How Airlines Die

Nothing in PlaneSim stops you spending into the red except the insolvency clock. What the countdown measures, what liquidation actually does, and why the network dies while the metal survives.

No one calls in a loan in PlaneSim. There is no creditor meeting, no bailiff at the hangar door. The game lets you spend into the red without protest from the bank, the lessor or the payroll, and that permissiveness is the trap. The only enforcement mechanism is a clock, and the clock is patient.

The insolvency clock

The moment your cash goes negative, it starts. A warning fires on day one, and every further day of continuous negative cash counts up. Climb back above zero, even briefly, and the clock fully resets; there is no memory of past scares. Stay under for the world's grace period, by default 14 days (your world may differ), and liquidation runs automatically. No hearing, no negotiation.

You are given two early-warning instruments and should use both. The cash-runway ratio in your financial rating tells you how long the current picture can hold. The Upcoming Events calendar is sharper: it lines up the scheduled debits ahead of you, lease rent, loan payments, deliveries, with a coverage marker showing how far today's cash actually reaches through them. An airline that reads that marker weekly does not get ambushed.

The wind-up

Liquidation is thorough and immediate.

• Every flight number is deactivated and every future flight cancelled, with no passenger compensation. The estate has no money to pay it.
• Leases are terminated and deposits refunded to the estate; leased tails go home to their owners.
• Outstanding loans are marked defaulted.
• In slot-ledger worlds, every slot holding returns to the airport pools.
• Owned airframes are sold off, by estate auction or fire sale depending on how the world is configured.

The airline itself remains in the world as a bankrupt tombstone, and you are returned to the world page. A dead cockpit cannot be flown.

No second act, usually

There is no restructuring. No debt workout, no refinancing at the eleventh hour, no equivalent of Chapter 11. Prevention is the whole game, and the design is honest about it.

The one exception is worlds that enable absorption. There, a solvent carrier may buy a rival as a going concern, or rescue an insolvent one before liquidation runs. Whether your world allows it is visible under World → Configuration; on most worlds the answer is no, and the clock is the last word.

The network dies, the metal does not

Notice what liquidation destroys and what it merely relocates. The network is gone completely: flight numbers deactivated, slot holdings surrendered to the pools, the schedule erased. Routes are not assets in this game; they are arrangements, and they die with the operator. Nobody inherits your city pairs, though at congested stations the slots you hand back are suddenly there for the taking.

The fleet is a different story. Every airframe survives. Leased tails return to their lessors carrying the hours and cycles you put on them. Owned tails re-enter the used market through the estate process, sold under distressed terms, which is why bankruptcies are where the sharpest deals in the used market come from. The buying side of that trade has enough moving parts that we cover it separately; the short version is that one airline's end is priced into another airline's fleet plan within days.

Staying off the block

Airlines here rarely die of one bad decision. They die of fixed weekly outflows agreed to in better times: the loan annuity that draws itself, the lease rent that bills itself, both indifferent to whether this week's flights earned anything. The clock only measures the gap between those commitments and your cash, and it measures nothing else.

Keeping it silent is mostly discipline about what you sign. Before committing to anything with a weekly debit attached, the two reference articles worth internalizing are the wiki's Loans & leverage and Lease obligations. Both fixed outflows are survivable on their own. The airlines on the tombstone list are the ones that stacked them faster than the network could close its booking curves, then discovered the bank does not pause payments and the grace period is shorter than a turnaround plan.
