When they got their ST doesn't matter a jot.
There were plenty who got ST's in the Broomloan Rear once the boycott ended in 2015 and Warburton took over.
Me and SDF Jr were two of them. We were lucky enough to get a move elsewhere to guarantee him a Celtic ticket(only adults in the Family Section were offered them pre 2018).
There'll be plenty of them still sitting their paying their money year in, year out that this is going to affect.
My pal has had 3 season tickets in the Family Section since 2015, their kid is now 20 and way above the juvenile age and Rangers can't move them elsewhere in the stadium because they don't have three seats together to offer them.
Now this decision is probably going to fúck them over if Rangers still can't give them three tickets together.
I get why some folk are happy but there will be a sizeable amount who will miss out, many of whom paid their ST happily during a pandemic to help the club. What a thanks this is.
