London-Midland style booking engines think NUN-COV-EUS is valid for this fare. Virgin-style booking engines restrict to NUN-RUG-EUS (although the latter regularly tries to charge the Any Permitted fare for routeing directly to RUG, so can't be trusted).
It seems as though some engines take "route direct" in this case to mean "not via BHM", whereas others take it to mean (more logically) the most direct route (although it does allow travel via NMP, so not always the most direct!).
I've always assumed the latter interpretation was correct. However the discrepancy has persisted for a number of years now, so I'm wondering if in fact the former interpretation was intended after all.
Anyone know?
