I am mildly flabberghasted by the info revealed on this thread.
For the past 6 months, I have been commuting from Brighton to Warren Street Tube, via London Victoria.
I've been using Monthly season tickets (standard class).
Initially I was very confused about what ticket I should buy as the Southern "mixing desk" website brought up such a confusing variety of fares.
I actually had to ring up their Customer Services and had to spend the best part of half an hour asking them to explain the selection.
I was particularly confused by why they appeared to be selling "Brighton - London Zones 1-6 (Thameslink only)" tickets (£393.30) compared to "Brighton - London Zones 1-6" (Any permitted route) (£503.50)
"But no Thameslink trains go to Victoria?" I asked. "That's right".
"So the £393 ticket isn't valid for going to Victoria" "No, it isn't".
"So why does the website bring it up in the search results?" "I'm not sure, sir! lol"
I usually get the 07:12 BTN to VIC Gatwick Express service each morning.
Regularly, the conductor will announce "Tickets market 'Thameslink only' are not valid on this service. If you are in possession of such a ticket, please alight from the train and proceed to platform No.5, where you'll find your next Thameslink service departing at blah blah..."
From what I read on this thread (and the links to supporting documents seem to support it 100%), I have been completely duped by Southern, and a 'Thameslink only' ticket was valid on my route.
For the past 6 months, I've paid about £110 too much for my ticket!
I'll bet literally hundreds of thousands of others have too. This could be the next PPI!
I'll be writing to Southern requesting a refund of the excess, and escalating to Passenger Focus if I don't get satisfaction. I'll also be writing to my MP Caroline Lucas.
I dare say the local press will be interested too.
