PNR data is parsed from GDS air file and written in Travelwise database by a program called TAIR-Reader (Travel Agency Inferface Record Reader).
PNR data is displayed in multiple places.
In this document airfile syntax is illustrated basing on the following airfiles mainly:
4427M6 (Amadeus), MQ3W9C (WorldSpan) and EMMUXV (Sabre). Look at PNR TEXT for full text of
these airfiles.
If any other examples are used then corresponding PNR numbers are written in brackets.
