Narrative:
Approximately XA00, called crp clearance delivery for IFR crp-dwh. Given: 'dwh via gland 7 - corpus transition M11000, frequency and squawk.' for yrs this has been, M12000 expect xxxxxx 10 mins. Should have asked. Read back '11000 ft.' 'readback correct.' frequency change from local to departure. Initial contact 'naaaa out of 2300 ft for 11000 ft.' response, 'naaaaa heading such and such to intercept then own navigation.' passing 10600 ft, departure calls 'verify level 10000 ft.' my reply, 'negative, through 10700 ft for 11000 ft. We were given clearance straight to 11000 ft.' silence for 30 seconds and the frequency change to center. Center did not sound happy I am in their airspace prior to call. Several chances to prevent this including departure control (myself?) and clearance delivery. We get used to what should be heard and sometimes ignore the errors.

Title: A COMMERCIAL INST RATED PLT DEPARTING CRP FOR DWH REQUESTS AND RECEIVES IFR CLRNC FROM CRP CLRNC DELIVERY THAT CONTAINS A DIFFERENT ALT THAN HE IS ACCUSTOMED TO RECEIVING. AFTER DEPARTING AND CONTACTING DRP DEP AND ZHU THERE IS CONFUSION AS TO HIS CLRED ALT.
Narrative: APPROX XA00, CALLED CRP CLRNC DELIVERY FOR IFR CRP-DWH. GIVEN: 'DWH VIA GLAND 7 - CORPUS TRANSITION M11000, FREQ AND SQUAWK.' FOR YRS THIS HAS BEEN, M12000 EXPECT XXXXXX 10 MINS. SHOULD HAVE ASKED. READ BACK '11000 FT.' 'READBACK CORRECT.' FREQ CHANGE FROM LCL TO DEP. INITIAL CONTACT 'NAAAA OUT OF 2300 FT FOR 11000 FT.' RESPONSE, 'NAAAAA HDG SUCH AND SUCH TO INTERCEPT THEN OWN NAV.' PASSING 10600 FT, DEP CALLS 'VERIFY LEVEL 10000 FT.' MY REPLY, 'NEGATIVE, THROUGH 10700 FT FOR 11000 FT. WE WERE GIVEN CLRNC STRAIGHT TO 11000 FT.' SILENCE FOR 30 SECONDS AND THE FREQ CHANGE TO CTR. CTR DID NOT SOUND HAPPY I AM IN THEIR AIRSPACE PRIOR TO CALL. SEVERAL CHANCES TO PREVENT THIS INCLUDING DEP CTL (MYSELF?) AND CLRNC DELIVERY. WE GET USED TO WHAT SHOULD BE HEARD AND SOMETIMES IGNORE THE ERRORS.
