A couple of weeks ago, I was spotting at TPE and on my way home what I'm pretty sure was a widebody flew over my car. At first, I thought it might be Xiamen airlines, but according to Wikipedia, Xiamen doesn't currently fly any widebodies.
It looked like a large twin, and I think it was an A330 (but it could have been a 767). It had a predominantly white fuselage with two blue cheatlines that wrapped around under the nose. One cheatline was a darker blue than the other.
I didn't get to see what was on the tail. It arrived at about noon on a Sunday.
