Why was it a mistake? Hopefully not because it has it has reduced the cost of travel on various Northern journeys.
Maybe, but if we assume people can see further ahead of them than the end of their nose, anyone who realises
- the flexible fares are (to some extent) regulated; and
- the inflexible Advance fares are completely unregulated; and
- the LNER Opaque Fares scheme, as well as the widespread removal of off-peak day singles
and returns for local journeys on Northern's patch, demonstrate the intention is to withdraw all but the very worst value flexible fares (and probably ultimately to withdraw those as well), at which point the unregulated fares are liable only to continue to be cheaper than the regulated fares used to be for approximately three nanoseconds;
would surely appreciate that it would be better to have a bit of transparency over fares.
It is politically quite difficult to put up regulated fares by more than a few percent a year on average. There are no such constraints on unregulated advance fares because the media can't find out, so can't report, how much the fares have gone up by over time and there's no media-friendly annual round of fare increases.
