This issue has affected me and I'm currently trying to persue a refund from TFW or The Trainline.
I was stopped by TFW at Cardiff Central for having an invalid ticket, an 'ADVANCE CLWB 60' ticket which shocked me (bought from The Trainline app).My previous day outbound ticket worked fine and was scanned by two guards. My next day return ticket was also scanned by two train guards fine. Only at Cardiff Central was my ticket flagged as invalid by TFW staff at a temporary outside barrier system because of the evening large scale event. The staff member who stopped me explained that I'm one of dozens of people he had stopped that day for having 'CLWB 60' tickets when they were under 60.
To my knowledge, I did not select CLWB 60. I had never heard of CLWB 60, and since using the Trainline's app since 2021, I have never been ineligible for any type of ticket on the ticket search results page. All other age related discounts are either by manually choosing a Railcard or by choosing a child ticket, including other CLUB age discounts!
I crossed checked TFW and the Trainline booking systems. TFW app showed an advance ticket as CLWB 60. The additional information button for that ticket type does NOT mention 'CLWB 60', or anything related to being over the age of 60 for this ticket to be valid for the customer. The Trainline booking app, for the same day and time did not even show CLWB 60 as an available ticket type.
National Rail's page showing discounts for advance tickets only mentions discounts for children or Railcards, both of which I would have had to manually select pre clicking search for tickets.
This 6 day only sale for which I was ineligible to take advantage of (because I'm not over 60 and couldn't pretend to be) has caught out dozens of people. It's a mess, a scam, and I'm not backing down until I'm refunded, either for my original ticket cost from The Trainline, or my on the spot ticket (£58.90!) from TFW. Personally, I think TFW should refund me, as they have created this monster.
I'm furious.
I have many screenshots as evidence of this mess which I'm using to fight my case. The offer expired yesterday so it is no longer searchable.
I really appreciate the discussions on this subject here. Thank you.
