Narrative:

I flew ship #xxy from mco to lga. Our ACARS message for gate assignment indicated gate right even though our flight plan indicated gate Q. I parked the aircraft (ship #xxy at gate right. The passenger deplaned and I went to the gate to get our paperwork for our leg to pbi. (Unknown to me at the time, ship #xyx had originally been assigned gate right but had been parked at gate Q.) our preflight preparation was normal and we received the proper paperwork for our flight (fuel slip, flight plan, WX and dispatch release.) what was not correct was the ship # on the dispatch release -- it showed ship # xyx instead of ship # xxy. We got a message on our ACARS en route to pbi to check our ship data (and I have since learned that ship # xyx received the same message en route to msy.) apparently we should have flown ship # xyx to pbi and they should have flown ship # xxy to msy. The flight # was current on our final weight and data report but the wrong ship # means that our operating empty weight was off by a couple of hundred pounds. The entire incident could have been prevented had I, the captain, paid more attention to the ship # on our paperwork, instead of just the flight number. Supplemental information from acn 289057: when all the paperwork for flight was received in lga, the flight plan fuel load was verified against what was actually on board the aircraft, and the route was verified against the printed pre departure clearance and the route received from clearance delivery. The awabs was checked for proper fuel and passenger count. I absolutely remember checking the flight number and date on all paperwork.

Title: 2 TRIPS FLOWN IN THE WRONG ACFT. BOTH CREWS MADE THE SAME MISTAKE AS DID THE AGENTS, BAGGAGE HANDLERS AND FUELERS.

Narrative: I FLEW SHIP #XXY FROM MCO TO LGA. OUR ACARS MESSAGE FOR GATE ASSIGNMENT INDICATED GATE R EVEN THOUGH OUR FLT PLAN INDICATED GATE Q. I PARKED THE ACFT (SHIP #XXY AT GATE R. THE PAX DEPLANED AND I WENT TO THE GATE TO GET OUR PAPERWORK FOR OUR LEG TO PBI. (UNKNOWN TO ME AT THE TIME, SHIP #XYX HAD ORIGINALLY BEEN ASSIGNED GATE R BUT HAD BEEN PARKED AT GATE Q.) OUR PREFLT PREPARATION WAS NORMAL AND WE RECEIVED THE PROPER PAPERWORK FOR OUR FLT (FUEL SLIP, FLT PLAN, WX AND DISPATCH RELEASE.) WHAT WAS NOT CORRECT WAS THE SHIP # ON THE DISPATCH RELEASE -- IT SHOWED SHIP # XYX INSTEAD OF SHIP # XXY. WE GOT A MESSAGE ON OUR ACARS ENRTE TO PBI TO CHK OUR SHIP DATA (AND I HAVE SINCE LEARNED THAT SHIP # XYX RECEIVED THE SAME MESSAGE ENRTE TO MSY.) APPARENTLY WE SHOULD HAVE FLOWN SHIP # XYX TO PBI AND THEY SHOULD HAVE FLOWN SHIP # XXY TO MSY. THE FLT # WAS CURRENT ON OUR FINAL WT AND DATA RPT BUT THE WRONG SHIP # MEANS THAT OUR OPERATING EMPTY WT WAS OFF BY A COUPLE OF HUNDRED LBS. THE ENTIRE INCIDENT COULD HAVE BEEN PREVENTED HAD I, THE CAPT, PAID MORE ATTN TO THE SHIP # ON OUR PAPERWORK, INSTEAD OF JUST THE FLT NUMBER. SUPPLEMENTAL INFO FROM ACN 289057: WHEN ALL THE PAPERWORK FOR FLT WAS RECEIVED IN LGA, THE FLT PLAN FUEL LOAD WAS VERIFIED AGAINST WHAT WAS ACTUALLY ON BOARD THE ACFT, AND THE RTE WAS VERIFIED AGAINST THE PRINTED PDC AND THE RTE RECEIVED FROM CLRNC DELIVERY. THE AWABS WAS CHKED FOR PROPER FUEL AND PAX COUNT. I ABSOLUTELY REMEMBER CHKING THE FLT NUMBER AND DATE ON ALL PAPERWORK.
