Narrative:

Full flight, we have to prepare our own weight and balance forms. Several non revenues were trying to get on flight. We received several adjusted passenger counts before departure and the paperwork had to be redone. I asked passenger agent if all non revenues were on board and had a seat. Agent said yes. There was already a pilot on IOE sitting on the cockpit jumpseat. During the flight, another commuting pilot spent most of the flight in the cockpit. This is normal on a full flight. Later, the first officer reported that the commuting pilot had actually sat on the luggage in the cockpit for takeoff and landing. The WX at our destination was near mins in fog and snow. I never turned around to check how many people were in the cockpit. I was amazed that none of the cockpit crew members brought this to my attention. Very poor cockpit resource management on the part of the other crew members. Maybe the checklists and aom's should be revised for all cockpit members to respond to the challenges 'oxygen and interphones' and 'shoulder harnesses' as a way of increasing the awareness of exactly how many people are in the cockpit.

Title: AN ACR LGT CARRIED 5 PERSONS IN A 4 PERSON COCKPIT.

Narrative: FULL FLT, WE HAVE TO PREPARE OUR OWN WT AND BAL FORMS. SEVERAL NON REVENUES WERE TRYING TO GET ON FLT. WE RECEIVED SEVERAL ADJUSTED PAX COUNTS BEFORE DEP AND THE PAPERWORK HAD TO BE REDONE. I ASKED PAX AGENT IF ALL NON REVENUES WERE ON BOARD AND HAD A SEAT. AGENT SAID YES. THERE WAS ALREADY A PLT ON IOE SITTING ON THE COCKPIT JUMPSEAT. DURING THE FLT, ANOTHER COMMUTING PLT SPENT MOST OF THE FLT IN THE COCKPIT. THIS IS NORMAL ON A FULL FLT. LATER, THE FO RPTED THAT THE COMMUTING PLT HAD ACTUALLY SAT ON THE LUGGAGE IN THE COCKPIT FOR TKOF AND LNDG. THE WX AT OUR DEST WAS NEAR MINS IN FOG AND SNOW. I NEVER TURNED AROUND TO CHK HOW MANY PEOPLE WERE IN THE COCKPIT. I WAS AMAZED THAT NONE OF THE COCKPIT CREW MEMBERS BROUGHT THIS TO MY ATTN. VERY POOR COCKPIT RESOURCE MGMNT ON THE PART OF THE OTHER CREW MEMBERS. MAYBE THE CHKLISTS AND AOM'S SHOULD BE REVISED FOR ALL COCKPIT MEMBERS TO RESPOND TO THE CHALLENGES 'OXYGEN AND INTERPHONES' AND 'SHOULDER HARNESSES' AS A WAY OF INCREASING THE AWARENESS OF EXACTLY HOW MANY PEOPLE ARE IN THE COCKPIT.
