What happens when your entire strategy depends on one client?

Charleroi Airport in Belgium is learning the hard way.

The city just increased taxes by €3 to €5 per passenger.
Now Ryanair — the airport’s dominant airline — is threatening to remove 5 of its 18 aircraft based there.

That’s not just a schedule change.
That’s a strategic shock.

When one airline brings a huge share of your traffic, your business model depends on them.
If they reduce flights, passenger numbers drop.
Shops, parking, and airport revenue drop too.

This is the risk of relying too heavily on a single key client.

So what should the airport do?

✈️ Give Ryanair a discount?
🏛️ Push the city to lower taxes?
📞 Bring in other airlines to diversify?
🤔 Or rethink its whole strategy?
