Not sure though, because surely if you get a return on the 21 from Gateshead to Newcastle, you'd be able to come back on the 28/A, X1, X9/X10, X36 etc?
You can use it on the 28s, providing your not getting off on a part of the route that is only served by one service while you bought your ticket on the other. I think it might be best to ask a Chester driver though.
