We used 6 adult and 2 oap to get 7 adult and 1 oap today. Reason one oap getting adult is oap may not be able to go due to health so prepared to pay more to give option to pass on.
Discrepency over OAP age, at City it's 65 so a BFC OAP 60-64 would technically have to buy an adult ticket as not to compromise themselves and the fascists at Maine Road, or whatever they call their ground nowadays.
