I have an Annual Gold Card as a result of my Adult Annual Travelcard (Zones 1-4 Oyster). Travelling from Gatwick Airport to London Victoria on Wednesday evening of last week with my wife, I bought two Adult single tickets (on Southern, NOT Gatwick Express). The seller would give me the 1/3 discount only on my own ticket, and not also on my wife's. He was adamant about this. Is this correct? I understood that the discount could be applied to up to three other adult tickets, travelling with.
