Command to Add ARNK in Amadeus: The ARNK segment indicates that it is not known how the passenger proceeds from the arrival city of the previous segment to the departure city of the next segment. If you know the arrival date, you can add this in your entry, you can also add passenger association.
The system automatically places the ARNK segment between the non-sequential segments if you do not
enter a date.
What is Command to Add ARNK in Amadeus
Command to Add ARNK in Amadeus: In Amadeus, the command to add an ARNK (Arrival Unknown) segment helps in cases where there’s a gap between segments of a passenger’s itinerary, such as when a traveler makes a ground transfer (by car, train, or bus) or any form of travel that does not require booking an airline segment. It allows you to reflect this gap in the Passenger Name Record (PNR).
Here is a comprehensive guide explaining how to insert ARNK in Amadeus, including background information, step-by-step usage, and additional tips, with an aim to cover it in detail.
Step-by-Step Instructions for Command to Add ARNK in Amadeus
Step 1: Start with a PNR
Command to Add ARNK in Amadeus: Make sure you have already created the basic passenger name record (PNR). You can create a PNR with necessary passenger details and at least one flight segment.
Example of creating a basic PNR:
NM1SIMPSON/JOHNMR
AP LHR 0712345678
TKOK
Step 2: Add Flight Segments
Before adding an ARNK, there should be at least two flight segments, or at least a flight before or after the ARNK is inserted.
Example of adding flight segments:
SS BA 175 Y 15JUN JFKLHR
SS AF 123 Y 18JUN CDGTXL
Step 3: Insert ARNK
Command to Add ARNK in Amadeus: After adding flight segments, you’ll now insert the ARNK between the two destinations (London and Paris in this case).

This will automatically insert an ARNK segment between the first and second flight segments. You don’t need to specify airports for the ARNK since it’s implied by the gap between the preceding and following flight segments.
Step 4: Complete the PNR
Command to Add ARNK in Amadeus: Once the ARNK is inserted, complete the PNR by adding any remaining information, such as ticketing or seat requests.
Example PNR:
NM1SIMPSON/JOHNMR
SS BA 175 Y 15JUN JFKLHR
ARNK
SS AF 123 Y 18JUN CDGTXL
AP LHR 0712345678
TKOK
ER
After everything is entered, use ER to end and save the PNR, which will also return the PNR record locator.
Amadeus Tools for Itinerary Management
Command to Add ARNK in Amadeus: Amadeus offers a variety of tools to manage and adjust itineraries efficiently. If changes need to be made to an itinerary, including ARNK segments, the following commands can be helpful:
- Display itinerary (DOI): This command shows the full itinerary with all segments, including ARNK.
- Modify ARNK: If an ARNK segment needs to be repositioned, delete the original one with:
XE2
and reinsert it where needed using SKIP.
Key Considerations for ARNK Usage
- Compliance with airline rules: Some airlines might have restrictions or specific guidelines when handling itineraries with ARNK, particularly regarding ticketing and fare calculation. Make sure you’re familiar with the rules of the airline you’re working with.
- Ticketing: ARNK segments don’t require ticketing as they are placeholders and not flight segments. However, the ticketing for the surrounding segments needs to be processed as usual.
- Multi-city itineraries: ARNK is frequently used in multi-city itineraries where travelers use different modes of transportation between cities that are not linked by a direct flight.
Real-World Application of ARNK Segments
- Multi-leg Journeys: Travelers moving across various cities using different modes of transportation.
- Example: A traveler flying from New York to Tokyo but taking a train from Tokyo to Kyoto. The ARNK allows the system to record the Tokyo-Kyoto portion without needing to book a flight.
- Complex Itineraries: Business travelers frequently face complex itineraries with unlinked flights. ARNK helps manage these by maintaining the structure of the trip in the PNR.
- Intermodal Travel: With the rise of intermodal travel (combining air, rail, and other means of transport), ARNK is becoming increasingly important for accurate representation of itineraries in systems like Amadeus.
Troubleshooting ARNK in Amadeus
- Segment order issues: If an ARNK segment doesn’t align properly, recheck the surrounding segments and ensure the sequence of flights and ARNK entries are correct.
- Error messages: If Amadeus throws an error when adding an ARNK, the most common reasons include:
- A missing preceding or subsequent flight segment.
- Incorrect format for flight segments.
Conclusion
Command to Add ARNK in Amadeus: Using ARNK segments in Amadeus ensures that unbooked or non-flight portions of an itinerary are represented clearly and that all segments are properly ordered. The ARNK command is straightforward, and with practice, handling complex itineraries becomes efficient. This feature plays a critical role in organizing travel itineraries, ensuring both the system and travelers have an accurate overview of all segments, even if some involve ground or open-ended travel.
