Narrative:
Departed for bmi, cleared to 14000 ft with atl departure, then handed off to ZTL at around 12000-13000 ft. We were also on a heading assigned by departure. ZTL then gave us 15000 ft. Then they came back with a new heading and direct to the next fix. I turned to that heading and was still in a climb to 15000 ft. I thought he also gave us a new altitude of FL230. As we passed through 15300 ft, the altitude alerter went off and I leveled off and questioned the altitude with the first officer. He confirmed 15000 ft. I immediately returned to 15000 ft. Upon reaching 15000 ft, we were questioned about our altitude by ATC and we informed him 15000 ft which is what we were at. Maximum deviation from the altitude of 15000 ft was 15400 ft, for just a few seconds. 99.9% of the time atl departure gives us 14000 ft and a handoff. ZTL then gives us on course and FL230. But not this day. I think you get used to getting the same clearance every day and you tend not to be as focused as you would in a new environment. Complacent.

Title: DC9 FLT CREW ON DEP ATL, ATTEMPT TO ANTICIPATE ZTL CLB CLRNC WHICH DOES NOT MATERIALIZE, RESULTING IN AN ALT OVERSHOOT.
Narrative: DEPARTED FOR BMI, CLRED TO 14000 FT WITH ATL DEP, THEN HANDED OFF TO ZTL AT AROUND 12000-13000 FT. WE WERE ALSO ON A HDG ASSIGNED BY DEP. ZTL THEN GAVE US 15000 FT. THEN THEY CAME BACK WITH A NEW HDG AND DIRECT TO THE NEXT FIX. I TURNED TO THAT HDG AND WAS STILL IN A CLB TO 15000 FT. I THOUGHT HE ALSO GAVE US A NEW ALT OF FL230. AS WE PASSED THROUGH 15300 FT, THE ALT ALERTER WENT OFF AND I LEVELED OFF AND QUESTIONED THE ALT WITH THE FO. HE CONFIRMED 15000 FT. I IMMEDIATELY RETURNED TO 15000 FT. UPON REACHING 15000 FT, WE WERE QUESTIONED ABOUT OUR ALT BY ATC AND WE INFORMED HIM 15000 FT WHICH IS WHAT WE WERE AT. MAX DEV FROM THE ALT OF 15000 FT WAS 15400 FT, FOR JUST A FEW SECONDS. 99.9% OF THE TIME ATL DEP GIVES US 14000 FT AND A HDOF. ZTL THEN GIVES US ON COURSE AND FL230. BUT NOT THIS DAY. I THINK YOU GET USED TO GETTING THE SAME CLRNC EVERY DAY AND YOU TEND NOT TO BE AS FOCUSED AS YOU WOULD IN A NEW ENVIRONMENT. COMPLACENT.
