appears for 15/2, and the time could be correct as well, but beware: there is no location given where the aircraft was picked up on ACARS, so I wouldn't log it yet. The best thing you can do is wait to check whether the return flight was F-GSQK
as well (AF185 if I'm correct).
is one of their brand new ships!
