Interesting, around this time last year they were talking about *A .
(sorry, the only link I have for that story is in French)

Sounds like they have tried *A, then tried Skyteam and now they are knocking on OW's door. OW could certainly do with more presence in Africa, but TU don't have a particularly large network. According to a poster on another forum they only serve 6 points in sub Saharan Africa: Niamey ; Nouakchott; Ouagadougou; Abidjan; Bamako; and Dakar ( although their website actually only shows four of those as destinations)
I think the fact that in the last 11 months they have talked about joining *A , then Skyteam and now OW suggests that they are not too sure what they want, and are not highly sought after by any of the alliances.
