I'm trying to change the date of a return journey from Paddington to Hereford. I've booked the outbound and return journeys separately. The current outbound journey requires 1 change i.e. PAD to Newport; then Newport to Hereford. However, if I try to change the date of the journey then every alternate date I select requires 2 changes i.e. PAD to Reading; then Reading to Newport and finally Newport to Hereford. If I try to make a completely new booking on one of the alternate dates then a 1-change journey (going through Reading) for the same price as my current advance ticket is possible. The same applies to the return journey i.e. forcing me to get off a "fast Paddington" train at Reading to wait approx 20 mins for another one. Is this a deliberate policy by FGW to make it a hassle (as well as the understandable admin fee) to change the dates of advanced tickets?
