Re X24:
Arriva did release a statement a few months ago which said that Teen Cards were valid on the X24 service.
I remember saying on the forum at the time it was clearly to compete with the X22, which attracts a large number of Get Around 90p single fares.
With hindsight, this may have only been over the Christmas period?
