Fleet Planning: The Right Aircraft at the Right Time

Fleet decisions are the biggest financial commitments you make in Tailwinds. This guide covers the lease-versus-buy question, old versus new generations, fleet commonality, and how your fleet should evolve from startup to global carrier.

The golden rule: routes first, fleet second

Never lease an aircraft and then go looking for something to do with it. Every aircraft should be the answer to a question your route map is already asking: "what's the cheapest machine that can fly this mission with seats I can actually fill?" Fleet planning done in the other direction — falling in love with a jet and hunting for routes to justify it — is how hangar queens are born. An idle or half-utilised aircraft still pays its full weekly lease and maintenance.

Lease or buy?

In Tailwinds, leasing costs roughly 8–12% of an aircraft's market value per year, charged weekly, while buying pays the full price up front. The arithmetic gives clear guidance:

• Lease when you're growing. Early on, cash is your scarcest resource and flexibility your best defence. Leasing keeps money free for routes and lets you hand back a mistake. With ~$10M starting cash, buying anything meaningful is off the table anyway.
• Buy when cash is piling up and the aircraft is a keeper. Once an aircraft type has proven itself on routes you'll fly for years, buying eliminates the lease line forever. Over a long enough horizon, ownership wins — an aircraft leased for a decade costs about its own purchase price with nothing to show for it.
• Mixed fleets are sensible. Own the stable core (your hub workhorses on proven trunks), lease the experimental edge (new markets, seasonal capacity, anything you might regret).

Old classics vs. new generation

Almost every mission in the game has a budget option and a premium option: 737-800 or MAX 8, A330ceo or A350, CRJ or E2. The trade is always the same — the classic leases for much less, the new type burns meaningfully less fuel per seat. Which wins depends on utilisation and fuel:

• High utilisation favours new metal. The fuel saving is earned per kilometre flown, so an aircraft in the air all week pays back its lease premium fastest.
• Cheap leases favour patchy flying. If a route only supports a few weekly frequencies, the fuel savings never accumulate enough to matter — take the cheap classic.
• Fuel prices swing the maths. At a fuel index near the 0.55 floor, classics look brilliant. In a 1.9× crisis, efficient types are the only thing keeping long-haul alive. If you run classics, hedge more aggressively.
• Age raises maintenance. Maintenance bills grow with airframe age, quietly eating part of the classic's lease advantage — budget for it.

How many types is too many?

Each distinct category in your fleet adds real management overhead — more markets to understand, more spare capacity questions, more decisions every week. A practical progression:

1. Startup (1–2 types). One regional type (turboprop or regional jet) and at most one narrow-body. Master the weekly loop with a simple fleet. The turboprop and regional jet guides cover the candidates.
2. Regional carrier (2–3 types). Add a proper narrow-body workhorse as ring-two routes open. This trio can profitably serve 90% of routes under 5,000 km.
3. Going long-haul (3–4 types). One widebody family, chosen for your specific trunk missions. Resist collecting one of each — depth beats variety.
4. Mature carrier (4–6 types). Maybe a freighter line, maybe a flagship for your densest trunk. By now you have the cash and the data to justify exotic additions — or to know you don't need them.

Capacity discipline

The most expensive seats in the game are the ones flying empty. Signals to act on:

• Persistent load above ~85% — you're leaving demand on the table. Add frequency first (it also defends the route), then consider a size step up.
• Persistent load below ~60% — downsize the aircraft or cut frequency before touching fares. Cost per seat drops immediately; revenue usually barely moves.
• An aircraft with no good mission — return it. Paying a lease to avoid admitting a mistake is the sunk-cost fallacy with wings.

Planning the fleet's future

Your fleet ages, your network grows, and fuel prices wander — so revisit fleet strategy every in-game year or so. Questions worth asking on the review: Which types earn their keep per airframe? Is maintenance creep on older jets changing the classic-vs-new maths? Does the next stage of the network (second hub, long-haul push, cargo) need a type I don't fly yet — and can I enter it with one aircraft, prove it, then scale? The airlines that fail in Tailwinds usually don't die of one bad decision; they die of a fleet assembled by accident.
