Not sure how buying a ticket before someone else is the fairest way. For example, a person starts a shift with the emergency services as the tickets went on sale, comes home exhausted, goes to bed then goes straight on shift again without getting a ticket. Ok I’ve gone for an unlikely but possible scenario but why should someone who is furloughed and doing nothing but sitting waiting on tickets going on sale have priority access? There will be others who for one reason or other couldn’t buy straight away. Not sure their money has less value. Only fair way I can see is a ballot, where every season ticket holder has the same chance.
There will be complaints no matter how it’s done. Some non season ticket holders will probably complain at season ticket holders getting priority, they do for some cup game.
And I got my ticket early on the first day before I get accused of being selfish.
