Narrative:
Location: bonham arrival/lemyn intersection. Did not reset altimeters out of 18000 ft. Was to cross lemyn intersection at 11000 ft. With incorrect altimeter setting was 400 ft high. Noticed mistake and reset altimeters. No comment made from ATC. Supplemental information from acn 395886: on the flight from phl to dfw we were given the bonham two BYP2 arrival for dfw. Approaching byp VOR we were given a descent to FL190 then to FL180 then 15000 ft and then told to cross lemyn at 11000 ft and to delete all speeds on the STAR. Because of the stepdowns we delayed resetting altimeters. Lemyn is 29 DME. At 30 DME we realized that we did not reset from 29.92 to 30.30 which caused us to level off approximately 400 ft high. We reset and descended to 11000 ft by 32 DME.

Title: S80 FLC FAILS TO RESET THEIR ALTIMETERS TO LCL QNH FOR AN ALT XING ON A STAR ARR PROC. RPTRS CITE NUMEROUS ALT CHANGES IN DSCNT PROC.
Narrative: LOCATION: BONHAM ARR/LEMYN INTXN. DID NOT RESET ALTIMETERS OUT OF 18000 FT. WAS TO CROSS LEMYN INTXN AT 11000 FT. WITH INCORRECT ALTIMETER SETTING WAS 400 FT HIGH. NOTICED MISTAKE AND RESET ALTIMETERS. NO COMMENT MADE FROM ATC. SUPPLEMENTAL INFO FROM ACN 395886: ON THE FLT FROM PHL TO DFW WE WERE GIVEN THE BONHAM TWO BYP2 ARR FOR DFW. APCHING BYP VOR WE WERE GIVEN A DSCNT TO FL190 THEN TO FL180 THEN 15000 FT AND THEN TOLD TO CROSS LEMYN AT 11000 FT AND TO DELETE ALL SPDS ON THE STAR. BECAUSE OF THE STEPDOWNS WE DELAYED RESETTING ALTIMETERS. LEMYN IS 29 DME. AT 30 DME WE REALIZED THAT WE DID NOT RESET FROM 29.92 TO 30.30 WHICH CAUSED US TO LEVEL OFF APPROX 400 FT HIGH. WE RESET AND DSNDED TO 11000 FT BY 32 DME.
