Had a lot of great guesses from people on the photo livery quiz. You can see the answers above. Most people made the same mistake I did on the last one. I thought it was USAir, but if you look closely this was a bare-metal plane from American, with Southwest’s livery painted on it. You can read more about these planes and see larger photos on Southwest Airline’s blog.
Nice job folks. There were quite a few others that only got one wrong.
