The current free travel concession will expire on September 30, for the majority of 16 to 18-year-olds, and those who are starting a new year of study need to re-apply at the Post Office to continue to get free bus and tram travel.

Anyone aged 16 to 18 and no longer in full-time education can continue to use their 16-17 Oyster photocard to travel at half the adult rate, or to buy half-rate Travelcard season tickets until the expiry date on the back on the card.
