Narrative:

We were on the polar arrival into dtw. Before the descent checklist, we briefed for the ILS runway 22R. This was the most logical for an arrival from the west. At approximately 20 mi west of flint VOR, cle center gave us a short cut vector to intercept the dtw 343 degree radial and later was told to expect runway 21L. We re-briefed for the runway 21L approach. When handed over to dtw approach, we were given a couple of vectors along with one to intercept 'the localizer.' we were aligned on the centerline of runway 21L when approach gave us a vector to 're-intercept.' I informed him we were right on the centerline. He said runway 22R not runway 21L. We intercepted runway 22R without incident. I told approach that we were told to expect runway 21L and had no further instructions to the contrary. Dtw approach should have given us the runway number with the 'intercept the localizer' clearance.

Title: DC9 FLC PLAN FOR ZOB ASSIGNED DTW RWY 21L APCH, ONLY TO BE ADVISED WHEN TOLD AFTER COM TRANSFER TO INTERCEPT THE FINAL BY D21 THAT HE MEANT THE RWY 22L FINAL APCH COURSE.

Narrative: WE WERE ON THE POLAR ARRIVAL INTO DTW. BEFORE THE DSCNT CHECKLIST, WE BRIEFED FOR THE ILS RWY 22R. THIS WAS THE MOST LOGICAL FOR AN ARRIVAL FROM THE WEST. AT APPROX 20 MI WEST OF FLINT VOR, CLE CENTER GAVE US A SHORT CUT VECTOR TO INTERCEPT THE DTW 343 DEG RADIAL AND LATER WAS TOLD TO EXPECT RWY 21L. WE RE-BRIEFED FOR THE RWY 21L APCH. WHEN HANDED OVER TO DTW APCH, WE WERE GIVEN A COUPLE OF VECTORS ALONG WITH ONE TO INTERCEPT 'THE LOC.' WE WERE ALIGNED ON THE CENTERLINE OF RWY 21L WHEN APCH GAVE US A VECTOR TO 'RE-INTERCEPT.' I INFORMED HIM WE WERE RIGHT ON THE CENTERLINE. HE SAID RWY 22R NOT RWY 21L. WE INTERCEPTED RWY 22R WITHOUT INCIDENT. I TOLD APCH THAT WE WERE TOLD TO EXPECT RWY 21L AND HAD NO FURTHER INSTRUCTIONS TO THE CONTRARY. DTW APCH SHOULD HAVE GIVEN US THE RWY NUMBER WITH THE 'INTERCEPT THE LOC' CLRNC.
