Renderings: The Boeing 777-300ER in United Airlines colors

United Airlines last week announced it would purchase 10 Boeing 777-300ER aircraft. They will be some of the last 777-300s to roll off the Boeing factory line, so United presumably got a great deal on an aircraft that can move a lot of people long distances. United will be the second U.S. carrier to fly the 777-300ER, joining American Airlines.

I just learned from industry sources that these are the tentative delivery dates for the new aircraft:

2016: Dec x 1
2017: Jan x2, Feb x2, Mar x3, Apr x 2

The source also sent some renderings of the new aircraft. What do you think of the look?
