EA30. BOG DEP CTLR DID NOT KNOW THE CLRNC THE ACFT WAS FLYING.

Narrative

FLT XXX RECEIVED CLRNC TO MIA VIA THE BOSA 2 DEP ABL TRANSITION UG447. THIS IS THE WAY WE WERE FILED BY DISPATCH. SHORTLY AFTER TKOF WE WERE SWITCHED TO DEP CTL WHO IMMEDIATELY GAVE US A R TURN TO 020 DEGS AND A NEW AND DIFFERENT CLRNC WHICH NEITHER PLT UNDERSTOOD CLRLY; BUT WHICH WAS TOTALLY DIFFERENT FROM THE BOSA 2 DEP. AS WE WERE STILL RELATIVELY LOW AND IN THE MOUNTAINS; I INFORMED DEP CTL THAT WE WERE CLRED THE BOSA 2 DEP UG447. WE THEN UNDERSTOOD THE CTLR TO SAY THAT WE WERE CLRED THE GUAYMARAL 3 DEP; OVER ZIPNB AND THEN A301. THIS IS THE ROUTING WE USE 90% OF THE TIME AND I BELIEVE THE CTLR JUST NATURALLY EXPECTED US TO BE FLYING THAT ROUTING. SINCE WE HAD BEEN ORIGINALLY CLRED THE BOSA 2 DEP; HAD BRIEFED AND WERE WELL INTO THE DEP WITH NO APPARENT TFC CONFLICT; WE STAYED ON COURSE WHILE TRYING TO EXPLAIN TO DEP CTL THAT THAT WAS THE DEP ROUTING FOR WHICH WE HAD BEEN CLRED. AFTER A BRIEF SILENCE WE WERE SWITCHED TO CTR AND CLRED VIA FLT PLAN RTE. LATER IN PANAMA AIRSPACE WE CONFIRMED WITH THEM THAT THEY DID INDEED HAVE OUR FLT PLAN VIA UG447. BOGOTA OPS WAS CALLED PRIOR TO LEAVING THEIR RANGE AND THEY WERE APPRISED OF THE CONFUSION AND ASSURED ME THEY WOULD FOLLOW UP.
