Thank you for such useful information! I just created an account on Expert Flyer, but I'm not seeing a bunch of codes. I just did a search via "create a seat alert" and got the status on the round-trip flights. They're practically empty, especially in the economy seats. (They're AC 1946 on June 10/2018 and AC 1947 on June 25/2018). But I can't figure out where to see the sale at each fare code. Can someone help me figure this out?
