Travel agents insert a retention line into a global distribution system to keep an itinerary active past its normal expiration date. Booking systems automatically archive or purge records after the last active travel segment concludes. By adding a future-dated pseudo-segment, agents ensure the record remains accessible for accounting, refunds, or future modifications.

Add a retention line for December so we can process the unused ticket exchange later.
Insider tip
Always remember to cancel retention lines once the accounting is finished, or they clutter the agency queue.
