@Didsbury Dave has always been our resident expert when it comes to FA allocations, and will no doubt have to explain this many more times before the count is done.
Very roughly, this is how they do it. They hold back a number of tickets, maybe 10,000 for an FA Cup final and 3 or 4000 for a Carabou cup final, half in each end. This covers all of the member clubs, right down to grass roots levels, who are contacted and offered a number of tickets. A premier league club might be offered 10, a non league club 4, I don’t know the breakdown.
These clubs elect to take these tickets or not but when they do they can select how many and which end they are in. So the FA don’t know what the take up will be until the application deadline.
I’ll use the example of the Stoke final. The member clubs ended up requesting , say 5000 City end tickets, and 2500 Stoke end tickets. This meant that 2500 stoke end tickets, in their normal allocation sections , were given to Stoke as an “extra allocation” but none given to City. Yet On the day both clubs had the same amount of tickets.
I did once work out the exact numbers but I’ve forgotten. It’s not hard. It’s why we get a much bigger initial allocation of tickets for charity shields and semifinals and a smaller one for the FA Cup finals, yet on the day we always have the same number of fans.
I think that over the last 10 years or so the number offered to clubs has been reduced hence increased “allocations” for FA cup finals in particular.
I hope that’s clear to everyone. Basically, if you take out the cooperate sections which are mixed, each team always has around 36,000 seats. The numbers I’ve used here are approximate but close.
