For those who travel frequently, a good seat on the plane is simply necessary, as sitting, for example, in the middle row surrounded on both sides by several "quite plump" fellow passengers is not very pleasant. Or "ending up" in the back row, where there may be no window or seat, is not reasonable, and proximity to the restroom (constant movement and other drawbacks) does not predispose to comfort. Therefore, to have a great time, it is necessary to know where the best seats on the plane are located.
