Why planes are painted so often?

It's a constant balance between safety and efficiency. For example, by removing the mica layer previously used when painting its Boeing 737-800s, American Airlines saves nearly 300,000 gallons of fuel annually. Repainting airplanes is also an opportunity for airlines to distinguish themselves from competitors.

Painting an aircraft white helps to reflect the sunlight, and minimize the amount of energy needed to keep the plane comfortable. Modern airplanes that are made from composite materials need even more protection from the sun as they can be damaged by UV radiation, which is another reason why white paint is used.

Additionally, the Pacific Ocean is vast and remote, so if a plane were to go down, it would be very difficult to find.

Because of ram-air heating of the wings. Forward motion of the airplane keeps the wings heated sufficiently to keep fuel temperatures just above freezing. (However, once the fuel flows down into the pipes on its way to the engines, it will start freezing, unless the path is very short.)

The salute also signifies a transfer of control, a change of command if you will, from ground crew to air crew; a symbolic salute from maintenance to say; “Sir/Ma'am, you have the aircraft,” and a return salute stating; “Roger, I have the aircraft.” According to the International Civil Aeronautics Organization and the ...

In order to make the contrast between the brightness outside, and the darkness of the cockpit a bit less, the cockpits were given a bright colour to be less tiresome for the eyes. It's especially useful in cockpits with only a little lightfall from outside, in aircraft like the Tu-128P or MiG-23 and -25.
