means: something is changing, here are the details, and here is what you should do about it.
Advisories typically cover practical details such as:
- The airport and specific facility affected (for example, Runway 06/24 at JKIA, or Terminal 1A departures)
- The date and time window during which the change applies
- The nature of the change — a closure, reduced capacity, a temporary procedure, or a safety precaution
- Guidance for passengers, such as arriving earlier, using an alternative entrance, or confirming flight status with the airline
Some advisories are planned weeks in advance, such as scheduled runway maintenance. Others are issued at short notice in response to weather, technical faults, or unexpected events.
Common Reasons KAA Issues Advisories
Understanding the typical triggers behind an advisory helps you judge how seriously to take one and how it might affect your plans.
Runway and facility maintenance. Runways, taxiways, and terminal systems need periodic repair and rehabilitation. When major works take place at a busy airport like JKIA, operations may be limited to certain hours or shifted to secondary runways. These are usually announced in advance through official advisories, and airlines adjust schedules accordingly. Travellers are normally advised to expect delays, reconfirm flights, and allow extra time.
Weather. Kenya's rainy seasons — generally the long rains around March to May and the short rains around October to December — can bring heavy downpours, reduced visibility, and thunderstorms that disrupt flight schedules. Fog occasionally affects early-morning operations in Nairobi. Weather advisories usually caution passengers about possible delays or diversions rather than cancellations, but the knock-on effects on a busy hub can last most of a day.
Security and access changes. Temporary changes to airport access, parking, or terminal entry sometimes occur around high-profile visits, large public events, or security operations. Advisories in these cases typically focus on which entrances to use, where to park, and how much extra time to budget.
Technical and system interruptions. Check-in systems, baggage handling, lighting, or power supply can experience faults. When this happens, KAA may issue a notice confirming the situation and the steps being taken, while airlines handle rebooking and passenger communication.
Health and regulatory requirements. During public health situations, advisories have been used to communicate screening procedures, documentation requirements, and changes to terminal processes. Similar notices may appear when new entry or transit requirements are introduced.
Where to Find Official Advisories
This is the part that matters most. During any disruption, unofficial information spreads faster than verified information, and travellers who rely on rumour often make poor decisions. Official KAA advisories are published through a small number of channels:
- The KAA official website (kaa.go.ke), where notices and press releases are posted, often under a news, media, or advisories section
- Official social media accounts operated by KAA and by individual airports such as JKIA, which post real-time updates during operational changes
- Airport information desks and public announcement systems for travellers already at the airport
- Airlines and travel agents, who receive operational updates directly and pass them on to affected passengers through SMS, email, or app notifications
A useful habit is to identify the official handles and website for your specific airport before you travel, so that during a disruption you know exactly where to look instead of scrolling through unverified claims.
Advisories and NOTAMs: Not the Same Thing
Travellers sometimes confuse public advisories with NOTAMs — Notices to Airmen. A NOTAM is a formal message issued through the international aeronautical information system and directed primarily at pilots, airlines, and air traffic personnel. It covers matters like runway closures, navigation aid outages, and airspace restrictions, using standardised codes and technical language.
A KAA public advisory, by contrast, is written for passengers and the general public. The two often describe the same underlying event — a runway maintenance programme, for instance, will generate both a NOTAM for flight crews and a public advisory for travellers. If you are a passenger, the public advisory is what concerns you; the airline reads the NOTAM and adjusts the schedule on your behalf.
What to Do When an Advisory Affects Your Flight
Receiving or reading an advisory is only useful if you respond correctly. The steps below cover most situations:
- Read the details carefully. Note the exact airport, dates, and hours affected. An advisory about overnight runway works, for example, may not affect a midday flight at all.
- Contact your airline before heading to the airport. Airlines hold the authoritative status of your specific flight. If an advisory has forced schedule changes, the airline will confirm your new departure time or rebooking options.
- Arrive earlier than usual when advised. When capacity is reduced or procedures change, check-in, security, and boarding all slow down. The standard advice in most advisories — arrive at least three hours before international departures — becomes even more important.
- Build buffer time into connections. If you are transiting through JKIA or connecting between Wilson and JKIA for a domestic leg, leave generous margins during any advisory period. Tight connections are the first casualty of operational disruptions.
- Keep your booking reference and documents accessible. Rebooking queues move faster when your reference number, identification, and travel documents are ready.
- Monitor official channels until you depart. Situations evolve. An advisory issued in the morning may be updated by afternoon, and following the official accounts ensures you hear about changes first.
Avoiding Misinformation
During disruptions, screenshots of old advisories circulate widely, and fabricated notices occasionally appear on social media. Protect yourself with a few simple checks. Confirm that the notice comes from a verified official account or the KAA website itself. Check the date on any shared advisory — a runway works notice from two years ago has no bearing on your flight today. And when in doubt, call your airline: they will never route your rebooking through informal channels, and any message asking you to pay rebooking fees through personal mobile transfers to an individual should be treated as a scam attempt.
Practical Habits for Travellers
Beyond responding to individual advisories, a few habits make travel through Kenyan airports smoother year-round. Check your flight status the night before and again on the morning of travel. Follow your departure airport's official social media account, particularly if you travel frequently. During the rainy seasons, pad your schedule rather than cutting it fine. If you are meeting arriving passengers, ask them to message you after landing rather than timing your drive to the scheduled arrival, since advisories and delays can shift timings significantly.
The Bottom Line
A KAA airport advisory is not bad news by definition — it is the system working as intended, giving you advance warning so you can adjust. The travellers who navigate disruptions best are those who read the actual notice, verify it through official channels, speak to their airline early, and give themselves extra time. Kenya's airports handle millions of passengers a year across a network that stretches from the coast to the border regions, and the advisory system exists precisely to keep that network predictable. Treat every advisory as useful intelligence rather than an inconvenience, and you will almost always arrive calmer, better prepared, and on time.
