The new international arrivals facility at SEA includes a long walkway that overlooks the ramp between the A concourse and the South Satellite. I was able to get a few shots as I wandered through there. A Delta A220-100 was taxiing by when I got there and there was another shortly afterwards. They are pretty common here these days. Since A Concourse is heavily used by Delta, no surprise that a lot of their jets were present. A few Southwest jets were over on B with some widebodies on the satellite.
