On vectors to phl airport. Controller told us to descend to 6000', after reaching 6000' to slow to 210 KTS. We were on heading about 110 degree, just before reaching 6000' controller told us to turn to heading 230 degree. When passing through 210 degree controller asked us where we were going? First officer told him that he had turned us to 230 degree. Controller then told us to turn back to 090 degree. After reaching 090 degree controller asked us our speed. First officer replied 220 slowing to 210 degree. We were company flight czc. The first officer and I discussed this. We were both sure he had told czc to turn to heading 230 degree which we did. Both of our heading bugs were set at 230 degree and we both distinctly remember the heading instruction. I believe the controller made an error either in sending us in the wrong direction, or (and it seems more likely) he got our flight # mixed up with another flight #, something which happens quite often. Also on the frequency were company wdc and company dwu and I believe another company flight. He was quite busy and sounded tired.

Title: HEADING CHANGE GIVEN TO WRONG FLT.
Narrative: ON VECTORS TO PHL ARPT. CTLR TOLD US TO DSND TO 6000', AFTER REACHING 6000' TO SLOW TO 210 KTS. WE WERE ON HDG ABOUT 110 DEG, JUST BEFORE REACHING 6000' CTLR TOLD US TO TURN TO HDG 230 DEG. WHEN PASSING THROUGH 210 DEG CTLR ASKED US WHERE WE WERE GOING? F/O TOLD HIM THAT HE HAD TURNED US TO 230 DEG. CTLR THEN TOLD US TO TURN BACK TO 090 DEG. AFTER REACHING 090 DEG CTLR ASKED US OUR SPEED. F/O REPLIED 220 SLOWING TO 210 DEG. WE WERE COMPANY FLT CZC. THE F/O AND I DISCUSSED THIS. WE WERE BOTH SURE HE HAD TOLD CZC TO TURN TO HDG 230 DEG WHICH WE DID. BOTH OF OUR HDG BUGS WERE SET AT 230 DEG AND WE BOTH DISTINCTLY REMEMBER THE HDG INSTRUCTION. I BELIEVE THE CTLR MADE AN ERROR EITHER IN SENDING US IN THE WRONG DIRECTION, OR (AND IT SEEMS MORE LIKELY) HE GOT OUR FLT # MIXED UP WITH ANOTHER FLT #, SOMETHING WHICH HAPPENS QUITE OFTEN. ALSO ON THE FREQ WERE COMPANY WDC AND COMPANY DWU AND I BELIEVE ANOTHER COMPANY FLT. HE WAS QUITE BUSY AND SOUNDED TIRED.
