Yeah, I'm sure there'll be some complaints but if you are suffering last minute transport or similar issues 5/6 times a season, then you have bigger problems, presumably covered by the serious illness or other life events exemptions.
The email is ambiguous though. By my reading, they are saying that the seat has to be "utilised" 14 times but also that your eligibility will be reviewed if you don't "utilise" it for 5 games. Maybe they think there are 18 home games?
Also are they guaranteeing the exchange will be open for every game? Previously it only opened once the game was sold out.... (theoretically, I'm not sure they actually stuck to that).
There is also a loophole, of sorts, that if you forward it onto a member and they don't attend, that still counts as utilised. So if I can't attend and can't (for some reason) list it, I can forward it to a mate and it still counts towards my 14.
