No GA at 38,000 feet, plenty of "GA" all around you on the roads with no ATC keeping you apart
Triple + the hours for the same pay
No work life balance
Sleep in the box
No roos at 38,000 feet
No FO to help out
Pre flight walk around gets you dirty
Blue singlet uniform
Pie and coke for lunch
No weighbridges at 38,000 feet, nor airway patrol
One benefit is that you can cop a gobby at most truck stops
