I assume the club don’t want to create a panic as they want to keep their most loyal customers happy aka the season ticket holders. It’s a pretty stupid way to run a business, risk pissing off your most loyal customers in the hope than someone’s neighbour might go to more than one match every few years.
Also, I’d imagine the ticket website would struggle to cope with everyone trying to buy tickets at the same time, United ain’t Ticketmaster!
The minimum points thing is getting boring now, the loyalty points system has been in place for over 20 years, there is no reason why an adult shouldn’t have at least 500 points over 20 years.
If they can’t be arsed to go to 3 or 4 matches over that length of time then they don’t really have any reason to complain about not getting a ticket.
Frankly I find it amazing that someone who clearly isn’t bothered about United would even care that they didn’t get a ticket!
