More than 3,500 tickets were yesterday snapped up as Pompey fans booked their play-off presence.
Seats for the home tie of Pompey’s semi-final against Plymouth have now gone on sale.
The Blues have still to learn which of the two scheduled dates will see Fratton Park stage the two-legged contest against Derek Adams’ side.
Yet that didn’t prevent supporters yesterday buying tickets on a busy opening day for the ticket office at Frogmore Road.
Lengthy queues gathered for the 10am opening and the club reported a brisk trade throughout the day.
Season-ticket holders and Trust shareholders have until 8pm on Sunday to purchase their seats.
Those wishing to secure their seats in person can visit the Frogmore Road ticket office or the Fratton end booths from 10am to 5pm until Friday.
They can also be bought at Fratton Park before kick-off against Northampton on Saturday – and until 6pm after the final whistle.
In addition, The Quaytickets call centre will be manned by 40 staff seven-days-a-week, open from 9am to 8pm.
Those wishing to order by phone can call 0333 320 0750.
General sale of tickets will then begin on Monday, May 9, from 10am.
Tickets are priced at £20 for adults, £15 for seniors (aged 61 plus), young persons (17-22) and £10 for wheelchair spaces and unaccompanied juniors (under-17s).
Pompey have their final match of the League Two campaign on Saturday. If they finish fifth, Fratton Park will stage the second leg on Sunday, May 15 (6pm).
Should they claim sixth spot they will be at home for the first leg on Thursday, May 12 (7.45pm).
