A B767-300 RPTS INADEQUATE REST ON LONG OVERWATER FLTS DUE TO CREW REST SEAT LOCATED NEXT TO OCCUPIED PAX SEAT.

Narrative

TONIGHT WAS THE SECOND TIME; ON A LONG ALL-NIGHT FLT FROM ZZZ TO NEW YORK; WHERE THERE WAS A REVENUE PAX IN THE SEAT NEXT TO THE CREW REST SEAT. IN ONE CASE; IT WAS A LARGE MAN THAT KEPT MOVING AND HIS ARMS AND SHOULDERS WERE OVER MY SEAT; MOVING ALL THE TIME WITH LOUD SNORING. LAST NIGHT; IT WAS A REGULAR SIZE MAN; BUT HE KEPT MAKING ABRUPT MOVEMENTS EVERY 10 SECONDS AND SINCE THE 2 SEATS ARE CONNECTED; IT WAS IMPOSSIBLE TO SLEEP IN MY SEAT. WHEN I RETURNED TO THE COCKPIT; AFTER NOT GETTING ONE MIN OF SLEEP; I WAS NOT A SAFE PLT. MY REACTIONS WERE SLOW; MY THINKING WAS SLOW AND I WAS IRRITATED. I DID NOT PERFORM AS I WOULD EXPECT MYSELF OR ANY OTHER PROFESSIONAL PLT TO PERFORM. REVENUE SHOULD NOT BE MORE IMPORTANT THAN SAFETY AND THIS IS A SEVERE SAFETY ISSUE THAT CAN EASILY BE CORRECTED. SUPPLEMENTAL INFO FROM ACN 598692: PROX OF SEAT PREVENTS PROPER CREW REST WHEN SEAT IS OCCUPIED DUE TO NORMAL PAX MOVEMENT; USE OF DVD'S BY PAX; MEAL SVCS; FOOTREST EXTENSIONS AND RETRACTIONS; ETC. SEAT ALSO BLOCKED FROM NORMAL EGRESS WHEN SEAT FOOTREST IS EXTENDED HINDERING TIMELY ACCESS TO COCKPIT IN CASE OF ABNORMAL SITS INCLUDING ACFT EMERS AND VARIOUS THREAT LEVELS TO COCKPIT.
