If you don't renew at the frozen price by 15th June, how long do you get after that to purchase before the seat is made available to the public? I'm thinking June's salary you see........
Just having a look at my renewal forms today. It doesn't give a 'final' closing date. It says they are unable to guarantee the renewal of applications received after the 15th. I reckon they'll try to contact you after the 15th and just sell the ticket to someone on the waiting list if you don't reply.
