Worlds can include computer-run airlines. They are real competitors (founding routes, setting fares, leasing metal, taking loans, signing partnerships), and they are the reason a market never sits still.
Same rules, no cheating#
AI carriers issue the same commands you do, through the same validation: same starting capital, same aircraft market, same slot pools, same curfews, same fare rules, same books. They earn or lose money exactly as you would, and if the money runs out they go bankrupt through the same insolvency process: schedule wound down, fleet liquidated, estate recycled into the market like any player's; see Bankruptcy & estates. Difficulty settings change how often and how shrewdly they act, never the rules they play under.
Five business models#
Every AI carrier runs one of five archetypes, and you can read its strategy from its behavior:
| Archetype | What to expect |
|---|---|
| Regional | Small metal; it only enters markets nobody serves, but defends the ones it holds |
| Ultra-low-cost | Deep fare undercutting, dense single-type fleet, big markets, no partnerships ever |
| Low-cost | Mild undercutting on mid-size markets at primary airports |
| Legacy | Premium fares, fortress hub, big fleet, patient, and the keenest partner |
| Leisure | Discount fares, longer legs, flies mainly Thursday through Sunday |
Each carrier also has a name, a CEO, and a public agenda, visible on its airline card in the Directory, so you can tell who you're up against.
What they actually do#
AI carriers plan every few game days. They read their own accounts first: a profitable carrier grows, a struggling one cuts its worst routes, returns idle leased aircraft, and can even relocate its hub. When you enter their markets, expect a response: fare matching, extra frequencies, and an eventual retreat if you win the traffic. They lease, buy used, and place factory orders; take and repay loans; hold reserve aircraft; run route marketing campaigns; and sell off worn airframes.
A carrier that outgrows its home opens a second base. When its hub can no longer absorb another aircraft but the carrier is still healthy, it picks the best-connected destination it already serves, ferries idle metal there, and starts building that station's own bank of departures. It also buys on cost per seat rather than size alone, so it right-sizes its metal to the sectors it actually flies instead of parking a widebody on a two-hour hop.
They also participate in the partner economy on their own terms: regionals and low-cost carriers accept interline and codeshare deals, legacies court feeders and join alliances, ultra-low-cost carriers refuse everything. See Interlining and Codeshares.
Consolidation: mergers and takeovers#
In worlds where absorption is enabled, carriers can buy each other outright. A thriving carrier will move on a weaker overlapping rival: a takeover rescues a carrier that has run out of cash before it liquidates, and a merger folds a carrier that has been losing money for weeks into the stronger network. Either way the whole airline changes hands at once: its fleet, routes, leases, loans, airport slots and cash all pass to the acquirer, and the absorbed airline is retired.
It takes two to merge: the buyer makes an offer, and the target has to accept it. A struggling AI will take a fair offer rather than fly itself into bankruptcy; a healthy one stays independent. The acquirer assumes the target's debts, so it only bids when it can carry them. You can be either side of this (absorb a distressed rival, or accept an offer for your own airline), and every offer and completed merger shows up in world news.
How you see it#
AI moves surface as world news: routes opened and closed, fleets expanded, fare wars started and ended, hubs moved, deals signed, new carriers entering. Their flights, fares, and schedules appear in every market view exactly like a player airline's. When an AI carrier collapses, a fresh entrant can later be founded to fill the gap, so the cast refreshes over the life of a world.
Per-world setup#
AI is a world setting: it is off by default, and there is no ceiling on the roster: a world can carry as many computer-run carriers as its operator chooses to spawn, at easy, normal, or hard difficulty. Check your world's roster in the Directory; see World config basics.
