There are several associations in the logo. Firstly, this is the image
of the porthole through which we see the city and its sights; secondly, this
is the "box" maneuver pattern, according to which the aircraft is landing;
and thirdly, this is the letter "A" (Astrakhan), which, as it were, was drawn in the air by a plane taking off. The logo is easily cropped and transformed. This allows you to use its fragments in the design of different media.
