Embraer developed a new generation of their E190/E195 family to take advantage of the latest generation of engines. The E2 versions of the jets have been quite successful (while the smaller version hasn’t sold, and I think the program is on pause). Embraer has liked to market the jet as the Profit Hunter and has taken to painting their demonstrators up in dramatic liveries to reflect hunting. There was a lion, and the current version incorporates an eagle’s head around the cockpit.
They were taking the jet to Asia for some customer demos, and it routed through Seattle. Initially it came up from Mexico to Boeing Field before continuing on to Anchorage and then across the Pacific. The return came back through Boeing Field and on to Florida before heading home to Brazil. I managed to catch it a little but not always how I would have liked. Still, it was interesting to see it as a different livery always make an airliner look better and this type has not sold in the US, so it is a bit of a novelty for now.
