Hub Strategy: Building Networks That Feed Themselves

Your hub choice shapes everything that follows — which routes are viable, which aircraft make sense, and how hard the competition hits back. This guide covers picking a first hub, growing it, and knowing when a second one is worth the money.

Why hubs matter more than routes

A route in isolation earns whatever its two endpoints can generate between them. A route plugged into a hub earns that plus every connecting passenger flowing through it. That's the whole hub-and-spoke idea: ten spokes into one hub don't create ten markets, they create closer to fifty-five, because every spoke can exchange passengers with every other spoke through your hub. In Tailwinds, connecting traffic is often the difference between a marginal spoke and a solidly profitable one — a thin route that could never survive on local demand alone becomes viable when it also feeds your long-haul departures.

Choosing your first hub

Airports in Tailwinds come in three tiers — mega, major, and regional. Major and regional are set from each airport's real passenger traffic; mega is reserved for the world's biggest hubs. The tier sets gate rent, landing fees and fuel prices, and the mega and major airports are where rival airlines build their networks. It does not set demand — that comes from the city. Bigger sounds better, but the best first hub is usually not the biggest one available. Wherever you found your airline becomes your first Hub, and its country becomes your home country. Look for four things:

• Strong local demand. Metro population drives the demand model. You want a real city behind your hub so your routes earn even before connections kick in. Some airports also punch above their population because they're tourism magnets or a country's primary international gateway — the game models both. A city with several airports is one market: London's airports share London's passengers, with the secondary fields drawing a smaller slice.
• Geography that supports spokes. Count the cities within roughly 500–1,500 km. That ring is where your first narrow-body and turboprop routes will live. A hub in the middle of a dense region beats a bigger airport on the edge of nowhere.
• Room to grow. At mega-hubs you'll fight established AI carriers from day one. A busy major-tier airport with lighter competition frequently earns more, sooner, with less drama.
• A believable long-haul future. Eventually your hub will host intercontinental routes. A hub that can one day fill a widebody to another continent is worth a small compromise today.

Hub tiers: what you build at the hub

Your own connecting itineraries are only sold through airports designated on the Hubs screen, and the designation comes in four steps. Each needs more gates and routes, costs more to build and to run every week, and pays you back with more attractive connections, more connecting seats and a bigger quality bonus on its routes:

• Focus City — 5 gates and $1M. The only tier you can open outside your home country, and only one per foreign country.
• Hub — 10 gates, 4 routes at the airport and $5M. Full hubs must be in your home country.
• Major Hub — 15 gates, 20 routes, 2 international destinations and $25M. From here your own line maintenance discounts the aircraft that fly through.
• International Gateway — 20 gates, 50 routes, 6 international destinations, $100M, half a year as a Major Hub and 1,000 connecting passengers a week.

Designated stations also make your flying cheaper there: ground handling and catering cost less, and crew layovers cost much less, with the discounts growing at each tier. Gates set hard limits too: each gate you lease covers 50 weekly departures at that airport, and a route can't add frequency beyond what your gates at both ends allow. At a designated hub they matter a second way. Each tier handles a set number of weekly departures per gate, always fewer than 50. Run more flights than your gates can handle and the hub loses some of its connecting traffic until you buy more gates or trim frequency. Your local passengers are not affected.

Growing the hub: rings and spokes

Once the hub is chosen, growth follows a rhythm:

1. Ring one — short spokes. Open 3–6 routes to nearby cities with regional jets or turboprops. These prove demand, generate steady cash, and start building the feed pool. The turboprop guide covers the cheapest aircraft to do this with.
2. Ring two — medium haul. Add narrow-body routes to bigger cities 1,500–4,000 km out. Each new spoke makes every existing spoke slightly more valuable through connections.
3. Trunk routes. When feed is deep enough, open long-haul with a widebody. This is where hub economics pay off: the widebody fills with a blend of local demand and connecting passengers your spokes have been accumulating.

Watch each spoke's load factor as the network grows. A spoke that was marginal at five network destinations often climbs steadily as you add more, because it's carrying an increasing share of connecting traffic. Give new spokes time to mature before judging them — a new route takes about 16 weeks to reach its full demand.

Defending the hub

Success attracts attention. Tailwinds' AI competitors notice profitable markets and move in — the game models route encroachment directly. Your hub is the one place you should never cede ground:

• Frequency beats size defensively. Three daily narrow-body flights are harder for a competitor to displace than one widebody flight, because passengers weigh the number of departures, not just the seat count.
• Reputation and loyalty compound at hubs. Cabin quality, catering, and a loyalty program all shift share on contested routes. Passengers with your loyalty status pick you at equal fares — most of your repeat customers live at your hub.
• Don't hand them an invitation. Rivals look hardest at routes you fly nearly full at fares well above the market reference. An entrant that gets in tends to stay. It only retreats to a token schedule after months of fares below the reference, and it comes back if you push fares up again. At the hub, fair fares and enough frequency to keep loads below the brim are cheaper than a fight.
• Don't overreact elsewhere. If a competitor attacks a spoke, decide whether it's strategic (feed for your long-haul) or expendable. Defending everything means defending nothing.

The second hub: when and where

The most common expansion mistake is opening a second hub too early. A second hub splits your fleet, your cash, and your attention. Open one only when all three are true:

• Your first hub is saturated — the good spokes are flown, frequencies are healthy, and additional aircraft there face diminishing returns.
• You have a cash cushion that can absorb months of the new hub losing money while its network matures. Every hub starts as a money pit; the question is how long yours can afford to be.
• The new hub complements the old one. The ideal second hub sits far enough away to open a new catchment, close enough to connect with a profitable trunk route between the two. That trunk becomes the spine of your airline — fed at both ends, it's often the most profitable route you'll ever fly.

Geographically, think in pairs a continent apart, or one hub each on two sides of a dense region. Full hubs must be in your home country, so a continent-wide pair is easiest from a big country. Abroad, you are limited to one Focus City per country. Two hubs 700 km apart mostly cannibalise each other's catchments.

Common hub mistakes

1. Starting at a mega-hub because it's famous. Prestige doesn't pay leases. Competition intensity matters more than airport size early on.
2. Point-to-point sprawl. Routes scattered across the map with no common endpoint earn only local demand and are individually fragile. Concentrate.
3. Long-haul before feed. A widebody launched from a hub with three spokes flies mostly empty. Build the funnel before the firehose.
4. Ignoring the trunk between hubs. If you run two hubs and don't connect them generously, you're running two small airlines instead of one big one.
