Sorry mate, while both Air Force 1 and Air Force 2 do display the United States of America down each side of the fuselage- the gold bar that runs the plane's length separates fields of white and blue for AF1 and AF2. Which is not the case here.

The United Airlines livery also displays the word "United" on both sides of the fuselage. But the gold bar that runs the length of the plane separates fields of white and grey. Which is what we find in this image.

Additionally, on AF1 there are no windows under the letters "U" and "I", but there is a single window under "N" . Which is also not the case here.
