Inflight Event / Encounter Wake Vortex Encounter
General None Reported / Taken
Environment - Non Weather Related; Procedure
On arrival into Seattle ATC advised we were following a heavy 767. They made approach and landing on [Runway] 34R; and we landed 34L. On arrival just past FOOTT intersection I shallowed our descent rate; and re-VTO'ed (vertical guidance to waypoint) with a 3.4 degree glide path to remain above the heavy. Cleared for the visual I disengaged autopilot; and intercepted slightly wide and high on glide path. Wind was out of the east at about 15 kts; which I knew could push their wake into us. At about 4;000-5;000 ft we got substantial roll to the right; and slight pitching. We countered the roll and continued. The FA's (flight attendants) were seated and we heard no passenger complaints; though one of the forward passengers asked what that was; which I told him was wake turbulence. Even with my precautions of trying to stay above and wide; slowing a little more for better separation; and asking for more spacing from ATC; who was trying to keep us fast.
Medium Large Transport Captain reported encountering wake turbulence on arrival to SEA in trail of a B767.
