Even if she would be flying her own plane (and she wouldn't be the only pop/rock star who does, like for example Bruce Dickinson of Iron Maiden) the second pilot would prepare everything to be ready for the anticipated departure time. All she would have to do then is close the door, get into her seat and release the parking brake.
