"People may expect us to win every away game but this was a valuable away point," Benitez said. "There are still eight matches to be played and as Huddersfield lost we are now in a better position than we were before the game."
The point leaves Gianfranco Zola's struggling Birmingham side five points above the drop zone.
Nottingham Forest grabbed a stoppage time equaliser against Derby County as the East Midlands derby ended 2-2 at the City Ground in Mark Warburton's first match in charge, with visiting manager Gary Rowett also making his debut in the dug out.
Derby led 2-1 with goals from Matej Vydra and David Nugent after falling behind, but Forest's Daniel Pinillos struck in the 94th minute to earn a point that keeps the former English and European champions just above the relegation zone.
"It would have been very upsetting not to take something from the game," former Rangers boss Warburton said.
"After a really pleasing first half, it was frustrating to find yourself 2-1 down. But they showed great character and that got the late reward. We deserved the point."
Forest are a point above the drop zone where Blackburn Rovers, another club to have won the English title, have 40 after being denied a victory at home to Preston North End when the visitors scored in stoppage time for a 2-2 draw.
