If a group of our excellent moderators are having ticket problems when travelling with FGW▸ , just think of the effect on the ordinary/occasional traveller.
I'm not so sure ... we read stories of newcomers to rail travel being horrified at prices - I recall a Bath to the north east example which made the press a while back, and the 1000 pound fare from Newquay to Kyle of Lochalsh. And such newcomers will tend to get a more flexible and more expensive option than they need. Witness the Consumer Association tests which result in valid tickets being sold, but not the lowest cost valid ticket for the journeys being made.
For two trips Melksham to London, and three trips Melksham to Farnborough the other week I was initially quoted over 700 pounds when I looked it up on line. A phone call to the FGW number / put through to National Rail gave me an alternative of about 430 pounds. And experts here found a valid solution at 243 pounds. At the cost of a really dirty look from one
SWT▸ gate attendant, and another asking me where Melksham was. I would have avoided the question (perfectly acceptable) and dirty looks (which are poor customer relations) if I had gone for one of the higher priced options.
So ... I contend that the newcomer is far more likely to pay more / far more than he / she needs, rather than hitting issues such as those of who are able to choose some of cheaper, valid, but less known alternatives.
