How to Manage an Unmanageable Boss?

I will be working for a VP who is known for constantly changing travel arrangements, re-scheduling meetings several times and basically making everyone he interacts with schedule around his schedule. You know the type constantly has cell phone stuck to ear and schedules several things in one day (despite the fact you’ve told him). Any useful suggestion on how to manage this boss? Before you ask why.. it’s a big jump in pay for me.
