The Red Army snapped up more than 3,500 tickets on the first night of sale for the League Cup semi-final.
Aberdeen will face Championship Morton at Hampden on Saturday, October 22, at 12.15pm.
Tickets went on sale on Tuesday night to supporters with 80 or more loyalty points and were quickly snapped up.
Briefs will go on general sale for the Hampden clash on Monday (9.30am).
The Dons had expressed their disappointment that the semi-final was moved to an earlier kick-off to accommodate live coverage on BT Sport.
An official Aberdeen FC statement said: “12.15pm is a major disadvantage to our fantastic travelling support.”
Aberdeen Central MSP Kevin Stewart wrote to the SPFL chief executive Neil Doncaster, urging him to reconsider.
Boss Derek McInnes hopes the early kick-off time does not lessen the number of travelling Dons fans.
He said: “With the semi at Hampden we have to try to give ourselves a chance to get as many people to the game as possible.
“I don’t think a 12.15 kick-off allows that.
“Playing it at Hampden should allow everybody who wants to be at the game to be there.
“To try to get the biggest numbers in there, ideally the game would be at 3pm on a Saturday.
“Certainly not the early kick-off of 12.15.”
