pree56,
I would like to address your assumption that there is less responsibility in freight flying. Please do not take this wrong I am just trying to correct an assumption that the public and some pilots have about freight airlines and pilots. I have been both a jet passenger airline pilot and a wide body freight pilot. The job and responsibilities are the same. While the pax pilot may have to deal with passenger and F/A issues he will probably never deal with large quantities of hazmat or loads like livestock. While the jobs differ the responsibility is the same. Once in the air the job is identical especially after 9/11 and the advent of armoured and locked cockpit doors. If the pax crew or the freight crew put a large jet into a neighborhood the result is the same.
As a side note the highest paid pilots by far in the United States nowadays fly for FedEx and UPS, both all freight airlines.
