ABOUT 5 MINS PRIOR TO DEP; RECEIVED CALL FROM THE CREW SAYING RWYS MIGHT BE 16/34. I LOOKED IN THE COMPUTER. SHOWED RWYS WERE 15/33. THEY WERE GOING TO VERIFY. I GOT OUT THE APCH PLATES AND SAW RWYS 16/34. WHILE I WAS VERIFYING INFO; THE FLT PUSHED OFF THE GATE. I SENT THE ACFT 3 ACARS MESSAGES STATING RWYS 16/34 WERE CORRECT AND GETTING CORRECT WTS. FLT TOOK OFF BEFORE THEY SAW THE ACARS MESSAGES. SUPPLEMENTAL INFO FROM ACN 443021: COCKPIT CREW PROVIDED WITH DEP WT MANIFEST AND COMPUTERIZED TKOF PERFORMANCE COMPUTATIONS FOR BOTH RWYS AT JACKSON. THE FO REMARKED THAT OUR TKOF DATA WAS FOR RWYS 15/33. CURRENT AIRFIELD DIAGRAM SHOWS RWYS 16/34. DISPATCH CTR WAS CONTACTED AND INFORMED. CREW WAS TOLD 'THAT'S ALL WE HAVE IN THE COMPUTER.'
