The aim is that all elements in a PNR have the status HK, which stands for OK.
By updating the status of (flight) elements in a PNR, there is communication between the airline and Travix, most of the times in case of an Airline Schedule Change.
The airline informs us by changing e.g. a flight status from HK into TK.
After the customer is informed and has agreed, the PNR needs to be updated in order to inform the airline.
In one entry, both flight segments and general fields (SSR’s) will be updated:
Entry in Amadeus: ERK
Entry in Worldspan: EWGR
