The Club's coming Fan ID scheme (the amnesty) is to get the right name on every ticket. This will include those who have inherited them and being using them for sometime. It will also allow users of tickets to get their name on them where the current owner agrees that they can take the ticket.
Currently there are an average of around 2000 seats empty at each home PL game.
It will see a number of people capable of being named to use the ticket during the season for an unlimited number of times in that season - this will allow people to take a season break if needed (work, illness, potless) or to allow STs to be shared.
The caveat will be that the ticket HAS to be used - if a season ticket (without proper explanation) goes unused during a season for a number of games the sanction will be the ST is lost.
The Club also plan to make recycling the season ticket easier and with the full value being credited back a few days after it goes back so it can be resold. This will help address the unused seat issue for ST. There will obviously be some times when the ST cannot be used (emergency on day of game or breakdown travelling etc).
The aim to increase the recycling can then lead to a stage two which can see some innovation with ticket prices as the number of available tickets increases above what there are now available to recycled by the Club.
