# Where seat selection revenue comes from

Seats are the anchor ancillary because everybody needs one. How airlines price seats by position, and why cabin accuracy decides whether the sale completes.

Every traveller sits somewhere. It sounds too obvious to be a commercial
observation, and it is the entire reason seat selection behaves differently from
every other item in a post-booking cart.

Seat selection is the anchor ancillary because it is relevant to every traveller
on every flight, priced low enough to be an easy decision, and multiplied by the
number of people on the booking. Its revenue depends less on the price asked
than on whether the cabin shown to the traveller is the real one.

## Relevance is the whole advantage

Most extras are relevant to a slice of travellers. A long connection makes one
product sensible and a short one makes it pointless. A destination makes another
product obvious and irrelevant everywhere else. That is normal, and it is why a
broad catalogue matters.

Seats have no such filter. There is no itinerary where the question does not
apply, no traveller it does not apply to, and no need to explain what is being
sold. The ceiling on a seat programme is the entire base of bookings, which is
not true of anything else you might put in the cart.

## A small decision, taken many times

The amount asked for a seat is usually modest, and that is a feature. A small
amount is decided in seconds, with no research and no second opinion. It sits
below the threshold where a traveller goes looking for a comparison.

It also multiplies in a way most extras do not. One traveller usually buys one
bag for a whole party, but four people on a booking make four seat decisions.
A programme measuring seat performance against bookings rather than passengers
is quietly understating itself, which is one of the clearest cases for choosing
the denominator deliberately.

## Airlines price the position, not the seat

Seat pricing is a ladder, and the rungs are physical properties of where the
seat sits rather than anything about the seat itself.

**Illustrative seat prices by position**

| Category | Illustrative multiple of the cheapest seat |
| --- | --- |
| Standard, rear cabin | 1.0x |
| Standard, forward cabin | 1.5x |
| Window or aisle, forward | 2.0x |
| Extra legroom row | 3.0x |
| Exit row | 4.0x |

Airlines price seats by position rather than by seat. The figures here are round illustrative multiples of the cheapest seat, chosen to show the shape of the ladder. They are not filed prices and not measured data.

Four things drive the ladder: how much room there is in front of the seat, how
close it is to a door at either end, whether the traveller is buying a specific
neighbour arrangement, and how many of that kind of seat exist. The last one is
the interesting one commercially, because scarcity here is physical. An aircraft
has a fixed and small number of exit row and bulkhead positions, so those rungs
sell out rather than scale.

The ladder is also why an average seat price tells you almost nothing. Two
airlines with identical averages can have completely different revenue, because
one sold a wide spread across the ladder and the other sold the bottom rung to
everybody.

## Accuracy is what decides whether the sale completes

A traveller who has decided to buy a seat has already done the hard part. What
remains is a picture of a cabin, and that picture has one job: be the aircraft
they are actually flying on.

[Diagram: A researched cabin layout records the cabins on the aircraft, how many seats sit abreast, the pitch between rows, which rows are exit rows, which rows sit over the wing, and where bassinet positions are fitted. That is what lets a seat map show a traveller the real cabin rather than a generic grid.]

What a researched layout has to record before a map can be trusted.

A generic grid fails in ways that are obvious to the person looking at it. The
row numbers stop before theirs. There are six seats across where the aircraft
has four. The exit row is drawn in the wrong place, so the extra legroom being
sold is not where the legroom is. Each of these lands at the last step of the
purchase, after every earlier step worked, which makes it the most expensive
place in the whole funnel to lose someone.

Worse than losing the sale is completing a wrong one. A seat sold on an aircraft
that does not have it becomes a refund, a support contact, and a traveller
arriving at the gate unsure where they are sitting. The cost of that is not the
seat price.

Accuracy has to be per aircraft type rather than per airline, because a single
route can be flown by more than one type and the layout changes with it. That is
the part that takes real work, and it is the part travellers never notice when
it is right.

## Selling a seat and selling a better seat

These read as one product and behave as two.

An assignment is bought for certainty. The motive is usually a party sitting
together, or a strong preference for an aisle, and the traveller is price
sensitive because what they are buying is the removal of a small anxiety.

A better position is bought for comfort. The traveller is paying for a physical
difference, and will pay several times the base amount for it, but only if the
difference is legible on the screen. Pitch, proximity to the wing and the doors,
and which rows recline are what make one rung visibly worth more than the one
below it.

**Insight:** Sell a grid and every seat looks the same, which leaves price as the only thing
distinguishing them. Sell an accurate cabin and the ladder explains itself,
because the traveller can see what the extra amount buys.

That is the whole argument for spending effort on layout data rather than on the
merchandising copy around it. The copy persuades someone to look. The cabin is
what they decide against.

## Frequently asked questions

### Why is seat selection called the anchor ancillary?

Because it is the only extra relevant to every traveller on every flight. Other products suit a subset of trips. A seat applies to all of them, which gives it the highest ceiling of any single item in the cart.

### Does an inaccurate cabin map really cost sales?

Yes, and it costs them at the last possible moment. A traveller who cannot find their own row, or who is shown seats the aircraft does not have, stops trusting the page. The sale was already won when the map lost it.

### What makes one seat worth more than another?

Position rather than the seat itself. Legroom, proximity to a door, whether the row reclines, and how easily a party can sit together. Scarcity is physical, because an aircraft has only a handful of the best positions.

### Is selling a better seat a different sale?

It is a different motive. An assignment is bought for certainty, usually so a party sits together. A better position is bought for comfort, and it only sells if the map communicates the physical difference clearly enough to be worth paying for.
