Had a travel clerk (civvie) at ISK's companion statement who said I had underclaimed for travel to a railway station. I had not claimed the journey Mrs PN made home or to collect me a few days later.
Checked QRs, sure enough the double journey was mentioned but specifically for airports. No sweat, this star then went back through my claims for the previous 3 years, including at ISK, and we re-submitted.
Not content with that, she then recalled the years 4-6 from archives and we worked through them as well.
A star.
