I've flown a few times this month (Europe, multiple airlines), and on every flight there were verbal warnings and there were also signs at some of the airports when you check your luggage in. I'm pretty sure most commercial airlines and airports are aware of the issue and are making it widely known.

This is going to stick in people's minds – I overhead a couple of conversations where people were a bit confused about whether their phones were safe or not – they knew they had a Samsung, but many people don't differentiate between all the different models.

Same deal when I flew United the past weekend. Samsung Note 7s were not allowed to be turned on or charged on the plane. I think they are taking their cue from the FAA recommendation [0].

This is especially bad for Samsung, I think, because it doesn't just affect folks with a Note 7 -- everyone waiting at the gate hears the announcement. Talk about negative brand associations.

Swiss air flight three weeks ago - same thing. Samsung galaxy 7 specifically mentioned as cannot be powered on during the flight.

Both ANA and Air Canada had a Note 7 announcement at the start of their flights when I flew SEA-YVR-HND-YVR-SEA telling people not to use or charge their phones in flight.

Same when I took a Southwest flight last week. According to the article the guy had turned off his phone just before it started smoking.
