What is the worst aspect of business travel?
As an old road warrior, I've encountered terrible airports, dangerous shuttle drivers, disappearing flights, sauna-like conference rooms, and bizarre passengers.
Those irritations, however, are not common. I would submit that the most frequent downside of business travel is the hotel bed.
Peter Drucker once commented that he refused consulting projects that required him to spend a night away from home because he found it more and more difficult to sleep in a strange bed. George W. Bush used to take his own pillow with him on the campaign trail.
Those practices once sounded weird to me. They don't anymore.
