Narrative:
En route tpa to dtw. Filed route was J85 amg odf J145 hvq J85 djb dtw. I have flown tpa-dtw about 6 times in the last month and the route was always amg J85 djb. Unfortunately I assumed it was the same route (J85) without the detour over to odf. So I flew J85 all the way up to irq from amg. I discovered the error when I started to check our fuel state over irq and realized we were supposed to be going to odf instead. About this time ZTL gave us a heading for hvq, 'rest of route unchanged.' there was no mention made of our off course deviation. The problem complacency (and laziness) on my part. I'm starting to get a little too comfortable with the DC9 and the rtes we fly and I just wasn't thinking about what I was doing. It's a shame it took something like this to tighten me up again.

Title: AN ACR DC9 FLC FLEW THE RTE THAT THEY WERE USED TO FLYING AND NOT THE RTE THEY WERE CLRED TO FLY. THE ARTCC RADAR CTLR GAVE THEM A VECTOR BACK ON COURSE WITHOUT COMMENT.
Narrative: ENRTE TPA TO DTW. FILED RTE WAS J85 AMG ODF J145 HVQ J85 DJB DTW. I HAVE FLOWN TPA-DTW ABOUT 6 TIMES IN THE LAST MONTH AND THE RTE WAS ALWAYS AMG J85 DJB. UNFORTUNATELY I ASSUMED IT WAS THE SAME RTE (J85) WITHOUT THE DETOUR OVER TO ODF. SO I FLEW J85 ALL THE WAY UP TO IRQ FROM AMG. I DISCOVERED THE ERROR WHEN I STARTED TO CHK OUR FUEL STATE OVER IRQ AND REALIZED WE WERE SUPPOSED TO BE GOING TO ODF INSTEAD. ABOUT THIS TIME ZTL GAVE US A HEADING FOR HVQ, 'REST OF RTE UNCHANGED.' THERE WAS NO MENTION MADE OF OUR OFF COURSE DEV. THE PROB COMPLACENCY (AND LAZINESS) ON MY PART. I'M STARTING TO GET A LITTLE TOO COMFORTABLE WITH THE DC9 AND THE RTES WE FLY AND I JUST WASN'T THINKING ABOUT WHAT I WAS DOING. IT'S A SHAME IT TOOK SOMETHING LIKE THIS TO TIGHTEN ME UP AGAIN.
