Narrative:
Climbing out of FL345 for FL350, cabin popped and began climbing at 2000 FPM. Immediately crew put oxygen masks on, checked the outflow valves, closed and asked for lower. Aircraft leveled out until clearance to 14000 ft was received. This came almost immediately. An emergency was never declared and priority was not given. Didn't declare emergency because ATC allowed for immediate descent and it was not an explosive decompression, ie, cabin only climbed between 2000-3000 FPM. We continued descent down to 10000 ft and returned to departure airport (fxe).

ACFT LEVELED OUT UNTIL CLRNC TO 14000 FT WAS RECEIVED. THIS CAME ALMOST IMMEDIATELY. AN EMER WAS NEVER DECLARED AND PRIORITY WAS NOT GIVEN. DIDN'T DECLARE EMER BECAUSE ATC ALLOWED FOR IMMEDIATE DSCNT AND IT WAS NOT AN EXPLOSIVE DECOMPRESSION, IE, CABIN ONLY CLBED BTWN 2000-3000 FPM. WE CONTINUED DSCNT DOWN TO 10000 FT AND RETURNED TO DEP ARPT (FXE).
