Amadeus DNE Command: Aircraft Code Encode/Decode

A complete guide to the DNE command in Amadeus — how to encode and decode aircraft types and identify the correct aircraft code for a booking.

Aircraft types in the GDS are identified by three-character codes, not by their full names. When you see a code such as AB3 in a schedule, an availability display, or a fare rule, you need to know which aircraft it refers to. Conversely, when a customer asks whether a specific aircraft type is used on a flight, you need the code to check. The DNE command is the Amadeus entry that handles this. It allows you to find the three-letter aircraft code from an aircraft name, or identify the aircraft type from its code. This guide explains what DNE does, the syntax for each variation, and when it should be used.

What Does the DNE Command Do?

DNE is the Amadeus GDS command used to encode and decode aircraft types.

Category: Encoding & Decoding.

It allows you to find the three-letter aircraft code from an aircraft name or identify the aircraft type from its code. The aircraft code consists of three characters, and DNE is the correct entry whenever you need to identify one of them.

Encode an Aircraft Name into its Three-Letter Code

Display the three-letter code for the aircraft type:

DNEBOEING

This displays the three-letter code for the aircraft type matching Boeing. Use it when you know the manufacturer or aircraft name but not the code — the system returns the code you need.

Decode a Three-Letter Aircraft Code into its Name

Display the aircraft type corresponding to the code AB3:

DNEAB3

This displays the aircraft type corresponding to the code AB3. Use it when you see a three-letter code in a schedule, availability display, or fare rule and need to confirm which aircraft it refers to before advising the customer.

Important Notes

Use DNE when you need to identify an aircraft type or aircraft code.
The aircraft code consists of three characters.
DNE is part of the Amadeus encoding and decoding toolkit — the same command family used for airlines, hotels, car rentals, cities, and other reference data.

When to Use DNE

Use DNE during the encoding and decoding step whenever you need to identify an aircraft type from its code or find its code from the aircraft name. Typical scenarios include:

Checking which aircraft operates a specific flight when the display shows only the code.
Confirming the aircraft type before selling a segment or advising the customer.
Finding the three-letter code when you know the aircraft name or manufacturer.
Interpreting a code that appears in a fare rule, a ticket, or a supplier document.
Confirming the aircraft type on a booking taken over from another agent.
Explaining the aircraft configuration to a customer who has specific preferences.
Verifying the aircraft code when preparing a schedule change or rebooking.

How DNE Fits Into Your PNR Management Workflow

A typical session using DNE might look like this:

Retrieve the PNR with RT or open availability with AN.
When an aircraft code appears and you need to know the type, enter the DNE entry — for example DNEAB3 or DNEBOEING.
Note the result and share it with the customer if needed.
Check the full flight details with DO if you need to confirm the schedule and equipment together.
Add a remark with RM if the aircraft information should be documented in the PNR.
Sell the segment with SS once the aircraft type is confirmed.
Continue with pricing using FXP.

How DNE Relates to Other Encoding and Decoding Commands

DNE → encodes and decodes aircraft types and codes.
DAN → encodes and decodes airline names and codes.
DNA → related airline name decoding command.
DNH → encodes and decodes hotel company codes and displays master chain hotels.
DNC → encodes and decodes car rental company codes.
DNS → related state or reference data decoding command.
DAC → related airline or reference decoding command.
DO → displays detailed flight information, including aircraft type.

The distinction matters: DNE handles aircraft types specifically, while DAN and DNA handle airlines, DNH handles hotels, DNC handles car rentals, and DNS and DAC handle other reference data. Use DNE whenever the question is about the aircraft itself.

Important: DNE returns the aircraft type or code only. It does not confirm which aircraft is scheduled on a specific flight, nor does it guarantee the aircraft that will actually operate the route — airlines substitute equipment frequently, sometimes within hours of departure.

For the aircraft currently listed on a specific flight, use DO to display the flight details, then confirm the equipment with DNE if the code needs to be decoded.

Frequently Asked Questions

What does the DNE command do in Amadeus?

DNE encodes and decodes aircraft types — it finds the three-letter code from an aircraft name, or the aircraft type from a code.

What does DNEBOEING mean?

It displays the three-letter code for the aircraft type matching Boeing.

What does DNEAB3 mean?

It displays the aircraft type corresponding to the code AB3.

How long is an aircraft code?

The aircraft code consists of three characters.

How is DNE different from DNH or DNC?

DNH handles hotel codes, DNC handles car rental company codes, and DNE handles aircraft types.

Does DNE tell me which aircraft will operate my flight?

No. DNE only decodes the aircraft code. To see the aircraft currently scheduled on a flight, use DO and confirm the equipment before advising the customer.

Conclusion

The DNE command is the aircraft encoding and decoding tool in Amadeus. Use DNEBOEING to find the three-letter code for an aircraft name, and DNEAB3 to decode a code into its aircraft type. It removes the need for external reference lists and is essential when a customer asks about the aircraft on a specific flight, when a code appears in a schedule or fare rule without explanation, or when you need to confirm the equipment before selling a segment. Remember that DNE only handles aircraft codes — for the specific aircraft scheduled on a flight, use DO and check the equipment details, since airlines substitute aircraft frequently. Paired with the other encoding and decoding commands — DAN and DNA for airlines, DNH for hotels, DNC for car rentals, and DNS and DAC for other reference data — DNE completes your reference data toolkit and keeps every booking accurate from first entry to final ticket.
