Waitlisted seat in GDS means an unconfirmed seat booked by the travel agent. If a specific class is not available and you want to keep it on the waitlist, then for that we use the waitlist command. Understanding how to manage a flight segment waitlisted status is crucial for travel agents and passengers alike, especially when navigating systems like Galileo, Amadeus, and Sabre.
In this guide, we will explore how to waitlist a flight segment, understand the status codes, and manage bookings across different platforms.
Understanding Flight Availability and Classes
First of all, I am going to search a flight on September 1st from Bahrain to Dubai. Here you can see there are many lane numbers; there are many flights operating from Bahrain to Dubai. So I’m going to select line number 15 and you need N class (Nancy class). But as you can see here, Nancy class availability is 0, that means it is not available at present.
So whenever there is a zero seat in some class or whenever it’s mentioned L with some class like this, then we can waitlist the seat in that particular class. And the classes which have the code C beside them, it means that the class is closed for booking.
Closed vs. Waitlistable Classes
If you carefully look at line number three, we have zero seats in R class. Line number four and five, which is a connecting flight for Delhi to Istanbul via Dubai, is actually closed for booking because all the classes are showing C code with the classes. So if you want to waitlist a seat, we can waitlist a seat only in those classes where it is written 0 with the class or where it is written L with the class.
If we try to book this class, then our seat should not be picked up. If I try to book a seat in R class for the same itinerary, then my seat should be booked on waitlist.
How to Waitlist a Flight Segment in GDS
So for the time being, I want to waitlist this flight line number 15 and booking or class is Nancy. So I will show you how to waitlist this one.
Using Sabre
In Sabre training sessions, we will see how to waitlist a seat. The command is: 0 (zero) then the number of seats then the class and then the line number. But for waitlist, we add “LL” after the class.
Example Command: 01Y1LL
Here “01” is for one seat, “Y” is the class, and “1” is the line number. “LL” means waitlist. After entering, you will see that the status is showing as “LL”. This means that your request has gone into the waitlist.
Step-by-Step for Connecting Flights:
Now I will show you how to waitlist a connecting flight like on 29th of August from Dammam to Cochin via Bahrain. So I want to waitlist a flight line number 13 and 14 because number 13 is from Dammam to Bahrain and number 14 is from Bahrain to Cochin.
The entry would be: 01H13*14LL (Note: specific syntax varies slightly based on the exact GDS version but generally involves segment selection and LL code). Now you can see the difference here: see line number segment number one it is wait-listed at the same time Bahrain to Cochin is confirmed means SS means confirmed. This is wait-listed.
Using Galileo
Let’s waitlist the seat in G Class. To waitlist the seat in G Class, we will use the normal sell command which is N1. It means one passenger G Class line number three. So we are going to waitlist a seat in G Class in line number three. So this is the normal command wherein we sell a seat to waitlist; we use code LL, which stands for waitlist, and we enter.
Now if you see on the left-hand side you have got the itinerary sold. It’s showing LL1 here which means you have picked up or you have sold a waitlist seat and your seat has been picked up by the system.
Status Codes: Decoding Airline Responses
Status codes are really important to understand because that is how the airline will revert you and that is the only way we can understand what reward the airline has given us. Has the airline rejected our request or has the airline accepted or kept it on hold?
Here you can see it’s mentioned HL1, which means that holding is waitlisted. Before I am filing this PNR you can see it was LL. After I save the PNR that has become HL means holding wait-listed.
Common Status Codes Table
| Code | Meaning | Action Required |
|---|---|---|
| LL | Waitlist Request | Initial request by agent |
| HL | Holding Waitlist | Airline has received request |
| KL | Confirming from Waitlist | Change manually to HK |
| KK | Carrier Confirmed | Change manually to HK |
| HK | Holding Confirmed | Ticket can be issued |
| NO | No Action Taken / Rejected | Rebook or find alternative |
| TK | Time Change | Advise passenger of new time |
So if the airline would confirm this holding, then the airline would either revert with the KL code or with the HK code. So this HL will eventually get changed to KL which means airline is confirming from the waitlist. And if the travel agent gets KL code then the travel agent needs to manually convert it into HK.
Please note here if the airline is reverting you with the KL code, it means your line is confirming your seat from the waitlist inventory and in this case, if your line accepts this particular itinerary then the travel agent must change the element manually to HK.
If you encounter issues where confirmation seems stuck, it might feel like the time you checked in but got no boarding pass. Patience and monitoring the queue are key.
Managing the PNR and Ticketing
Once you get the confirmation from the airline, you will get a message to your queue. You can check your queues periodically and you will find the confirmation once the airlines send the message. Okay then you can issue it accordingly.
After this, we will fill the rest of the mandatory fields. Like name: -SURNAME/NAME, Phone number: 9 phone number, Ticketing field: 7T-, Received from: 6NAME, and for end of transaction: ER.
You can see the PNR has been created and the status is still “LL”. When the seat is confirmed the airline will convert this into “KK” status. Then you will have to confirm it into “HK” status. That time you can issue the ticket like normally normal procedure.
Handling Connecting Flights with Mixed Status
Now you can see the difference here. Line number segment number one it is wait-listed at the same time Bahrain to Cochin is confirmed. Now you can close the PNR by entering name and all those other implemented information. And as same as that before once the flight got confirmed you will get a message from the airline.
Sometimes travelers look for deals on apps that specialize in finding these openings. You might wonder what happened to Hitlist app and if it could help with waitlisted flights.
Important Considerations for Waitlisted Segments
There is a duplicate segment for the same passenger in the same airline or other airline or maybe other PNR. Then that duplicate segment or the duplicate PNR should be removed at least 24 hours before the departure time. But it is always advised to remove at least 70 hours before the departure time to avoid ADMs (Agency Debit Memos).
If you are planning a complex trip with groups, like comparing Contiki vs EF Ultimate Break, having a waitlisted segment can throw a wrench in the plans, so timely management is essential.
Flight Segment Waitlist: Frequently Asked Questions
1. What does it mean when a flight segment is “waitlisted”?
It means your seat on that specific part of your journey is not yet confirmed because the cabin or fare class is currently full. You are placed on a priority list and will only receive a confirmed seat if another passenger cancels or the airline releases more inventory.
2. Is a waitlisted segment the same as a confirmed booking?
No, a waitlisted segment is a “request” for space rather than a guaranteed seat on the aircraft. You do not have a valid ticket for that segment until the status changes from “HL” (Waitlisted) to “HK” (Holds Confirmed).
3. Why was my flight segment waitlisted in the first place?
This usually happens when you try to book a specific discounted fare or an award seat that is no longer available. Airlines also use waitlists for passengers seeking upgrades to Business or First Class when those cabins are at capacity.
4. How can I check the status of my waitlisted segment?
You can monitor your status through the airline’s “Manage Booking” portal or by checking your PNR status on a flight tracking app. If your status code changes from “LL” or “HL” to “KL” or “HK,” it means your seat has been confirmed.
5. What are the chances of a waitlisted flight segment clearing?
Your chances depend on your frequent flyer status, the type of fare purchased, and how close you are to the departure date. High-tier elite members are always prioritized, and seats are more likely to open up right before the 24-hour check-in window.
6. Do I have to pay for a flight if I am still waitlisted?
Generally, you do not pay the full fare or miles for a waitlisted segment until it is officially confirmed. However, some airlines may require a “hold” on your credit card or miles which is only processed once the seat becomes available.
7. Can I be waitlisted and confirmed on two different flights for the same day?
Yes, passengers often hold a confirmed seat on one flight while waitlisting for a more desirable time or class on another. If the waitlisted segment clears, the system will usually automatically cancel your original confirmed segment to avoid duplication.
8. What is the difference between being “Waitlisted” and “Standby”?
Waitlisting happens days or weeks before a flight and is managed by the airline’s reservation system. Standby typically occurs at the airport on the day of departure, where you wait at the gate to see if any seats remain after all confirmed passengers have boarded.
9. What happens if my waitlist never clears?
If the waitlist doesn’t clear by a certain cutoff (usually 24–72 hours before departure), the segment will be automatically cancelled. In this case, you will either remain on your original confirmed flight or need to book an alternative route.
10. Can I increase my priority on the waitlist?
The most effective way to move up the list is by having elite status with the airline or its partners. You can also improve your odds by booking a higher fare class, as airlines prioritize “full-fare” passengers over those on discounted tickets.
Conclusion
This is how you waitlist a flight in Sabre and Galileo. If a specific class is not available and you want to keep it on the waitlist, then for that we use the “LL” command. Once the flight got confirmed you will get a message from the airline it will the message will be sent to your queue.
