Narrative:

An altrv (altitude reservation) was scheduled through ZTL involved 16 ftg's and 3 mlt's. Coordination about the altrv between the military, ZME and ZTL broke down as to what aircraft and at what time all aircraft would be transitioning ZTL. The altrv arrived with 6 fgt's and 1 mlt flight call sign was white a. We were advised the rest of the flight would be arriving at a later time with the call sign white B. Approximately 20 mins after white a passed through we received a handoff on mlt X, an mlt, at FL290. The flight progress strip said FL290. The computer indicated FL290. When mlt X checked on frequency he checked on, 'ZTL, this is mlt X at FL290.' there was no indication that mlt X was part of the altrv involving white a approximately 100 mi in front of him or white B 150 mi behind him. Subsequently a departure off atl, climbing westbound, and now leveled at FL280. Traffic was issued to the atl departure, air carrier Y. Traffic was issued to mlt X, '12 O'clock and 3 mi, westbound at FL280.' at this time mlt X informed me that he was an altrv of FL280-FL290. Mlt X was instructed to 'maintain FL290.' all the way through the sector mlt X never varied from FL290, but apparently he thought that he had authorization for FL270-FL290. Authorization we did ot know that he had. It turned out that originally mlt X wa part of the altrv issued to white a. Callback conversation with reporter revealed the following: reporter experience: 8 yrs radar, 1 yr non radar. Place of occurrence: vuz 020/45. Reporter stated that ZME had broken up the white a flight and failed to coordinate that mlt X was part of the altrv for white a. Reporter stated he had standard sep at all times. He notified the supervisor and the supervisor said, 'if the snitch didn't go off, forget it.' reporter followed up with ZME for his own knowledge.

COORD ABOUT THE ALTRV BTWN THE MIL, ZME AND ZTL BROKE DOWN AS TO WHAT ACFT AND AT WHAT TIME ALL ACFT WOULD BE TRANSITIONING ZTL. THE ALTRV ARRIVED WITH 6 FGT'S AND 1 MLT FLT CALL SIGN WAS WHITE A. WE WERE ADVISED THE REST OF THE FLT WOULD BE ARRIVING AT A LATER TIME WITH THE CALL SIGN WHITE B. APPROX 20 MINS AFTER WHITE A PASSED THROUGH WE RECEIVED A HDOF ON MLT X, AN MLT, AT FL290. THE FLT PROGRESS STRIP SAID FL290. THE COMPUTER INDICATED FL290. WHEN MLT X CHKED ON FREQ HE CHKED ON, 'ZTL, THIS IS MLT X AT FL290.'

SUBSEQUENTLY A DEP OFF ATL, CLBING WBND, AND NOW LEVELED AT FL280. TFC WAS ISSUED TO THE ATL DEP, ACR Y. TFC WAS ISSUED TO MLT X, '12 O'CLOCK AND 3 MI, WBND AT FL280.' AT THIS TIME MLT X INFORMED ME THAT HE WAS AN ALTRV OF FL280-FL290. MLT X WAS INSTRUCTED TO 'MAINTAIN FL290.'
