Hey is it possible to check where you are on the waitlist prior to 24hrs before dept? Do you need to be SE and get the info via a Concierge? They zeroed out the R space at t-7.5 for my upcoming flights and I am only E

Also I note that the flight to Eze is zeroed out but the same flight that routes via SCL has r space. Why would they offer R Space to SCL and not Eze? Is there anyway I can book to EZE but confirm the YYZ-SCL segment?
