Premier League clubs have unanimously agreed to continue the £30 cap on away ticket prices for the next three years.
The measure was introduced for the start of the 2016-17 season and will now run until the end of 2021-22.
A Premier League statement said: "All clubs know the crucial importance of away fans in generating the best possible atmosphere at matches.
"Clubs recognise the additional travel costs often involved when following a team away from home."
The statement added: "For the last four consecutive seasons, Premier League crowds have reached record levels with 96% of tickets sold.
"This is testament to the compelling football and dedication of fans, and the league is committed to maintaining these high attendances."
