Thank you, this post has been very helpful.

For further clarification though, when you say "Shortly thereafter, Airbus recommended all A330s and A340 have either three Goodrich tubes or two Goodrich tubes and one Thales tube in a specified third position. The Airbus recommendation did not extend to the A320." Does this mean it's safe to assume all A330's and A340's have updated these pitot tubes, not just those governed by the FAA and flown by Air France union members?

I am planning my very first transatlantic flight and it is currently on a A330 with Aer Lingus there and on a A320 with Aer Lingus home. All this pitot tube talk is incredibly unsettling.
