Does anyone have anything to add on the topic of the Manchester to London fare in question?
I'm not quite sure what you are asking or how you'd measure it; if you defined your request exactly it may be possible for someone to query the fares database and produce a report. This would be best done in a new thread.Sure, my question was after eliminating the most obvious raids how many TOC-specific flexible fares are left which would need a strategic descision on whether it was appropriate to retain them? are we talking tens? hundreds? thousands? more?
There are around 6 million origin/destination pairs on the railway, but afaict the vast majority of them do not offer TOC specific fares.
