Introduction
KIU SNAPSHOTS (PNR) is a delivery service for PNRs that allows keep synchronized the status of all PNRs with the PSS in real-time. Every time a PNR is created, modified, splited, or purged, a JSON file will be sent with the affected PNR(s).
File Structure
The name of the JSON file has the prefix PNRS_ and the timestamp in UTC, following the pattern PNRS_YYYYMMDDTHHMMSSFFFZ.json. For example, PNRS_20230512T105030923Z.json.
Internally, the file contains an “event_details” object that provides details about the event that triggered the change, and a list of affected PNRs [1..n]. Each object in the array represents a PNR, and its structure is represented in the schema of the get_booking_information API (except the purge event).
Example File
{
“event_details”: {...},
"pnr_list": [
{
"record_locator_version_information": {},
"record_locator_information": {},
"passengers_information": {},
"flights_segment_information": {},
"flights_origin_destination_information": {},
"contacts_list": [],
...
},
{...}
]
}
Structure of event_details
The event_details object has the following structure:
Key | Data type | Possible values | Description | Example | Observations |
|---|---|---|---|---|---|
system_from | string(2:3) |
| C1 or airline operator code, depending on whether if its a PSS terminal or Kiu GDS terminal | Z8 |
|
company | string(4) |
| Unique code of the company, airline, or agency within Kiu | 00Z8 |
|
channel | string | HOST, GDS |
| HOST |
|
subchannel | string |
| In the case of GDS, it’s the own GDS code (C1, 1A, etc.). For HOST, is the value configured in the office table, command DNO / BI STAT.SUB-CHANNEL. | SALES OFFICE |
|
device | string(0:10) |
| Kiu device that generated the transaction | LPB00Z8205 |
|
agent | string(0:9) |
| Kiu device that generated the transaction | HDQ00Z8SM |
|
pnr_action | string | CREATE, MODIFY, SPLIT, DELETE | Identifies whether the event is a creation, modification, or split | CREATE | The SPLIT will apply to both PNRs (the newly created and the modified ones in that process). |
transaction_type | string | DIRECT, INDIRECT | Identifies if the modification to the PNR is a direct intervention by a user/API or an indirect one related to another process. |
|
|
origin | string |
| Identifies the origin that triggers the modification Related to the If it's DIRECT, this field could be:
If it’s INDIRECT, this field could be:
|
|
|
application | string |
| Detailed in "Source and Applications" |
|
|
timestamp | datetime |

Source and Applications
Since there are different scenarios where a PNR can be modified, the classification is based on the type of transaction - direct or indirect - the origin, and the application that triggered it.
Based on these variables, the following combinations are constructed:
Origin | Application | Agent | Description |
|---|---|---|---|
AGENT/WEBSERVICES | KIU_COMMAND / OTHER | The entity that generates the transaction | Processes of reservations, modification, splitting, saving, issuing and voiding, via commands or APIs
|
WEBSERVICES | OTHER | The entity that generates the transaction | Reservation creation, reservation modification, and reservation splitting processes via webservices (v1 and v2) |
FROM_EXTERNAL_MESSAGE | MESSAGE_PROCESS | KIUSYSTEM | Process of Creation, Modification, and Splitting of Reservations via TTY Type B/Type A messaging. In this case, the device will be that of the office configured for the host with terminal address 00. |
FROM_EXTERNAL_MESSAGE | PFS_PROCESS | KIUSYSTEM | Adjustments due to post-departure messages (PFS, PRL) |
FROM_EXTERNAL_MESSAGE | PRL_PROCESS | KIUSYSTEM | Adjustments due to post-departure messages (PFS, PRL) |
INTERNAL_PROCESS | KAM | The entity that generates the action in KAM | KAM management process (inventory PNRs)
|
INTERNAL_PROCESS | ROBOT_TIME_LIMIT | KIUSYSTEM | Robot time limit adjustments |
INTERNAL_PROCESS | VMOVE_PROCESS | KIUSYSTEM | Reservation changes with VMOVE command (reaccommodation) |
INTERNAL_PROCESS | VMTM_PROCESS | KIUSYSTEM | Reservation changes with VMTM command (schedule change), if the carrier has that function activated. |
INTERNAL_PROCESS | EXPIRED_ITINERARIES_PROCESS | KIUSYSTEM | Process for canceling expired active itineraries (those that have passed more than 40 hours since their flight date) |
INTERNAL_PROCESS | CONFIRM_WAITLIST_PROCESS | KIUSYSTEM | Automatic waitlist confirmation process |
INTERNAL_PROCESS | SCHEDULE_PROCESS | KIUSYSTEM | Reservation changes due to schedule change (reaccommodation) |
INTERNAL_PROCESS | SERVICES_AUTOMATIC_CANCEL | KIUSYSTEM | Process for canceling itineraries or SSRs due to expiration. |
INTERNAL_PROCESS | SSR_INVENTORY_PROCESS | KIUSYSTEM | Process for confirming/rejecting SSRs with inventory |
INTERNAL_PROCESS | SSR_AUTOMATIC_PROCESS | KIUSYSTEM | Internal process for creating/canceling SSRs (This process is used by the system when an action/command needs to automatically add SSRs to a PNR, for example: when web check-in is done for a flight managed in an external DCS, and the SSR needs to be added with the check-in data.) |
INTERNAL_PROCESS | FOP_VALIDATION_PROCESS | KIUSYSTEM | Post-validation process for online payment issuance (In this process, the validator may add remarks with errors from the process or, for example, a remark with a transaction reference) |
INTERNAL_PROCESS | SEAT_ASSIGN_PROCESS | KIUSYSTEM | Internal seat assignment process (This occurs, for example, with the current web check-in functionality where a default seat is chosen, and since it involves PRS, the PNR is modified.) |
INTERNAL_PROCESS | RECORD_LOCATOR_PURGED | KIUSYSTEM | PNR purge process |
| RECORD_LOCATOR_SYNCHRONIZATION |
| Synchronization process that generates snapshots of all active PNRs in the PSS. No modifications are made to the reservation. |
Purge
The PNR purge process can contain up to 1,000 PNRs in a single file. In this scenario, the key record_locator_version_information of each PNR will be provided, along with a copy of the PNR history at the time of the purge (equivalent to *H).

Recap
When this module is implemented, a RECAP process will be executed that will re-run the database, generating a snapshot of each PNR. In this scenario, there are no modification to the PNR; the event_details will only have the key "application": "RECORD_LOCATOR_SYNCHRONIZATION".
This RECAP functionality is included in the implementation cost. Any additional requests by the airline for re-execution of this process will need to be evaluated by the commercial department.
