Does the 25% bonus apply to bux flights

The colors are used to tell which class the airport is, there are 3 classes:

• class 1 (black)
• class 2 (blue)
• class 3 (red)

The main difference is related to where an airplane of a specific class can land: an airplane of class 2, for example, can land just on class 2 or 3 airports.

Once you get a class 2 airplane, you'll use the colored dot on the Jobs screen as a handy way to spot jobs that can go directly to another Class 2 (or better) airport so that you maximize the effectiveness of your Class 2 plane.

You have to have the three separate parts for a plane type in order to assemble it:

• Engine
• Body
• Controls

The plane types must match exactly, so e.g. a Bearclaw-C engine won't combine with a Bearclaw-P body.

When you have all three parts for a plane, the "Build" button at the bottom of the screen will show you a listing of planes for which you have parts, but the one(s) for which you have a complete set you can convert into an aircraft for the right number of bux, which varies based on the plane.
