Narrative:
This is to report a possible unstabilized approach into jac. I was the PF. After the IFR arrival into jac we reported the runway in sight and were cleared for a visual. I maneuvered east of the snake river as per company specific page; and was on the GS and configuring when we began to pick up a tailwind. At first it was insidious; gradually increasing the lower we descended; and it began to upset my plan for slowing and configuring. We were in a stabilized approach at 500 ft; in accordance with SOP; however on the fast side of the airspeed range at vls +15 KTS. I had expected the tailwind to decrease as we got closer to the runway; and had talked about this with the copilot; since the tower reported winds were a direct crosswind at 10 KTS. Unexpectedly; the tailwind did not diminish; and to remain on profile I unwillingly allowed the airspeed to increase above the limit for a stabilized approach. I touched down at the 2000 ft point; as required and the landing was uneventful. I realize how critical airspeed control is on approachs into jac; and have to admit I felt pressure to get the airplane on the ground during this approach. We were over an hour late departing ZZZ; jac operations had sent us a message stating that they were going to work as hard as the could to make our turn quick; and that we had many tight connections on the return flight. I also feel that industry events are distracting to all of us; and need to recommit myself to flying with safety as my utmost priority.

Title: AN ACR FLT CREW ENCOUNTERED A TAILWIND ON FINAL APP TO JAC AND ALLOWED AN UNSTABILIZED APP TO CONTINUE TO LANDING.
Narrative: THIS IS TO RPT A POSSIBLE UNSTABILIZED APCH INTO JAC. I WAS THE PF. AFTER THE IFR ARR INTO JAC WE RPTED THE RWY IN SIGHT AND WERE CLRED FOR A VISUAL. I MANEUVERED E OF THE SNAKE RIVER AS PER COMPANY SPECIFIC PAGE; AND WAS ON THE GS AND CONFIGURING WHEN WE BEGAN TO PICK UP A TAILWIND. AT FIRST IT WAS INSIDIOUS; GRADUALLY INCREASING THE LOWER WE DSNDED; AND IT BEGAN TO UPSET MY PLAN FOR SLOWING AND CONFIGURING. WE WERE IN A STABILIZED APCH AT 500 FT; IN ACCORDANCE WITH SOP; HOWEVER ON THE FAST SIDE OF THE AIRSPD RANGE AT VLS +15 KTS. I HAD EXPECTED THE TAILWIND TO DECREASE AS WE GOT CLOSER TO THE RWY; AND HAD TALKED ABOUT THIS WITH THE COPLT; SINCE THE TWR RPTED WINDS WERE A DIRECT XWIND AT 10 KTS. UNEXPECTEDLY; THE TAILWIND DID NOT DIMINISH; AND TO REMAIN ON PROFILE I UNWILLINGLY ALLOWED THE AIRSPD TO INCREASE ABOVE THE LIMIT FOR A STABILIZED APCH. I TOUCHED DOWN AT THE 2000 FT POINT; AS REQUIRED AND THE LNDG WAS UNEVENTFUL. I REALIZE HOW CRITICAL AIRSPD CTL IS ON APCHS INTO JAC; AND HAVE TO ADMIT I FELT PRESSURE TO GET THE AIRPLANE ON THE GND DURING THIS APCH. WE WERE OVER AN HR LATE DEPARTING ZZZ; JAC OPS HAD SENT US A MESSAGE STATING THAT THEY WERE GOING TO WORK AS HARD AS THE COULD TO MAKE OUR TURN QUICK; AND THAT WE HAD MANY TIGHT CONNECTIONS ON THE RETURN FLT. I ALSO FEEL THAT INDUSTRY EVENTS ARE DISTRACTING TO ALL OF US; AND NEED TO RECOMMIT MYSELF TO FLYING WITH SAFETY AS MY UTMOST PRIORITY.
