Every aircraft in your fleet carries its own cabin layout: a seat count per class, plus optional cargo space. The layout decides how many tickets each flight can sell, so it is one of the most consequential choices you make per tail.
The four classes#
| Class | Floor space per seat (default) | Fallback fare vs Economy (default) |
|---|---|---|
| Economy | 1.0 | 1.0× |
| Premium Economy | 1.5 | 1.6× |
| Business | 2.5 | 2.8× |
| First | 4.0 | 4.5× |
Floor-space weights and fare multipliers are world settings: by default a First seat takes four times the space of an Economy seat (your world may differ). If you don't publish an explicit fare for a premium class, it sells at the fallback multiple of your Economy fare; see Pricing & fares.
Fitting a layout#
Each aircraft type has a fixed floor-space budget. Your seats and cargo units must fit inside it, so every premium seat you add costs you more than one Economy seat elsewhere. Factory-fresh aircraft arrive in a dense all-Economy layout (one Economy seat per unit of floor space), so reconfiguring is usually your first move on a premium-minded network. A tail you lease or buy second-hand is different: it keeps whatever layout it already wears, and larger lessor metal often arrives with a business cabin already fitted, so check before you plan a refit.
On the Cabins page you can edit a tail's layout directly, or save named layouts per aircraft type and install them with one click. Saved layouts are copies: editing or deleting one never touches aircraft that already wear it.
When a refit takes effect#
On most worlds reconfiguring a cabin is instant and free, and the aircraft stays in service. The new layout applies to every flight still ahead of the aircraft, including the ones already on sale. Passengers who no longer fit are re-seated where another cabin has room and bumped with compensation where none does, so shrinking a cabin mid-week costs you the seats you had already sold. Flights that have flown keep their record.
Worlds that enable refit windows make it a real project instead: the seats are billed as hardware, the tail is grounded for the work, and overlapping flights are cancelled with compensation. The Cabins page warns you before you commit, so you will know which kind of world you are in.
Long sectors shrink the cabin#
Capacity is not always the full layout. Past an aircraft type's full-payload range, the game trims the sellable seats on that leg, proportionally across all classes, falling toward zero at the type's absolute maximum range. A layout that works on short hops may sell noticeably fewer seats on the type's longest missions, and leftover payload is what carries belly cargo.
Why premium cabins earn their space#
Passengers are not interchangeable. Different traveler types value comfort differently, and comfort is valued per hour: a Business seat is worth far more on a ten-hour sector than a one-hour hop. Some travelers only consider certain classes at all, and premium passengers also expect a higher service standard. The Cabins page includes a comfort-by-distance view to help you judge where premium space pays. How passengers actually choose between your options is covered in How booking works.
Cabin choice also interacts with what metal you fly; see Leasing, buying & ordering.
