OrderRetrieve service is used to retrieve live orders that have been created previously. In the response will appear only confirmed segments from retrieved order. This service also allows consulting NDC orders that have been modified outside NDC. Actually this service shows info when segments are the same quantity between original and updated order and when changes are refered to class, date or flight number. In this case a warning is shown an order is unserviciable. NDC Servicing operations for corporate will only validate that travel agency indicated in the request is the same as generated the order. If corporateID is present in the request, it will only be checked when the order has been generated with corporateID. |
