Comparison

Looking for an AirlineSim alternative?

If you search for an airline management game today, most roads lead to AirlineSim. It has run for well over a decade, its traffic rights model is the deepest in the genre, and its player economy is a real economy. We built PlaneSim because we wanted more in some specific places. This page is an honest comparison rather than a sales pitch, written by the people who make one of the two games. Where AirlineSim is stronger, we say so.

Disclosure: we make PlaneSim. We have tried to describe AirlineSim as its own documentation and players describe it. Everything below is checkable, and the last section is about when to choose them instead of us.

The short answer

Pick AirlineSim if you want the mature product: a decade of refinement, the deepest regulatory model in the genre, and established multiplayer economies with real player-to-player trade.

Pick PlaneSim if a living world with AI competition, four-class cabins, slots held as ledgers, permanently archived seasons and a documented, deterministic engine matter more to you than maturity, and you can tolerate a beta. It is free while in beta, so trying both costs you an afternoon.

Who are you competing against?

AirlineSim's competition is entirely human. There is no scripted opposition: the market pressure on your routes comes from the playerbase, which is superb when a world is full and thin when it is not. The studio is straightforward about this being the design.

PlaneSim runs both. Human players compete alongside AI carriers built on five business models: regional, ultra low cost, low cost, legacy and leisure. The AI acts through the same journaled commands players use, so it cannot cheat. It takes the same loans, signs the same leases, and goes bankrupt through the same insolvency process you would. Its fare cuts and route entries are visible events on the map. A quiet world still fights back.

What happens to your history when a world ends?

AirlineSim worlds are long-running, and some short-term worlds carry fixed end dates. What survives a world's end is not something its documentation dwells on.

PlaneSim worlds run posted seasons, printed on the world tile from the first day. When a world closes it is sealed and published permanently: final standings, every carrier's record, readable by any signed-in account. The first world to complete its run is already on the archive. If you invest a season in an airline, the season outlives the server.

How deep is the operation?

Both games take operations seriously, with different centres of gravity.

AirlineSim's regulatory layer is its crown: airlines are national entities, traffic rights derive from real bilateral and multilateral frameworks, and outgrowing your home market is a genuine strategic problem. Its maintenance category system also puts a real, escalating cost on fleet fragmentation.

PlaneSim's centre of gravity is the schedule and the cabin. Slots are ledgers with named holders rather than capacity numbers. Connecting times are set per hub, split domestic and international. Cabins are geometric: every seat consumes floor area, and the frame holds fewer of them when you stretch the pitch. PlaneSim books four classes rather than the genre's usual three, with premium economy as a full cabin carrying its own demand. Traffic rights exist here too and gate route legality, but the incumbent's version of that layer is richer today.

Can you verify what the engine actually does?

AirlineSim publishes the structure of its systems and deliberately withholds the formulas. The handbook's own answer to a demand question is that you will have to try it and see. That is a legitimate design stance, and its community has spent years reverse engineering around it.

We took the opposite position. PlaneSim's engine is deterministic, every state change is journaled, worlds replay exactly, and the reference wiki is written from the engine's code rather than from marketing copy. When the demand model surprises you, the explanation is public.

What does it cost?

AirlineSim is pay to play through a credit system: roughly a two week free trial, then a per-world daily rate, with a firm and creditable no pay-to-win rule.

PlaneSim is free during beta. Paid game time is planned eventually and the same rule will hold: nothing purchasable will ever confer competitive advantage. We are saying this now, on the record, before any pricing exists.

When you should choose AirlineSim instead

Choose AirlineSim if the regulatory game is the part you want to play, because bilateral traffic rights are its deepest system and our version of that layer is younger. Choose it if you want a player-run economy with genuine trade between airlines, or if a decade of accumulated stability matters more to you than new systems. Choose it if a beta, and the possibility that things change under you, sounds like a bad time rather than an interesting one.

Trying PlaneSim

PlaneSim is a free browser airline management simulation game. There is nothing to download, worlds run around the clock whether or not you are signed in, and you can read the whole rulebook before you start. Worlds are open now at play.theplanesim.com, and the wiki will tell you what you are getting into first.
