In the thread I think you're talking about, they were talking about booking through UX. That threw me off for a bit, but it's actually Air Europa. I don't know much about them, but according to Wikipedia they code-share with SkyTeam airlines. It's probably a mistake fare somehow linked to the code-sharing. You'll also sometimes find mistake fares limited to a certain booking site (e.g., Orbitz or Expedia). Wideroe is a prime example. However, I wouldn't worry too much about that if you just care about getting good or reasonable prices for trips you need to take anyway.
