Leaving SEA this morning I noticed what I thought might be an Air Canada 757 in a "special" livery. It was silver with rust colored detailing and nestled in with the UA flock at the North terminal. I only saw it for a second and didn't get to read the lettering. I'm not even positive on the AC type. Wish I could have figured out how to circle back before getting on the freeway! Does anyone know what is was, or better yet have a picture of this AC?
