You just went from "the risk for any given Note 7 to catch fire is 0.01%" to "the risk for any given Note 7 to catch fire in the time it takes to fly from Seoul to Australia is 0.01%". Those are very different numbers.
> Would you fly to Seoul from Australia if there was a .01% chance of your plane catching fire?
Given the sheer magnitude of all the other things that may kill you before you even arrive at the airport, let alone the very act of hurdling through the sky at over 650mph in a thin aluminum tube filled with 36,000 gallons of highly flammable/explosive fuel... a phone catching fire is really not much of a factor when deciding to book a flight.
