# How do I find the aircraft type for my flight?

> **Entwurf.** Dieser Beitrag erfüllt die Redaktionsregel noch nicht vollständig und ist nicht indexiert.

The aircraft type determines seat pitch, seat width, which cabins exist, screens and power outlets, and it sits in the booking detail view as a short code beside the flight number. The answer becomes reliable only with the seat map of the specific flight, because one airline operates the same type in several configurations.


## At a glance

| Question | Source |
|---|---|
| Which model operates | booking details, code beside the flight number |
| Which configuration | seat map of the specific flight |
| Pitch and width | seat map service, by airline and variant |
| Outlets and screens | seat map or the airline's own page |
| What actually flew recently | flight tracking service, by flight number |
| Whether a swap happened | new boarding pass, changed seat number |

## Why the type says more than the price

Two tickets on the same route at the same price can be entirely different flights. The fare is
identical; the difference sits in the [aircraft type](/en/glossary/aircraft-type).

Five properties follow directly from the model and its configuration. **Pitch** and **width**
decide comfort, and the underlying measurements sit in [seat pitch](/en/seat-pitch). The
**cabins** decide whether a [premium economy](/en/glossary/premium-economy) exists at all. The **fittings at the seat**, meaning
screen, outlet and connectivity, follow the configuration. And the **cabin environment**, meaning
noise, pressure and humidity, differs markedly between generations.

On a one-hour flight all of that is secondary and hardly worth researching. On a twelve-hour
flight it is the difference between arriving rested and arriving wrecked, and it usually costs
nothing, requiring only that you pick the right one of two connections.

Safety is not part of this comparison. Certified models in scheduled service meet the same
requirements, and in any practical sense the type tells a passenger nothing about risk. What it does
tell, through its configuration, is how the next nine or twelve hours will feel. Whether a seat has
a power outlet, for example, depends on how the airline fitted the cabin, so the same model can
offer one on one carrier and not on another.

## What differs between generations

Differences between two models reduce to four variables, and only the first is widely known.

**Seating density** is the most visible. The airline decides it, not the manufacturer, but newer
fuselages allow one more seat across, and many carriers use that. How
pitch and width relate is covered in [seat pitch](/en/seat-pitch).

**Cabin pressure** differs noticeably between generations. Composite fuselages tolerate a lower
cabin altitude, which means less strain on passengers.

**Humidity** is higher for the same reason, because composites do not corrode. On long-haul
flights that is the most noticeable difference after the seat itself.

**Noise** depends on the engines and the insulation and differs between two models by several
decibels. Inside one aircraft it varies further by row, and the quietest seats sit forward of the
wing.

## Where the information sits

### In the booking view

Nearly every [booking site](/en/glossary/online-travel-agency) shows the type, but rarely at the first level. It sits in the flight
details, usually as three characters beside the flight number and the duration. The codes follow
an international standard and name the model, not the configuration.

One detail misleads regularly: some sites show a code covering a whole family without naming the
sub-variant. For the cabin the sub-variant is the deciding information, because length and layout
differ.

### In the seat map for the flight

The answer becomes reliable with the seat map shown at seat selection. That map belongs to the
aircraft scheduled for this flight, not to the fleet as a whole. From it you can read the number of seats per
row, the position of [exit rows](/en/glossary/exit-row) and the areas with different pitch.

Before booking, the map can still be reached by running the booking flow as far as seat selection
and stopping there. No other route shows the real configuration before paying.

### At a seat map service

Independent services keep seat maps by airline and configuration and add pitch, width, outlets and
problem seats. They are the most informative source and the most fragile, because they depend on
reports and can be months out of date after a cabin refit.

### In a flight tracking service

Flight tracking services answer a different question: which model flew this flight number over
recent weeks. The history is no promise for your own date, but it shows how stable the allocation
is. A flight number that carried one model for thirty days will very likely carry it tomorrow. One
that alternates between two is a gamble, and a traveller who depends on a particular cabin is better
off with a different connection.

## Why the same route is configured differently

Airlines allocate fleet by demand, and the route is only one input. Three patterns recur almost
everywhere.

The first is **time of day**. Mornings and evenings on business routes see larger aircraft than
midday, because demand is higher. The second is **season**. On leisure routes the configuration changes between summer and winter,
and in winter some of those flights lose the upper cabin entirely.

The third is **mixed fleets**. After a merger or during a refit an airline runs the same type
in two or three variants side by side. One has a premium economy and another does not, and both
carry the same code.

The useful question at booking is therefore which aircraft flies this connection on this day. Which
aircraft serves the route says little.

## Worked example: two connections at the same price

Two flights to North America cost 690 euros. The first uses an older widebody configured with ten
seats across, the second a newer model configured with nine.

The difference is roughly three centimetres of seat width per person across nine
hours. The newer model adds a lower cabin altitude and higher humidity, which widens the gap by
arrival. The price is identical, the booking takes the same time, and the information costs two
minutes of looking.

With 200 euros between the two connections this would be a trade-off. At the same price it is not.
The check costs nothing and delivers the largest single comfort gain available without paying
extra, which makes it the best use of two minutes in the whole booking process.

## Choosing a seat from the map

Once the model is settled, the seat map is the real tool. Six places deserve a look, and all six
can be read off the drawing.

**Exit rows** show as a larger gap between two rows. Their conditions sit in
[exit row seats](/en/exit-row-seats).

**Rows in front of an exit** frequently have a fixed seat back so the path stays clear. On the map
they sit immediately before the gap.

**Galleys and lavatories** appear as blocks without seats. Seats beside them are louder and busier,
particularly overnight.

**Bulkhead rows** have plenty of [legroom](/en/glossary/seat-pitch), no space under the seat in front, and sometimes a screen
in the armrest that narrows the seat.

**The last row** sits against a wall and frequently does not recline.

And **rows over the wing** are the quietest towards the front, the noisiest towards the rear, and
move least in turbulence.

## How to spot a swap

An aircraft assignment is a plan, not a promise. Swaps happen for operational reasons,
after disruption or for maintenance.

Three signs give it away. A **changed seat number** in the booking overview, frequently with no
notification. A **different seat map** in the app from the one at purchase. And a **newly issued
boarding pass** shortly before departure.

A passenger who paid for a seat and does not get it after a swap is entitled to a [refund](/en/glossary/refund) of the fee. It
is rarely returned automatically, and how to establish the claim sits in
[seat selection fees](/en/seat-selection-fees).

A swap can also work in the other direction, and that case is rarely used. Where a larger model is
substituted, extra seats appear and occasionally a cabin that did not exist before. Opening the
seat map again the day before sometimes turns up a better seat that has been released, and
changing costs nothing at that moment.

## Why airlines keep the information quiet

The type appears in nearly every booking view but rarely prominently, and there is a reason.

An airline running two variants of the same model has no interest in making the difference a
purchase criterion. If both were visible side by side at the same price, the worse one would stay
empty and the better one would sell out immediately. Travellers would gain nothing; the airline
would simply open a price gap between the two.

A second reason is operational. Promising the assignment prominently would mean having to honour
it, and a swap would become a change of service rather than internal scheduling. Airlines
therefore describe the information as non-binding throughout.

Complaining about that changes little. The information exists and is accessible, it is simply not
advertised. Looking finds it in two minutes; not looking means it is never offered. Few details in
the booking process separate experienced travellers from occasional ones as sharply.

## When it is not worth checking

Below two hours the difference between models is small. Departure time, connection and price weigh
far more heavily than the cabin, and the effort is rarely repaid.

Where a booking has no alternative, one connection a day for instance, the knowledge changes
nothing about the decision. It helps at most with seat selection.

Where the booking is a basic fare with no seat selection at all, the knowledge has nowhere to go.
What such fares otherwise restrict is covered in [basic fares](/en/basic-economy).

Where a flight is booked far ahead, the assignment is still unstable. Months out, close checking
earns little, because it can change several times before departure. Rough at booking and precise
in the week before the flight is the right cadence: two minutes to pick the connection, two minutes
the day before to check that it still holds.

Regular routes need even less. Frequent travellers who keep a short personal list of which models
are pleasant on their routes, and which are not, can stop researching after a handful of trips,
because fleets change more slowly than schedules.

## The most common mistakes

- **Asking about the route instead of the connection.** Day and time decide the aircraft as much as
  the route does.
- **Reading the code as the configuration.** One model comes in several variants, and the code does
  not say which.
- **Relying on a seat map service alone.** Such services can lag months behind a refit; the
  booking's own map is the one to cross-check against.
- **Treating an assignment months out as settled.** It can change several times, so it needs another
  look in the week before departure.
- **Missing a swap.** Opening the seat map the day before catches most of them.
- **Letting the [seat fee](/en/glossary/seat-selection-fee) lapse after a swap.** Refunds rarely
  arrive on their own. Ask for it explicitly.
- **Looking at the seat map only after booking.** Running the flow to seat selection and stopping
  there shows the cabin before any money changes hands.

## Frequently asked questions

### Where does the aircraft type appear when booking?

Usually as a three-character code beside the flight number in the detail view, frequently visible only after opening the flight details.

### What do the codes mean?

They follow an international code for aircraft models. The code names the model, not the configuration an airline fits inside it.

### Why does one route use different types?

Because airlines allocate fleet by demand. Mornings and evenings on business routes often see larger aircraft than midday.

### How do I find the configuration?

Through the seat map of the specific flight during booking, or through a seat map service that separates airline and variant.

### How reliable is it before departure?

Until roughly twenty-four hours out it is a plan. A swap stays possible until departure and happens regularly after disruption.

### How do I spot a swap?

A changed seat number, a newly issued boarding pass, or a seat map in the app that suddenly looks different.

### Do I get my seat fee back after a swap?

Where the paid seat is not provided, yes. The claim has to be made, because refunds rarely happen automatically.

### Does the type say anything about safety?

Not in any practical sense. Certified models in scheduled service meet the same requirements, and the differences concern comfort.

### Why does it matter for frequent flyers?

Because it decides pitch, width, noise, humidity and fittings. On long-haul routes those add up to a noticeable difference on arrival.

### Where do I find whether there are power outlets?

In the airline's seat map or at a seat map service. The answer depends on the configuration rather than on the model.

### Does the flight number help?

Yes. Flight tracking services show which models operated that number over recent weeks, which indicates how stable the allocation is.

### Is it worth checking on short flights?

Rarely. Below two hours the departure time matters more than the cabin, and differences between models are small.
