I agree with the general sentiment weeman, but if you'd encountered the Luton fans we did after that playoff match, you'd be ecstatic to see them relegated.
In your scenario, you are ugrading the ticket to a different category, but I don't think the OP wants to do that. They just want to move to a different place for a particular match, which in my experience can be done without any extra charge. I don't think it can be done online, but by...
Pretty sure it's not possible online, but can be done on the phone or in person. You get issued a ticket for the new location to use instead of your Season Card. Not sure whether there's a rule about having to buy another ticket.
It's good to see us near the top of that table, but for context you'd need to see much further down the list. If the vast majority of clubs are above (say) 80%, being on 86% doesn't make that much difference.
Wasn't Josh said to be playing through an injury? Hope that's not what caused this.
Regardless of that, I find it ridiculous that Sheaf gets panned for being too soft when he misses games. If you have an injury that needs to be protected, it's crazy to try and be some sort of hero.
