Spending & prices

Your first claim is free. Every claim after that costs Ⓐ25,000multiplied by how many you've already paid for: the second claim is Ⓐ25,000, the third Ⓐ50,000, and so on. Land is deliberately the scarce thing in the economy - it's the one purchase that is never refunded (see Claiming land).

Every airport starts on the free starter level. Bigger circles are bought as levels, and prices are cumulative- an upgrade only ever charges the difference between what you've paid and the level you're buying.

Sizes, what each level unlocks, and how the circle behaves are covered in Buildable area & levels.

There is no flat per-category price. Every object in the catalogue is priced by a formula with three ingredients:

• Size score. Footprint and height combine into a size score - footprint dominates - which runs through a gently super-linear curve. Twice the building costs a bit more than twice the price.
• Category desirability. A multiplier for how much an object type is worth wanting: landmarks sit highest at 2.0, control towers at 1.6, terminals at 1.5, sliding down to 0.5 for simple clutter.
• Model richness.A factor derived from the 3D asset's actual detail, so an intricate model costs more than a plain box of the same size.

The result is rounded to a neat number, with a floor around Ⓐ60 for tiny items. Every category also has a ceiling that tracks its character: scatter decor caps low (a tree never exceeds Ⓐ400), hangars at Ⓐ10,000, terminals at Ⓐ15,000, bridges at Ⓐ20,000. Landmarks reach highest: formula-priced ones cap at Ⓐ60,000, and hand-priced world icons top the catalogue at Ⓐ70,000 - see Landmarks & prestige.

Two deliberate exceptions to "small = cheap": dynamic elements that answer the live world - windsocks and flags waving in the real wind - are premium set-dressing at Ⓐ400-Ⓐ500, and helipads are priced like hangars because placing one also compiles a real, spawnable helipad into your airport.

Practical anchors

Objects are bought as instances into an account-wide pool, not welded to one airport. Delete a placement and the instance goes back to your pool, ready to place again - at the same airport or any other one you own. You only buy a new instance when every one you own is already placed somewhere.

What limits object count isn't money, it's slots - see Object slots.

A lot of the builder never touches your wallet, on purpose:

• Parking spots, hold-shorts, taxi signs, and ground text - operational realism is never paywalled.
• Ground cover - the natural grass/dirt/gravel underlay.
• Moving or shrinking your buildable area.
• Rebuilding - compile and sync as often as you like.
• Releasing objects back to your pool.

Three refund rules cover everything: unused object instances refund at 100%; unused purchased material area refunds at 25%; and releasing a whole claim refunds 40% of what you spent on materials there - the land price itself is never returned.
