Ticketing Time Limit
The exact deadline set by an airline revenue management system by which a held reservation (PNR) must be ticketed, otherwise the reserved seat inventory is automatically cancelled by the airline.
Real-World: An airline PNR may display 'TKT/TIME LIMIT BY 14OCT 23:59'. If payment or ticket issue does not occur by that timestamp, the airline robot sweeps and releases the seats.
- Enforced by automated airline inventory robots (e.g., Sabre Robot / Amadeus Queue Sweeper).
- Allows visa applicants and travel agents to hold confirmed seats without immediate non-refundable payment.
- Varies based on flight departure date, fare class, and airline booking rules.
