Narrative:
Takeoff altimeter setting 30.32. Pilots did not reset to 29.92 climbing through FL180. Leveled off at FL310 on altimeter. After resetting, actual altitude was FL306, climbed to FL310. No conflicts noted. Corrective action is to complete the climb check, including resetting altimeter to FL180 29.92. Supplemental information from acn 396490: distraction by flight attendant and radio call passing FL180 and thus missed resetting altimeter at 29.92. Shortly after leveloff, center controller asked us to check our altimeter as we were a little off altitude.

Title: A B757 FLC CLBING TO FL310 FAILS TO RESET ALTIMETER TO STANDARD SETTING CLBING THROUGH FL180 AND LEVELS OFF BELOW ASSIGNED ALT IN ZMP AIRSPACE.
Narrative: TKOF ALTIMETER SETTING 30.32. PLTS DID NOT RESET TO 29.92 CLBING THROUGH FL180. LEVELED OFF AT FL310 ON ALTIMETER. AFTER RESETTING, ACTUAL ALT WAS FL306, CLBED TO FL310. NO CONFLICTS NOTED. CORRECTIVE ACTION IS TO COMPLETE THE CLB CHK, INCLUDING RESETTING ALTIMETER TO FL180 29.92. SUPPLEMENTAL INFO FROM ACN 396490: DISTR BY FLT ATTENDANT AND RADIO CALL PASSING FL180 AND THUS MISSED RESETTING ALTIMETER AT 29.92. SHORTLY AFTER LEVELOFF, CTR CTLR ASKED US TO CHK OUR ALTIMETER AS WE WERE A LITTLE OFF ALT.
