Tony C, good find! However as you and I know, what you file and what you actually get are 2 different things. I dont know if flightaware will actually print out the actual route of flight, but there are many times for myriad reasons, that I have been cleared via something other than what I filed across the pond.
Sometimes a random routing may actually be very similar to a NAT track and only offset by one or two points....usually your coast out/in.
