Narrative:
The aircraft came inbound as flight XX1. The first officer left XX1 in the ACARS and also saw the inbound number XX1 posted outside the jetway. He thought our flight was XX1. I had written YY1 on the release and also on paper on my side. We taxied out and due to fairly similar call sign, I did not notice the first officer say XX1 as opposed to YY1. We were cleared into position, again I did not catch the different call sign. With the first officer flying, the tower cleared XX1 for takeoff. I said negative we are YY1. There were a few seconds of confusion, but we (XX1) were cleared for takeoff to our destination. There were no traffic conflicts or safety concerns, just confusion over call signs. I think the problem lies in the fact that some days we fly as many as 6 legs -- all with different call signs.
Original NASA ASRS Text
Title: ACR USED PREVIOUS FLT'S CALL SIGN THROUGHOUT TAXI UNTIL IT WAS DISCOVERED AT CLRNC FOR TKOF.
Narrative: THE ACFT CAME INBOUND AS FLT XX1. THE FO LEFT XX1 IN THE ACARS AND ALSO SAW THE INBOUND NUMBER XX1 POSTED OUTSIDE THE JETWAY. HE THOUGHT OUR FLT WAS XX1. I HAD WRITTEN YY1 ON THE RELEASE AND ALSO ON PAPER ON MY SIDE. WE TAXIED OUT AND DUE TO FAIRLY SIMILAR CALL SIGN, I DID NOT NOTICE THE FO SAY XX1 AS OPPOSED TO YY1. WE WERE CLRED INTO POS, AGAIN I DID NOT CATCH THE DIFFERENT CALL SIGN. WITH THE FO FLYING, THE TWR CLRED XX1 FOR TKOF. I SAID NEGATIVE WE ARE YY1. THERE WERE A FEW SECONDS OF CONFUSION, BUT WE (XX1) WERE CLRED FOR TKOF TO OUR DEST. THERE WERE NO TFC CONFLICTS OR SAFETY CONCERNS, JUST CONFUSION OVER CALL SIGNS. I THINK THE PROB LIES IN THE FACT THAT SOME DAYS WE FLY AS MANY AS 6 LEGS -- ALL WITH DIFFERENT CALL SIGNS.
