What's the daily tally, and will the airport expect any additional heavies on regularly scheduled routes in the near future?

From what I've checked, it's the daily A330's (NRT/AMS) on NW, and the A330/340 on LH, and maybe others?

And there are apparently LH 346's that make rare, but not regular appearances.

Any 777/747's on scheduled flights coming into the PDX?

I remember the days when UA ran once-weekly 747 service to Tokyo, but that was 25 years ago or so.
