Fuel suppliers
No contract, no fuel. Your supplier decides what you pay per litre, how much arrives per day and how often a delivery fails to show up.

How fuel pricing works
Fuel has a market price that moves a little every week – at most 5 % per week, and never more than 15 % away from its base level. Your supplier adds a fixed markup per litre on top. You sell fuel to aircraft at a fixed price, so a cheaper supplier means more profit on every litre.
The supply chain starts in chapter 2; before that, fuel at your pump is unlimited. A grass-field start comes with a small contract with the village supplier already signed.
The suppliers
- Brenner & Söhne – the small country store from the village. Small quantities, no minimum purchase, free to sign and cancel at any time. Perfect for a grass field, too expensive for anything bigger.
- Nordtank Mineralöl – a regional wholesaler. The cheapest markup and large deliveries, but deliveries fail more often. Signing costs 5,000 €, cancelling 15,000 €.
- Aeropetrol Logistik – an aviation fuel specialist built for large airports. A little pricier, but very reliable. Signing costs 15,000 €, cancelling 50,000 €.
Minimum purchase
Wholesale contracts include a weekly minimum. If you take less, you pay a compensation fee for every litre short. Switch to a wholesaler only when your traffic actually burns that much fuel.
Failed deliveries
When a delivery fails, the next attempt follows a few hours later. A depot with enough stock rides it out easily; a nearly empty one may run dry – and then aircraft leave without fuel, you lose the sale and airlines get unhappy.
