For many other airlines that might be the case. I have had SEQ 001 before. Whereas for NZ it’s done alphabetically, if you try OLCI for yourself and others (with diff last name) on the same PNR at the same time you will see your numbers are vastly different, and always in the order or your surname initial alphabets.
