Competition & Alliances: Winning Contested Markets

You are never alone on the map. Tailwinds' AI airlines grow, defend their hubs, and move into your profitable markets. This guide covers how they behave, how to fight back without a fare war, what alliances actually buy you, and when to simply buy the competition.

How AI competitors think

The AI carriers in Tailwinds run their own airlines — they operate hubs, deploy fleets bought with their own cash, sell connections over their hubs, and look for profitable opportunities, including yours. Each one has a personality, shown on the Competition tab: Aggressive carriers attack busy routes others already fly, Copycats follow proven markets (especially yours), Fortress carriers build density at home and defend it, Niche carriers avoid crowded lanes, and Expansionist and Balanced carriers grow where the money is. The bigger your airline gets, the more attention they pay you. Four behaviours are worth internalising:

• Success is a signal. The game models encroachment: a route running high loads at fares well above the market reference is an advertisement, and a route flying essentially full draws entrants even at fair fares. An entrant prices under you and builds up frequency over several weeks. The most contested markets in your network will be your best ones — that's by design.
• They defend their own turf. On shared routes that make them money, rivals add flights to match your schedule, and they nudge fares down when you undercut them. Fortress carriers defend their hub markets hardest. The cost of attacking a fortress hub is usually paid in margin, for years.
• They can be provoked. Undercut an aggressive or fortress carrier, or fly into a fortress carrier's hub, and it may declare a fare war on that route: fares slashed below cost, on purpose, for several weeks. It ends with a truce, when the rival can no longer afford it, or when you leave the route.
• They notice you as you grow. A small start-up is barely on the AI's radar. As your airline's value climbs, rivals pay steadily more attention: they look harder at your routes when choosing where to expand, defend more readily against you, and become more willing to start a fare war. The attention builds gradually with your size rather than arriving all at once, and it is at its fullest for an airline worth a quarter of a billion or more.
• They live through the same world you do. A recession, a pandemic scare or a fuel spike hits the AI carriers' books as hard as yours. Their loads thin, their profits shrink and the weaker ones trim service, so a downturn is also a chance to take ground from a rival that is hurting.
• They back off, but rarely leave. Make a route unattractive — keep its fares just under the market reference for around twenty weeks — and an entrant eventually stops actively contesting it. It doesn't disappear: it stays on with a smaller schedule and only a mild undercut, and comes back hard if you let the route get fat again. Network carriers do withdraw from routes that keep losing them money, and trim ones that fly empty.

The field also changes on its own. Rivals open second hubs, invest in their product when they're profitable and cut service when they're not, merge with each other, fall into a fire sale and go bankrupt, and new start-ups appear mid-game. The News tab keeps the record.

Choosing your rivals

By default a new game draws about 25 rivals from the game's own roster, different every time. The Rivals options on the setup screen let you set the field yourself:

• How many, and how hard they push. Choose a field of 10, 25 or 40 random rivals. Rival pressure sets how closely they watch you: relaxed rivals pay you half the usual attention and make their moves less often, while fierce ones notice you early, fight harder for your routes and move more often.
• Custom set. Paste a rival set: a short block of text listing each airline's name, home airport code and tier (budget, legacy or premium), and optionally its size (small, medium or large), founding and closing years, logo, personality and quality. Size sets a rival's starting cash and network; its market value then comes out of how it plays. You can play with only your set or add it to the random field, and a set can start with up to 60 rivals.
• Fleets, routes and second hubs. A rival in a set can list the aircraft it flies (or just its manufacturers), its starting routes and a second hub. Name one manufacturer as "maker": "Boeing", or several as a list: "maker": ["Boeing", "Embraer"]. One piece of text with commas, "Boeing, Embraer", works too. Writing "maker" twice doesn't, because only the last copy of a repeated name is read. A carrier with a fleet preference only buys what it prefers when one of those types can fly the route, and takes whatever fits when none can. Within its preference it still picks the best-sized aircraft for each route, so a carrier allowed two makers may end up flying mostly one. A listed route no aircraft of the era can fly is left out at the start.
• Founded and closed in their own years. In an era game, a rival founded after your start year doesn't exist yet. It appears once the calendar reaches its year, with its own starter network, if the field has room; otherwise it waits and tries again. A rival with a closing year ceases operations in that year, and one already closed by your start year never appears. Classic games have no calendar, so every rival in a set starts on day one and stays.
• Random logos and a chance to appear. Any rival's logo can be "random", and "randomLogos": true at the top of a set shuffles them all; random logos are spread across the whole range, so a big set doesn't end up with ten of the same one. A rival can also have a "chance" from 0 to 100: the percent chance it takes part in a game at all, so a long list of airlines plays out differently every time. The roll leans toward underserved markets: a rival is likelier to appear where few airlines are based near its hub and less likely where many are, so a chance of 50 might come in three times in four in an empty region and one time in four in crowded Europe. Add "crowding": false to keep the percentage exact, and put "chance" at the top of a set to give every rival without its own the same odds. A rival founded later rolls in its founding year; one that misses never appears that game. A set made only of chance rivals always gets at least one.
• No rival based at my hub. Removes any rival based at your home airport from the starting field. Others still fly in, and airlines founded later may still choose to base there.
• New airlines and mergers. Random start-ups can be none, rare, normal or frequent; with none and a custom set, only the set's own airlines ever join, so the game plays exactly as written. You can also stop rivals merging with each other (you can still buy them).
• Sharing. The Competition tab can copy any game's rivals as a set, including the airlines your set has still to found, so you can share a field with friends or replay it.

Manufacturer names

Write a maker the way the aircraft market spells it; capital letters don't matter. A name also matches every maker whose name contains it: "Douglas" covers McDonnell Douglas as well, "de Havilland" covers De Havilland Canada, and "Airbus" includes the Airbus/CASA turboprop. A misspelt maker is left out with a warning on the setup screen, and the rest of the list still counts.

In an era game a maker only matters once one of its aircraft is on the market: a rival limited to Airbus in a 1960 game flies whatever fits until Airbus's first type enters service. The table gives, for each maker, the year its first type in the game entered service and the year its last production line closed.

Reading a contested route

When a competitor shows up on your route, demand doesn't just halve. The market splits based on fares, frequency, product quality, connections, brand awareness and reputation, and loyalty — and a rival's one-stop over its own hub competes with your nonstop too. The head-to-head card for each contested route on the Competition tab shows each carrier's projected share and flags what's costing you, such as a brand most travellers haven't heard of yet, or an all-economy cabin against a rival that sells business. Before reacting, work out which lever they're actually beating you on. Cheaper fares? More frequencies? A better cabin? Each calls for a different response, and the reflexive response — matching their fare cut — is usually the worst available.

Defending without a fare war

Fare wars destroy both airlines' margins and mostly benefit passengers — and undercutting the wrong carrier is how they start. You have better weapons:

• Frequency. More weekly departures win you a bigger share of the pair, though each extra flight adds a little less than the one before. Two smaller aircraft usually beat one big one on a contested route — same seats, twice the schedule presence.
• Product quality. Cabin configuration and catering feed the quality score that shifts demand share at equal fares. Quality costs pennies per passenger compared to a fare cut. The demand & quality guide breaks down every point of the score.
• Loyalty. A loyalty program makes your passengers sticky — repeat customers choose you even when the competitor undercuts slightly. Loyalty compounds over time and is strongest at your hub, which is precisely where you'll be attacked.
• Reputation. Your airline-wide reputation acts as a multiplier across every contested market. Reliability and consistent product quality build it slowly; it pays out everywhere at once.
• Selective retreat. Not every route deserves defence. If a market was marginal before the competitor arrived, redeploy the aircraft to a better one and let them have the scraps. See diagnosing a losing route.

Alliances: what they're for

Tailwinds has five global alliances — SkyBridge Alliance, Pacific Pact, Apex Network, Horizon Coalition and Meridian Alliance — each made up of AI carriers. You can belong to one at a time. Each sets an entry bar on the Alliances tab: a minimum number of routes, a minimum average quality score, and for most blocs a carrier type, judged from your average quality (Apex takes premium carriers only; Horizon Coalition, the low-cost bloc, takes anyone). Joining costs an initiation fee plus weekly dues; leaving is free. In a game that starts in a historical year, no alliance exists until 1997, when the founding members form the five blocs. Here's what membership buys:

• Network extension. Partner networks carry your connecting passengers to places you don't fly. Your hub effectively grows spokes you never paid for, and their passengers feed your trunks in return — though feed only boards seats your own passengers left empty, so a full flight carries none. The Alliances tab shows which airports your partners reach that you don't.
• A lift where partners fly. On routes where an alliance partner also flies the pair, your offer gets a revenue lift of a few percent, varying by bloc.
• Scale you haven't built yet. For a mid-size airline, an alliance is a shortcut to global relevance — you offer worldwide connectivity years before your own metal could.

The trade-offs are real too: the dues run every week whether or not the feed shows up, and membership doesn't stop a partner flying against you — the Alliances tab lists where they do. Blocs also change around you: healthy independents join, and members that fall into a fire sale get expelled. Join when your network has something to gain from reach; stay independent while your value is still concentrated in one region you can dominate alone.

Codeshares

Codeshares are the à la carte version: a bilateral agreement with any AI carrier, in an alliance or not, for a weekly fee that rises with the partner's tier. There's no limit on how many you sign, and they deliver the same kind of connecting feed with the partners you choose. In historical-start games they arrive in 1990.

Buying a rival

The final answer to a competitor is to own it. Any AI airline can be acquired from the Competition tab: the price is set off its market value plus a takeover premium, never less than roughly what its cash and fleet are worth, and a carrier in a fire sale is discounted (though never below that floor). You take over its aircraft, routes, gates, crews and cash in one move. A takeover is expensive and adds every aircraft type the rival flew to your fleet, so check the fit before you sign.

A simple doctrine

1. Fortify the hub. Frequency, quality, and loyalty at home before adventures abroad.
2. Pick fights you can win. Attack underserved markets and weak competitors, not fortress hubs.
3. Defend with product, not price. Fare cuts are the last resort, not the first.
4. Know your expendables. Decide in advance which routes you'd walk away from — it makes the decision easy when the time comes.
5. Use alliances deliberately. They're a network strategy, not a badge.
