I started this last season, might resurrect the thread; my theory is still that season tickets will diminish steadily over time, an atiquated model of loyalty and affordability.
You have many 10s of 1000s on memberships that simply give you a 'chance' to buy a ticket and increasing levels of memberships up to 100s of pounds a year, that gone you a better chance. Pay more, get a better chance, with no actual ticket in hand yet.
Then you can flog tickets at high rates per capita, much higher than the season ticket average per match, and you could double (?) ticket income. Possibly more.
