From my trip they were really close to the time they said, but that could change due to road conditions or wrecks traffic is a factor
my friend that I took to the bus station that rode a bus from Knoxville to Nashville he said they got in there pretty close to the time just give or take 15-30 minutes but it was pretty close
My trip from New York to Atlanta all stops were close on time
You have to consult with them....
