What Ticketing time limit means
Airline seats can be reserved before they are paid for, but airlines do not want inventory held indefinitely. The ticketing time limit closes that gap: it tells the seller exactly how long a reservation will be held before it must become a paid e-ticket.
Two different deadlines often apply at once. The fare rules may set an advance purchase requirement, for example ticketing within a set number of days of booking. Separately, the airline's own revenue integrity systems may send a time limit based on booking class and how close departure is. Qatar Airways, for instance, tells agents that the stricter of the two applies.
Airlines commonly send their deadline as an SSR ADTK element in the PNR. Cathay Pacific describes the ADTK as the deadline for tickets to be issued, set from the PNR creation date and liable to change if the booking is changed. Amadeus users at some airlines see the same information as option elements instead.
When the deadline passes without a ticket, the airline cancels the segments, often marking them HX, and the record may be sent to the booking office's queue. Repeatedly cancelling and rebooking to extend a time limit is called churning and is treated as abuse by many airlines, often resulting in an ADM.
How Ticketing time limit works
The time limit is created at booking, can move with changes, and is enforced automatically by the airline.
- Booking is createdThe agent sells segments and saves the PNR. The GDS records an initial ticketing arrangement entered by the agent.
- Airline sends its deadlineThe airline's system calculates a time limit from rules such as booking class and days to departure, and returns it to the PNR, commonly as SSR ADTK.
- Check the fare rulesThe agent compares the airline deadline with the fare's advance purchase rule and works to whichever is earlier.
- Ticket or releaseThe agent either issues the ticket before the deadline or cancels the booking to release the seats.
- Automatic cancellationIf neither happens, the airline cancels the unticketed segments and may queue the PNR back to the agency.
Ticketing time limit in practice
Verified airline practices, as published in their agency guidelines:
- Cathay Pacific sends the time limit in an SSR ADTK message. If the booking is not ticketed, it is cancelled automatically at the ADTK date and time and the segments change to HX. A deadline that falls on a weekend is moved back to the previous working day.
- Qatar Airways assigns time limits by booking class and date range, factors in local weekends, and cancels the booking if it is not ticketed when the time limit expires. Bookings made within five days of departure are exempt from the automated time limit.
- Finnair notes that segment, fare and stored-fare time limits may differ and that all should be checked.
Who uses it
Advantages and limitations
Advantages
- Gives agencies a defined window to collect payment before committing to a ticket.
- Returns unsold seats to inventory, which supports fair availability for all sellers.
- Automated cancellation reduces the number of abandoned bookings in airline systems.
- Clear deadlines help agencies plan ticketing workload.
Limitations
- Deadlines vary by airline, fare and market, and the fare rule and airline time limit can conflict.
- Close-in bookings can have very short time limits, sometimes only hours.
- Missed deadlines mean lost seats and possibly a higher fare on rebooking.
- Attempts to extend time limits by rebooking can result in airline penalties.
Frequently asked questions about Ticketing time limit
What does SSR ADTK mean in a PNR?
SSR ADTK is an airline-generated service message that tells the agency the date and time by which the booking must be ticketed. Airlines such as Cathay Pacific use it to communicate their time limit. If no ticket is issued by then, the airline normally cancels the unticketed flights automatically.
What happens if a booking is not ticketed by the time limit?
The airline usually cancels the unticketed segments and releases the seats back to inventory. Cathay Pacific, for example, changes cancelled segments to HX status. To travel, the agent must make a new booking from current availability, which may only be possible at a higher fare.
Which deadline applies if the fare rules and airline time limit differ?
Work to the earlier one. The fare's advance purchase rule and the airline's own time limit are separate controls. Qatar Airways states that when the fare rules set a ticketing deadline, the more restrictive deadline applies. Missing either can lead to cancellation or a fare that no longer applies.
Can a travel agent extend a ticketing time limit?
Not on their own. The deadline belongs to the airline, so any extension depends on that carrier's policy and must come from the airline itself. Cancelling and rebooking the same flight to get a new deadline is known as churning, and airlines such as Cathay Pacific treat it as abusive and may impose penalties.
