Tango fare release patterns on Rouge
I have a question, does AC Rouge release cheaper tango fares (A, K, L, T)closer to the flight day, I am tracking a fare to LAS two weeks out, the flight seat map seems quite empty and I watched the S fares going from 9+ to 0 in a few hours on EF, so I am pretty sure these weren't purschased but they are just pulling the fare classes based on some kind of revenue model, what do you think?
