Ticketing Time Limit (TTL) Explained for Travel Agents
A ticketing time limit (TTL) is the deadline by which a held booking must be ticketed. If the ticket is not issued by then, the airline cancels the seats automatically. The airline sets it from the fare, the booking class, the route and how close the flight is, and the strictest limit that applies is the one that counts.
Key points
- The airline's deadline is the one it sends to the PNR (Passenger Name Record), often as an SSR ADTK line. Your own reminder date is not the deadline.
- Read the fare rule too. If it sets an earlier ticketing deadline, the earlier one wins.
- When the TTL passes, the segments go to HX (cancelled). You must rebook at today's availability and price.
- A hold protects the seat, not the price. Reprice before you issue.
- Cancelling and rebooking to get a new time limit is churning, and airlines charge for it through ADMs.
- In Bangladesh, a February 2025 ministry circular, as reported, requires passport details on every booking and cancellation of unticketed bookings after three days. Check how airlines apply it today.
What is a ticketing time limit?
It is the date and time by which a ticket number must be issued and sent to the airline for a reserved booking.
Cathay Pacific's ticket time limit FAQ for agents defines it as "deadlines for tickets to be issued." It adds that the deadline is "calculated from the PNR creation date and may be changed upon booking adjustment." Lufthansa Group's booking and ticketing policy (June 2026) calls it the "date and time by which a ticket must be issued."
Airlines use TTLs to stop seats being held without a sale. Cathay's FAQ says held seats without tickets cause "seats blockage," which hurts other customers and agents.
How do airlines and GDSs set the TTL?
The airline sets it, and the GDS (Global Distribution System) or airline system delivers it to your booking. Several limits can apply to one PNR:
| Source of the limit | Where you see it | Who sets it |
|---|---|---|
| Airline ticketing deadline | Often an SSR ADTK line. Some airlines send Amadeus users an OPC element instead. NDC and airline systems show it in the booking | The airline's revenue system |
| Fare rule advance purchase | The fare rules (advance purchase / ticketing section) | The fare filed by the airline |
| Price guarantee | The stored fare in the PNR | The airline and the GDS. Can be shorter than the seat hold |
| Your own reminder | Your PNR ticketing field or queue | You or your portal |
| Local regulation | Bangladesh: the 2025 ministry circular (see below) | The government |
A few rules from airline policies:
- The strictest one wins. Lufthansa Group says that if the system time limit and the fare rule differ, "the most restrictive limit applies." Cathay applies the most restrictive rule across all confirmed segments.
- Limits differ by booking. Lufthansa says they "may vary by RBD, office ID, origin and destination." RBD is the booking class.
- They can get shorter. Bookings made close to departure often need ticketing within hours. Cathay says some periods need early ticketing "to reserve seat for genuine demands."
- Weekends do not extend them. For Cathay, a deadline that falls on a weekend moves to the previous working day.
- The price can expire sooner. Finnair's ticketing time limit page says that in most markets its price guarantee lasts until "the end of the booking creation day," and that it is independent of the TTL.
Low-cost and direct-connect airlines often allow short holds or none at all. Some fares are "instant ticketing only."
How do you read a ticketing time limit in a PNR?
Look for the airline's message in the SSR or OSI area, then check the fare rule. A typical Cathay message reads:
ADV TKT NBR TO CX BY 16MAY 0200 GMT OR SUBJECT TO CANCEL
Read it like this:
- "ADV TKT NBR TO CX": advise the ticket number to the airline (CX), meaning issue the ticket.
- "BY 16MAY 0200 GMT": the deadline. Note the time zone. 0200 GMT is 08:00 in Dhaka (GMT+6), so a booking "due on the 16th" is actually due early that morning, Bangladesh time.
- "OR SUBJECT TO CANCEL": the airline will cancel unticketed segments after that time.
Then open the fare rules. If the advance purchase section says, for example, "ticketing within 24 hours after reservation," and that is earlier than the ADTK time, that is your real deadline.
On multi-airline itineraries, each airline may send its own deadline. Work to the earliest one. Seats, bags and other extras sold on EMDs (Electronic Miscellaneous Documents) can have their own deadline. Lufthansa says this "does not necessarily match the ticket time limit."
What happens when the ticketing time limit passes?
The airline cancels the booking. Cathay's FAQ says "the flight sector/s changed to HX," with an SSR message such as "CANCELLED DUE TO EXPIRED TICKET TIME LIMIT." It adds: "you will need to create a new booking from current availability."
Other points from airline policies:
- Partly ticketed bookings are split. Lufthansa says that in a PNR with several passengers, "the PNR will be split and unticketed names cancelled."
- Fake ticket numbers do not work. Lufthansa treats them "as an attempt to bypass TTL." It also checks voided and refunded tickets, which "will lead to cancellation of active segments."
- Clean up after cancellation. HX and other inactive segments left in the PNR can themselves lead to ADMs (Agency Debit Memos, airline charges to the agency).
Bangladesh: the 72-hour rule
On 11 February 2025, the Ministry of Civil Aviation and Tourism issued a circular aimed at ticket hoarding. As reported by The Financial Express:
- every booking, including group bookings, must carry the passenger's name, passport number and a passport copy;
- if the ticket is not issued in the passenger's name within three days (72 hours), the booking is cancelled automatically.
A January 2026 ordinance amending the travel agency law also listed false bookings as grounds for action against an agency, but it has ceased to have effect, according to the official Laws of Bangladesh website. Check how each airline applies the 2025 circular, and confirm the current rules with the Ministry of Civil Aviation and Tourism, before you rely on a hold longer than three days.
What are the risks of holding a booking?
| Risk | What happens | How to avoid it |
|---|---|---|
| Fare change | The price is not guaranteed until issue. The fare, taxes or exchange rate can change, or the class can close | Reprice just before issuing and confirm the amount with the customer |
| Auto-cancellation | Missed deadline, segments HX | Diary the earliest deadline in Dhaka time. Collect payment early |
| Churning ADM | Cancel and rebook to get a new limit | Do not do it. Cathay calls it "abusive behavior" and may charge an ADM or cut inventory access |
| Duplicate booking ADM | Holding the same passenger on two PNRs or systems "just in case" | One active booking per journey. Cancel the extras |
| Fictitious booking ADM | Holding seats with dummy names for expected demand | Book only for real passengers, with names as on the passport |
| High cancellation ratio | Many holds that never ticket | Hold only for customers likely to buy. Some airlines, such as US-Bangla, charge for a high cancellation ratio |
Lufthansa defines churning as "cancelling and rebooking of the same reservation... across one or more PNRs or GDS/CRSs" and calls it "strictly prohibited under any circumstances." Read our guide to ADMs and how to avoid them.
Good hold practice: a checklist
- Book with full names exactly as on the passport, and the passport details.
- Read both the airline deadline and the fare rule. Note the earlier one in Dhaka time.
- Tell the customer the deadline and the price in writing, and say that the price can change until issue.
- Collect payment before the deadline, not on it.
- Reprice and issue. Check the ticket number is in the PNR.
- If the customer drops out, cancel the booking promptly and remove HX segments.
- Never cancel and rebook to stretch a time limit.
If plans change after issue, see our guide to void, refund and reissue.
How Ticket Lagbe shows hold and issue time limits
On Ticket Lagbe you can hold a booking, then issue it. The time limit is shown for each fare, so you can see how long you have before you choose.
- Issue Now fares: some airlines and fares are instant-ticket only. These are marked "Issue Now" instead of offering a hold.
- Hold reminders: the portal sends reminders about held bookings. Flight change notices tell you when the airline changes a booking.
- Rules before booking: each fare's fare rules and baggage window shows the refund and change conditions before you hold.
- Partial payment: on eligible refundable fares, by airline or supplier rules, you can pay part now and the rest before the due date.

Frequently asked questions
What is a ticketing time limit in airline booking?
It is the date and time by which a ticket must be issued for a held booking. If no ticket number reaches the airline by then, the airline cancels the reserved seats.
What happens if the ticketing time limit expires?
The airline cancels the unticketed segments, usually showing them as HX, and sends a cancellation message to the PNR. To travel, you must make a new booking at the current availability and fare.
Is the time limit I put in the PNR the airline's deadline?
No. A ticketing date you or your system enter is a reminder for your own office. The airline's deadline is the one it sends to the booking, often as an SSR ADTK message, and the fare rule may set an earlier one.
Can I extend a ticketing time limit by cancelling and rebooking?
No. Cancelling and rebooking the same seats to get a new time limit is churning, which airlines treat as abuse and can charge for through ADMs. Issue the ticket, or let the booking go.
Does holding a booking guarantee the fare?
Usually not. A hold keeps the seat until the time limit, but the price is generally guaranteed only for a short period or once the ticket is issued, so reprice before you issue.
Is there a 72-hour rule for bookings in Bangladesh?
A February 2025 circular from the Ministry of Civil Aviation and Tourism, as reported by The Financial Express, required passport details for all bookings and automatic cancellation of bookings not ticketed in the passenger's name within three days (72 hours). Check with each airline how it applies the rule today.
