Duplicate PNR
Duplicate PNR — is two or more bookings made within a time interval set by a carrier, that contain a list of matching passenger parameters, and may be qualified as bookings of the same passenger. Such bookings are considered as duplicating, if withing the specified time period one passenger may only perform not more than one flight.
- Duplicate bookings departing from one city — two or more bookings of one passenger with departing within specified time period from one city .
- Duplicate bookings departing from nearby ports — two or more bookings of one passenger with departing within specified time period from ports classified as nearby.
You may manually set a time range for departure within one city and distance between ports that are to be classified as nearby ports in the system.
The match analysis is held by matching surnames in PNRs along with one or several following parameters match:
- Name
- Initials
- Patronymic
- Date of birth
- Document data
- Contact data
- Loyalty card number.
Depending on which criteria match in the PNRs, there are three Duplicate criteria groups differing by match exactness:
- Max (maximum) – for the most exact matches
- Mid (middle) – for the medium exact matches
- Min (minimum) – for the less exact matches.
Each parameter should be included into one or several criteria set.
Flight route is analyzed, too: PNR with routes that cannot be flown are considered as duplicate.
Example 1:
| 1 | Michael Bohn | 13.08.72 | Paris – New York | ХХ-123 | 25.07 | 10.00 |
| 2 | Bohn M. | 13.08.72 | Rome – Lisboa | ХХ-456 | 25.07 | 17.00 |
May be considered as duplicate, as the passenger is not likely to travel from New York to Rome within less than 7 hours. If such PNRs are found, then airline dispatcher will decide which of them are to be canceled.
Example 2:
| 1 | Michael Jackson | 13.08.72 | Arlanda - Frankfurt-am-Main | ХХ-789 | 25.07 | 10.00 |
| 2 | Bohn M. | 13.08.72 | Bromma - Frankfurt-am-Main | ХХ-890 | 25.07 | 15.00 |
May be considered as duplicate, as Arlanda and Bromma airports are located in Stockholm not far from each other. The passenger is not likely to travel to Frankfurt-am-Main and back to Stockholm. So we can assume that the passenger was trying to find a ticket at lower cost, or didn't know exact time when he can depart, so they booked two tickets.
