Mr. TK must have a surname starting with A to always get 001.
That might be the case for NZ, my SEQ 001s were on TG 20+ years ago… and as I noted upthread, airlines seems to use this field slightly differently. Surname is pretty middle of the road alphabetically as well 😎
Best from e-BPs that I can find is SEQ 002 from HKT-BKK Sep 2019
