Does anyone know if LMU is NOT offered if you are wait listed for J? Both of my flights last two times I didnt see an LMU offer (CUN-YUL esp odd since it had 6 open J seats) - I was literally upgraded from Standard which tells you all there need to know about the situation.

Update: Lounge Agent was able to pull YUL-GRU LMU price for me: $2399 from PY Lowest. J1 (Option not available in "manage your check-in" or at the time of online check-in).
