Narrative:
We were in a slow climb to FL390 at about FL385 to FL388, we encountered moderate turbulence with some wing rocking, as can occur in wake turbulence. The winds at altitude were only 270/12. We asked if there was anyone ahead of us on J6. ATC said a B767 at 12 mi ahead. We asked to offset a mi or 2 and we were back in smooth air. At FL390 we were given on course. I have had numerous wake turbulence encounters this summer. Almost always I was on a jet airway with very little wind at altitude.
