So apparently not all fare classes (ie, T class all the way for example) are eligible.
but this was like 9 months ago so things may have changed. I've not tried something similar since.
Are you saying that you sorted the flights on a "regular" search not using the certificate?
If so there is no relevance. If you want to use a cert, as you later did, those are the only eligible flights for the cert. Nothing is opaque - what you see searching with the cert is what you get.
