I have had e-mail and phone contacts with more than one WSJ reporters, including Jane, and they have been very professional in their dealings.
But in any case, one does not have any rights to any information that you post here! WSJ or any other person can use whatever you disclose here elsewhere without permission. And even if she did not interview you, there is no problem reporting something factual (using Bearx220's example) e.g XYZ, a Delta ff who posts in Flyertalk re the recent fare sale said "It is a joke."
In my experiences, however, journalists do make contacts both out of necessity (fact-checking) and courtesy.
