Narrative:

I was 1 hour late due to maintenance problems at a stop en route. My arrival time was 3 min prior to scheduled jet departure (air carrier a run). The jet was waiting for me. I was told to expect a marshaller to guide me to the cargo door for the jet. Upon reaching the cargo area, a marshaller appeared where I expected he would be and seemed to be marshalling me towards the jet. In reality, his back was to me and he was marshalling an air carrier B jet. I did not see ????, the ramp was poorly lighted, and I was expecting him. The air carrier a marshaller was actually around the corner, behind their jet. I proceeded toward the air carrier B marshaller as he backed away believing he was leading me around the jet. When he realized I was following he signaled to stop. By the time I'd stopped I was in a position to see the air carrier a marshaller. At this time, the air carrier B marshaller, some what freaked out, departed. Air carrier B upset, airport authorities notified. Simple mistake.

Narrative: I WAS 1 HR LATE DUE TO MAINT PROBLEMS AT A STOP ENRTE. MY ARR TIME WAS 3 MIN PRIOR TO SCHEDULED JET DEPARTURE (ACR A RUN). THE JET WAS WAITING FOR ME. I WAS TOLD TO EXPECT A MARSHALLER TO GUIDE ME TO THE CARGO DOOR FOR THE JET. UPON REACHING THE CARGO AREA, A MARSHALLER APPEARED WHERE I EXPECTED HE WOULD BE AND SEEMED TO BE MARSHALLING ME TOWARDS THE JET. IN REALITY, HIS BACK WAS TO ME AND HE WAS MARSHALLING AN ACR B JET. I DID NOT SEE ????, THE RAMP WAS POORLY LIGHTED, AND I WAS EXPECTING HIM. THE ACR A MARSHALLER WAS ACTUALLY AROUND THE CORNER, BEHIND THEIR JET. I PROCEEDED TOWARD THE ACR B MARSHALLER AS HE BACKED AWAY BELIEVING HE WAS LEADING ME AROUND THE JET. WHEN HE REALIZED I WAS FOLLOWING HE SIGNALED TO STOP. BY THE TIME I'D STOPPED I WAS IN A POS TO SEE THE ACR A MARSHALLER. AT THIS TIME, THE ACR B MARSHALLER, SOME WHAT FREAKED OUT, DEPARTED. ACR B UPSET, ARPT AUTHORITIES NOTIFIED. SIMPLE MISTAKE.
