Is this for reals? I never knew that was possible.

  Absolutely - in fact, I saw them last Friday. Depending on your airline / how late it is the captain may put an announcement out about it. If you're on an east bound transatlantic red-eye you want to be on the left hand side of the plane, but I think you also have a chance of seeing them on domestic Canadian / Alaskan flights that go far enough north.
