Tickets are on save only for season ticket holders, and those with 6 or more tickets stubs from home game this year.
Tickets for the home leg for ticket holders with 3 or more ticket stubs go on sale from 8am on Thursday, and any remaining tickets will go on sale on Friday from 8am.
The ticket office is remaining open to 8pm each night to cope with the huge demand, but still long queue's around the car park are expected.
Tickets for the away leg will go on sale on Wednesday 12th May to season ticket holders with season tickets starting with the code A, B, C, D & E. Tickets for all other season ticket holders will go on sale next week on Tuesday 19th May. No tickets will go on general sale as Brighton's away end only holds around 700.
