PlaneSim
Persistent-world airline management · in the browser

Run the most realistic airline in the genre. In a world that fights back.

Found an airline, lease real airframes, and push schedules through real operational gates. Rivals, human and AI, are doing the same in shared worlds that keep running while you're away.

01 · the living world

The world doesn't wait for you.

AI carriers found routes, set fares, lease aircraft, take loans, sign partnerships, and go bankrupt, all through the same journaled commands players use. Five business models of rival. No cheating, no idling, and all of it watchable on a live interactive map.

Come back tomorrow and the world has moved: fares shifted, slots filled, a rival's network grown toward yours.

02 · operations

A schedule saves only when all seven gates pass.

Traffic rights, range, runway, slots, curfew, rotation feasibility, maintenance windows: checked live, before a single flight exists. Real slot ledgers. Per-hub minimum connecting times. No gate, no flight.

03 · commercial

Passengers who choose, not spawn.

A cast of customer types weighs your fare, timing, comfort, and connections against every alternative, including staying home. Class-aware across Y / W / C / F, and the per-option breakdown is on screen, not hidden in a formula.

04 · finance

Every cent is a ledger entry.

Categorized, time-stamped, and carrying the litres of fuel or the passenger count that priced it, then rolled up by category into statements you can drill all the way back down.

05 · the circular airframe economy

Every airframe has a history.

The used market lists real individual tails with open records: age, hours, cycles, condition, the heavy-check clock, and an appraisal, visible to every buyer. Lessors restock from a finite pool, bankrupt fleets recycle into estate sales, and in worlds with auctions, sealed bids decide who flies them next.

Your beaten-up ex-fleet can come back as a rival's bargain.

Why veterans stay

Built like an operations manual, not a mobile game.

These aren't marketing lines. They are how the engine is built, and the wiki documents every one of them.

Operations manualexcerpts
server truthEvery number on screen is computed by the engine. Missing data renders as a dash, never a guess.
fog of warYou see what a real airline would see. Rival fares and schedules are public; their loads and books are not.
determinismEvery state change is a journaled command. A world replays byte-identically from its journal.
persistenceWorlds are never wiped. New features never silently change a running economy.
Learn it in place

27 reference articles, written from the engine's code.

How booking, fog, leasing, and the ledger actually work, including an honest list of what the engine won't tell you. Deep-linked from every screen where a system bites.
