I suspect that it will remain contradictory as it has been for years. We have two season cards, one I use and one that is used by my wife for weekend matches and my son midweek.
Because we are in the Senior category and my son is Adult, that requires an upgrade for every match he attends. Sometimes the upgrade is added to the card, sometimes a paper ticket is posted out and sometimes it is print at home. I have been unable to detect any logic or pattern in the choices.
The box office have been very helpful when issues arise. When City played Lyon in the Group Stages, I was travelling from Glasgow and he was coming from London. A gale blew down the wires on the line in Scotland and I was unable to get down to the match. That particular match had the ticket on a season card which I had. We phoned through and they issued him with a paper ticket at the office.
I await with interest how it will be dealt with now.
