Had the same problem when relocating because my Grandson got his ticket from the waiting list last year. Only way to,make sure you get a seat you won't is to go to the ticket office in person if that's possible. You can phone Supporters Services but usually takes ages and you won't see a seating plan, the web site is simple not fit for purpose it's the same one they used for years with a new front webpage, the club needs to invest in better more modern system its not that they haven't got the money!
