Reading are trying to get an agreement in place that would see all Championship clubs charge a maximum of £20 for visiting away fans.
But the Royals ' pleas have largely fallen on deaf ears so far with only three of their 23 peers agreeing to implement the strategy.
The club wrote a letter to every side in the second tier, which read: "For the 2022-23 season there will a marginal price rise to our ticket prices. We are very proud, however, that our matchday ticket prices remain amongst the most competitive across the Championship. Since 2016, we have championed Twenty’s Plenty and although we have now raised our prices above £20, your club will be given the opportunity to offer your fans £20 tickets when your team visits Reading next season…but only if you commit in advance to a reciprocal arrangement for our away fans not to pay more than £20 in the reverse fixture.
