I jumpseat all the time. My company allows its employees to utilize company aircraft for personal travel, which is free. Other carriers may allow only business travel on their aircraft. I heard some time ago that UPS was going to convert some of their planes to passenger mode on weekends or something but I don't know if that ever got "off the ground". As for riding in the cockpit: yes, our company allows jumpseaters in the cockpit, but I have never been offered cigs or porn by the pilots! I have been privileged to ride in the A300, DC-10 and 727 cockpits. As for your question about pricing, I don't think any carrier would allow a non-employee to ride in its aircraft (for legal reasons), unless UPS is still doing the cargo/passenger switch thing. If you need any more info, let me know.
