UPDATE 05/08/2019: If you have tranferred into the new Block 21 or 13 of the Cricket Field Stand you MUST bring your current seasoncard with your old seats details, down to the ticket office and have it replaced with a new season card with your new seat details on.
You will not be able to access your new seats in Block 21 or 13 until you have done this, and received your replacement card in person.
Over the summer the Cricket Field Stand at Turf Moor has been through a refurbishment project, replacing the wooden seats in the away section with plastic seating.
