Something which I have seen mentioned in various posts and elsewhere (it is marked as such on the CTR keyGo map: https://www.thameslinkrailway.com/-...documents/gtr-1805-ret-keygo-area-map-v27.pdf) is the 'London Travel Area' - but what I have been unable to find is any definition of it, saying what is (and is not not) in it.
While I have the impression that it is related to the TfL Oyster/Travelcard Zones, or Greater London area, I would like an exact definition, as to what it is, and what its purpose is.
Can anyone elucidate, or point me at an official source?
