Are you sure it is that layout for the fin of the plane that is flying your route?
Most of the time (albeit almost all on YOW-FRA / YOW-LHR / YYZ-TLV, etc.) I get one of the other two layouts which have the slightly larger forward Y cabin where 14 is not against the lav or gallery.
If I fail on Aerolotto I usually check at the gate to see if someone who won moved out of row 12 and I get moved up there. Works sometimes
