The flight
The run launches from an airport runway at one end of the level, with a terminal building and parked planes beside the strip. The course crosses a rocky gap onto the main island, passing a downtown block of glass high-rises and mid-rise buildings, then a long stretch of suburban neighborhoods laid out on a road grid with houses, trees, and fenced yards. Past the suburbs the terrain narrows into a green strip flanked by cliffs and water, tapering off into a thin line of trees that marks the far end of the roughly 4,200-unit course.
Upgrades in this world
Each stage is 5 levels. Engine and Slingshot share the same price curve, so their early levels cost the same. The full level-by-level table, with the plane’s evolution at each unlock, is on the Commercial plane page.

The multiplier doubles every stage.
| Stage | Levels | Multiplier reached | Cost per level |
|---|---|---|---|
| 1 | 1–5 | ×44.8 | 100 → 506 |

Engine is the money pit: 88% of the 4.24B it takes to max this world. Income pays for itself fastest, so keep it ahead of the other two.
