Alex Neil felt Preston North End supporters were charged too much for Saturday's clash with Leeds United.
An adult ticket was £39 if bought in advance, with the price rising to £44 at the Elland Road turnstiles.
Despite the high prices, 697 North End fans made the trip to West Yorkshire for the 0-0 draw.
But a number boycotted the first Championship away game of the season, preferring to keep the money in their pocket.
North End manager Neil said: "Our fans were fantastic, the fact that they got charged £44 a ticket was a disgrace to start with.
"The guys who did pay their money and came and backed their team, I hope they were very proud of the lads.
"If you are a family of four and are a normal working family, that is a a lot of money.
"I don't think it is necessary.
"We certainly don't charge away fans coming to watch their team that amount at our place.
"As far as I'm concerned, it is wrong, I'm unhappy."
Asked if there could be anything done from within the game, Neil replied: "They can bring their prices down, they can put it down to a normal level.
"We wanted to have as many fans through the gate as possible, now if the prices were different it might have added another 500 fans or something like, who wanted to watch their team.
"That didn't happen largely because the prices were too high."
When asked if North End had raised the matter officially, Neil added: "No, but I'm doing it just now. I'm quite happy to complain because I don't feel it is right."
Preston charge £24 a ticket for away fans in the Bill Shankly Kop at Deepdale.
