I occasionally post fares that I think might be interesting to the BAEC community because they are either exceptionally good or because they originate in the UK (and very rarely both).
As long as the 'rules' about in- or excluding them aren't debated, they are generally limited to the post itself and a few responses. I think it is in line with the spirit of this thread, as long as they are exceptional and somehow linked to this community.
I.e. if EY had a similar sale exUK to Oz, I would mention it (and I did).
