To clarify, this is on fares set by XC, not necessarily all XC-operated services.Avanti appears to set fares from Glasgow to Bristol and on to Totnes, XC sets fares to Plymouth and beyond.
From Edinburgh, XC sets fares to Cheltenham and beyond, and both XC and Avanti have fares to Birmingham.
From memory it took quite a while for XC fares to be removed from Avanti flows after the separation of the franchises (both Virgin initially).
Among other things, XC forces the blanket "not before 0930" off-peak time restriction which is not the same on Avanti.
