Australian carriers acted speedily to the Galaxy 7 recall by making the traveling public aware of the issue well before the FAA's ruling came into force on 9 Sep.
The carrier I flew intra-EU with was at the time claiming (so their social media feeds) to be making onboard announcement.
Nothing on 11 Sep, they were doing it on13 Sep saying "don't use/load/look at and DEFINITELY not in your checked baggage" after pushback.
During the entire online checkin (or kiosk)/bagdrop process, there was NOTHING to advise passengers of the risks.
Nothing visible on the airline's website (it's hidden under a second layer "Travel Information" heading and then tagged on to a topic addressing hoverboards. )
Which means that no-one knew not to pack a Galaxy 7 in their baggage.
Heaps of slices of Swiss cheese, the holes all nicely lined up....
(The airline involved wasn't interested in looking into the shortcomings in their processes, btw..)
