Narrative:
While en route, on our clearance we mistook the clearance 'barretts mtn, to linco intersection' and instead we started barretts mtn to lynno intersection. Both pilots were new to this routing and both misunderstood the intersection name - linco is 203 degree off bzm and lynno is 115 degree off bzm, both approximately 20-25 NM from bzm. There was no conflict and it is suggested that intxns which sound so similar not be used in such a close area to one another. Supplemental information from acn 108919: I was flying as a new captain with a new company with a new first officer (new to the company also) on a route that I was not familiar with in mod turbulence. My first officer was navigating for me and misread the intersection we were supposed to go to (linco). We started to go to lynno.

Title: SIMILAR SOUNDING INTXNS OFF BZM VOR. LINCO ON COMMERCIAL LOW ALT NAVIGATION CHART AND NOAA. LYNNO ON MAJIC ONE ARR STAR TO CHARLOTTE, NC.
Narrative: WHILE ENRTE, ON OUR CLRNC WE MISTOOK THE CLRNC 'BARRETTS MTN, TO LINCO INTXN' AND INSTEAD WE STARTED BARRETTS MTN TO LYNNO INTXN. BOTH PLTS WERE NEW TO THIS ROUTING AND BOTH MISUNDERSTOOD THE INTXN NAME - LINCO IS 203 DEG OFF BZM AND LYNNO IS 115 DEG OFF BZM, BOTH APPROX 20-25 NM FROM BZM. THERE WAS NO CONFLICT AND IT IS SUGGESTED THAT INTXNS WHICH SOUND SO SIMILAR NOT BE USED IN SUCH A CLOSE AREA TO ONE ANOTHER. SUPPLEMENTAL INFORMATION FROM ACN 108919: I WAS FLYING AS A NEW CAPT WITH A NEW COMPANY WITH A NEW F/O (NEW TO THE COMPANY ALSO) ON A ROUTE THAT I WAS NOT FAMILIAR WITH IN MOD TURBULENCE. MY F/O WAS NAVIGATING FOR ME AND MISREAD THE INTXN WE WERE SUPPOSED TO GO TO (LINCO). WE STARTED TO GO TO LYNNO.
