Maybe the answer to this isn't known at this stage
With being able to transfer the ticket to a named person, do the club need to be made aware of this in advance, or is it sufficient that just someone on your list of 20 is using it?
Eg Man United game currently scheduled for 19th March. Will be moved to Sunday I'm sure, but if either are involved in the FA Cup at that stage, it'll be postponed to a later (likely midweek) date and I wont be able to go. So if I buy the ticket intending to go, do I then need to inform the club that it will be Dave on my friends and family list going instead?
