1/3 The Hidden Cost of an ATC "Go-Slow" let me try to break it down for you and i hope this lands on the desk of decision makers. When Nairobi hub Coughs, Kenya Airways Catches Pneumonia Every time our air traffic controllers threaten industrial action, the public picture is always the same exhausted travellers sitting on their suitcases at Jomo Kenyata International Airport (JKIA), staring at departure boards full of delays. That image, as painful as it is, is only the tip of the iceberg. The real damage happens quietly, thousands of kilometres away, in the operations rooms of airlines in London, Amsterdam, Dubai and Doha, long before any of those planes even leave the ground and nobody pays a heavier price for this than our own national carrier, Kenya Airways. So what Exactly Is a "Go-Slow"? Most people assume a strike means workers walk out and the airspace shuts down. A go-slow is far more subtle, and in some ways more damaging. Nobody walks off the job instead, air traffic controllers follow every single safety rule and regulation to the absolute letter, with none of the normal flexibility and judgement that keeps traffic moving efficiently. In ordinary operations, controllers use experience and confidence to compress the gaps between landing and departing aircraft, while still keeping everyone safe. During a go-slow, that flexibility disappears controllers double the spacing between arriving planes, take the maximum allowed time to issue every clearance, and stop using the shortcuts that keep traffic flowing. If JKIA can normally handle 20 arrivals an hour, a go-slow can quietly strangle that down to five. Aircraft end up circling for hours in holding patterns, or sitting on the tarmac waiting endlessly for a departure clearance. Why airlines cancel flights before they even take off. This is the part most Kenyans never see, a foreign airline does not need to wait until its plane is stuck over Nairobi to feel the pain of a go-slow. The moment global flight-tracking systems show that JKIA's acceptance rate for incoming aircraft has slowed down, alarm bells go off at airline headquarters on the other side of the world. Three things make this an unacceptable risk for any serious carrier: ✅️1. Fuel and diversions. A pilot cannot simply hope for the best. If Nairobi is delaying arrivals, an inbound aircraft will burn through its reserve holding fuel while circling. Once it hits its minimum safe fuel level, it has no choice but to divert, often to Mombasa or Kilimanjaro. That single decision triggers unscheduled landing fees, emergency hotel bookings for hundreds of passengers, and total chaos across the airline's onward network. ✅️2. Crew running out of legal hours. Pilots and cabin crew operate under strict legal limits on how long they can stay on duty. If a flight is stuck waiting for a landing slot, or held on the ground at its point of origin because Nairobi cannot guarantee it a slot, the crew can simply "time out." Once that legal limit is hit, they are not permitted to fly, full stop, and there is rarely a spare crew sitting nearby to take over a multi-million-dollar aircraft in a foreign country. ✅️3. A grounded aircraft earns nothing. Long-haul aircraft are built to keep moving. A plane flying Amsterdam to Nairobi is usually scheduled to turn around and fly straight back within a few hours. If a go-slow traps that aircraft on the ground in Nairobi for six hours, it misses its return flight entirely. That single missed rotation then cascades into cancelled or delayed flights across the airline's entire global network, often affecting routes that have nothing to do with East Africa at all. Faced with the choice between risking a $200 million aircraft in an unpredictable operational environment or simply cancelling the Nairobi flight altogether, foreign airlines almost always choose the second option. The painful part cancellation happens at the destination's expense, not theirs.
