Noticed something similar the other day for a one way in Sept.
YVR/FRA/ATH - AC J, LH Y - 124.6k
YVR/FRA/ATH - AC Y, A3 J - 85k
YVR/FRA/SKG - AC J, LH Y - 126.3k
YVR/FRA/SKG - AC Y, A3 J - 70k
YVR/FRA/RHO - AC J, A3 Y - 122.7k
YVR/FRA/IST - AC leg Y, 2nd leg TK J - 85k
YVR/FRA/IST - AC leg J, 2nd leg LH Y - 94.3k (!)
YVR/FRA - in J - 156.4k
