If there is no change of concourse, it’s perfectly fine. Basically if your ticket is with the same airline it should not be a problem. The concourses are very linear and easy to navigate, with large waiting halls where passengers embark and disembark. If you need to go between concourses then budget 10-15mins walking at a brisk pace
Some plane stops or departs from a remote stand, and this can be a source of delays when deplaning and emplaning to wait for buses etc. The stands aren’t that remote, maybe 100yards from the terminal building, so once you’re in a bus it’s pretty quick, but it’s a bigger hassle to snake your way back to the concourses. If you miss the early buses, it can take up to 20mins from the opening of the airplane doors to reaching the terminal.
