A method for improved management of an airline inventory during a service disruption is described. The method comprises receiving, at a mirror of a legacy inventory system, one or more updates from a re-accommodation system. The mirror is populated with the one or more updates. The method proceeds with communicating the one or more updates to the legacy inventory system at a controlled rate. The one or more updates communicated to the legacy inventory system are flagged as pending update. A confirmation that the one or more records are updated in the legacy inventory system is received. The confirmation indicates synchronization of the mirror and legacy inventory system. In response to the confirmation, the one or more updates are unflagged in the mirror. Statistical evaluation of the inventory is provided based on the one or more updates in the mirror.
