Depending on wind and humidity, a normal contrail can persist for 15-20 minutes, easy. Other days you can watch them disappear in seconds. Other days the plane doesn't leave a visible contrail.
Where I live, they can last the whole day, slowly spreading in width. More the norm than not. The last few days have been especially noteworthy.
