Coleraine have already sold their allocation of 1,750 tickets and Crusaders have very few tickets left from their total of 1,300.
The decider is scheduled to be played at Ballymena Showgrounds on Saturday 28 January and the Irish FA is considering the possibility of installing extra seats.
"That is the preferred option and we are currently in consultation with the PSNI and Ballymena Borough Council," an IFA spokesman told UTV.
But the governing body has not ruled out switching the game to Windsor Park.
Both clubs agreed to the play the match at the Showgrounds but health and safety considerations and security procedures have restricted the capacity there.
