If you have a season ticket it is compulsory to buy your seat for FA cup games and Champions league games. Failure to do do eg by not having an up to date credit card on the system to pay you are sent a reminder , failure to comply results in a one match ban of a league game.
The T&Cs. One way to guarantee the revenue for the club. ST cost, and 6 plus games so?
I remember reading an article, I think it was when compulsary purchase was introduced and fans weren’t happy.
Many fans (overseas) couldn’t make mid week games, when European and some domestic cup games were on. And it wasn’t as easy to pass on tickets, as it is now with the digital vouchers.
On reflection of what we have seen today, regarding the ticket scramble for Madrid, it’s only a sell out based on the compulsary purchase and ballot for remainder. Potentially many ST can’t make the game and there will be tickets available for resale. Not sure if that is the case generally with Cup games.
There certainly seemed to be a lot about for the Villa FA Cup game.
