A couple of weeks ago I travelled SOT - EUS on a 1st Advance, walked to St Pancras and asked the gate attendant if a Stoke - London Terminals ticket was valid for onward travel to Elephant & Castle. Without a second thought he said yes, and opened the gate for me.
Subsequent research suggests Elephant isn't officially a London terminal station, though other Thameslink through stations appear to be. I repeated exactly the same journey today and asked the man at the gate, and he said I needed to use Oyster for onward travel - which I did without question.
Obviously I'm not going to travel illegally, but nor do I want to pay unnecessarily. Please could someone advise what's correct? Many thanks.
