How to Master Amadeus Encode & Decode Commands

In the Amadeus GDS system, travel agents rely on quick encode and decode commands to retrieve essential travel data such as city and airport codes, airline information, country codes, and aircraft types. These commands are widely used to speed up reservations and improve accuracy during booking.

This guide explains the most important Amadeus ENCODE and DECODE commands in a simple, practical, and human way.

1. DAN – Cities & Airports

Encode (name → code): dan cairo → returns CAI
Partial match: dan ca* → lists all cities/airports starting with “ca”
Decode (code → name): dan jfk → returns “John F. Kennedy International Airport”

2. DAC – Decode Airport Code

dac cai → “Cairo International Airport” (city name)

3. DNA – Airlines

Encode airline by name: dna aircairo → returns airline code (e.g., SM)
Decode 2‑letter code: dna SM → airline name
Decode 3‑digit numeric: dna 381 → airline name

4. DC – Countries

Encode country name: dc egypt → EG
Decode country code: dc eg → “Egypt”

5. DNE – Aircraft

Decode equipment code: DNE 788 → “Boeing 787-8”

Encode aircraft name: DNEairbus a320 → equipment code (e.g., 320)
