Bokkenrijder: On another Pprune topic I described my very brief visit onboard the A-319 at Chicago O'Hare (ORD), gate E-7 or E-9.
As stated there, the Captain said that he was formerly with Sabena and the FO was Norwegian, with no time to further discuss backgrounds (during their preflight). It appeared that the Captain was Belgian, although my ear for languages is not too goed.
