North-east football supporters clubs have raised fears over the potential for crowd trouble at the match.
Both Aberdeen FC and Rangers fan groups said there could be problems due to both semis being played at the same stadium on the same day – one kicking off at noon and the other at 7.45pm.
Amanda Barber, chairwoman of the Pittodrie Bar Supporters Club, said it would be an “absolute nightmare” for fans.
She added: “I wouldn’t be surprised if there’s trouble.
“It’s the first time we’ve played Rangers at Hampden since they became a new club and we’ve got Hearts and Celtic coming in at the same time as we’re coming out.
“It’s not just Aberdeen fans that are complaining. It’s Hearts and Celtic and Rangers as well.”
Kevin Niven, who runs the Granite City Rangers Supporters’ Club, said: “I envisage problems arising for people leaving the area late and public transport will be an issue. Trains from Central Station to and from Hampden will be a flash point.”
A Police Scotland spokeswoman said: “We are aware of the SPFL’s decision to schedule both semi-finals on Sunday October 28 at Hampden Park.
“Police Scotland is extremely experienced in policing multiple football matches and major events.
“Our planning is already well under way and both matches will be policed appropriately.”
