This is interesting to me for booking some CX awards from AS in the future. I searched a couple days around Xmas on EF: there are several Z1 seats on several LAX-HKG flights, but nothing shows up on QF or BA. I even tried a few married segments to see if it might pop up, but couldn't make any F seats appear. I don't have a CX acct, so if someone could also check that side it might help our DPs.
