In this lesson, you will learn about the following options on the Travel Configuration page:
- Enable Churn Detection
- Airlines on which to track and prevent churning
- Enable Duplicate Detection
- Airlines on which to prevent duplicate booking on the same date
To access these settings on the Travel Configuration page, use CTRL+ F to search for each of them as depicted in the following graphic.

Hint
Enable Churn Detection
Churning is defined on airline websites as canceling and rebooking the same itinerary in the same or different classes of service across one or more PNRs.
When you enable the Enable Churn Detection setting, Concur Travel will evaluate all flights booked for the same user over the last 31 days when making the "churning" determination. Review the following scenarios to learn more about the setting and its behavior:
- The third time the user tries to book the same flight in the same class of service; Concur Travel warns the user that this is the last opportunity to book it
- The fourth time the user tries to book the same flight in the same class of service; Concur Travel prevents the user from doing so
- The fourth time the user tries to book the same flight regardless of class of service; Concur Travel warns the user that this is the last opportunity to book it
- The fifth time the user tries to book the same flight regardless of class of service; Concur Travel prevents the user from doing so
Note
In the Airlines on which to track and prevent churning field, you can add one of the following options:
- A comma-separated list of airlines (up to 10; example: AA, BB, CC)
- ALL to enable it for all airlines
Enable Duplicate Detection
The Enable Duplicate Detection setting turns on system checks that look for overlapping or duplicate reservations already held by a traveler (air, hotel, car) when they try to make a new booking. When enabled, Concur Travel compares the new itinerary against the traveler’s existing trips (from the Trip Library and agency/GDS PNRs synced to Concur) and does the following:
- Flags potential duplicates (for example, a second flight on the same dates, a hotel covering the same nights, or a car rental overlapping the same period)
- Displays a warning (and depending on your configuration, may require an override reason or block the booking altogether)
This helps prevent unintended double bookings, agency debit memos, and additional costs.
Caution
In theAirlines on which to prevent duplicate booking on the same date field you can add one of the following options:
- A comma-separated list of airlines (up to 10; example: AA, BB, CC)
- ALL to enable it for all airlines
