The current limit was set to expire at the end of the current campaign, three seasons after it was brought in,
But with Premier League officials meeting with shareholders tomorrow, it is expected they will recommend the cap stays in place for another three years.
It would take a 14-6 vote to block the extension of the limit beyond the 2018/19 season.
The £30 cap was introduced as fans grew increasingly frustrated with the rising cost of seeing their team play away.
As a result, the number of fans trekking around the country was falling until March 2016 when the Premier League introduced the cap.
Since then, figures have started to pick up again with the average away support now around 2,300.
The Premier League are set to tell their clubs scrapping or increasing the £30 limit would damage the league's reputation.
However, The Times believe some clubs have privately questioned sticking with it.
It is the first test of unity the Premier League has faced since former executive chairman Richard Scudamore's departure.
A spokesperson for the Football Supporters' Federation told the Mail: "There had been a rapid rise in away ticket costs for many supporters and the cap put a halt on that.
"However, we still believe more can be done and we call on the Premier League to look at ways to further reduce concessionary ticket costs and subsidise travel costs when games are moved for TV."
The average attendances at Premier League games this term are close to last season's record of 38,255.
