Narrative:

Air carrier X was sbound at FL240 J209 sby. Foreign air carrier Y departed iad eastbound at FL230 requesting FL330. Air carrier Y kept requesting higher. I thought air carrier X was on J37, an airway that would take the aircraft behind air carrier Y, so I climbed air carrier Y to FL290. Right at that time I realized that air carrier X was not on an airway to pass behind air carrier Y. I then asked air carrier Y to expedite the climb. When I saw he still wasn't going to climb fast enough I turned both aircraft 40 degree, but still lost separation.

Original NASA ASRS Text

Title: LESS THAN STANDARD SEPARATION BETWEEN ACR AND FOREIGN ACR. OPERATIONAL ERROR.

Narrative: ACR X WAS SBOUND AT FL240 J209 SBY. FOREIGN ACR Y DEPARTED IAD EBOUND AT FL230 REQUESTING FL330. ACR Y KEPT REQUESTING HIGHER. I THOUGHT ACR X WAS ON J37, AN AIRWAY THAT WOULD TAKE THE ACFT BEHIND ACR Y, SO I CLIMBED ACR Y TO FL290. RIGHT AT THAT TIME I REALIZED THAT ACR X WAS NOT ON AN AIRWAY TO PASS BEHIND ACR Y. I THEN ASKED ACR Y TO EXPEDITE THE CLIMB. WHEN I SAW HE STILL WASN'T GOING TO CLIMB FAST ENOUGH I TURNED BOTH ACFT 40 DEG, BUT STILL LOST SEPARATION.
