Exactly. There's always going to be somebody that can't make it for whatever reason despite having committed to paying for a ticket and travel. An unintended consequence of this new system is that those that can't make the game can't offload their ticket to another fan and at least recoup some of their outlay. Your proposal for working round this is a good one because some fans will still travel without tickets and there could be some mileage in incorporating it into the ticket collection process.
