If you are looking for a more sophisticated or poetic way to refer to an airplane, several terms fit different contexts. In a formal or technical setting, "fixed-wing aircraft" is the precise term used to distinguish planes from helicopters or gliders. For a more classical or "vintage" feel, the word "aeroplane" (the British spelling) often carries a sense of early 20th-century elegance. In the world of high-end private travel, you will often hear them referred to as a "business jet" or simply a "vessel" of the skies. In literary or grander prose, an airplane might be called a "sky-chariot" or an "aerial craft." If you are referring to a large, majestic commercial plane, the term "flagship" is often used to denote the pride of an airline's fleet. For a touch of futuristic or sci-fi flair, some might use "skyship." However, in most professional aviation circles, the most common "professional" alternative to the word plane is simply "airframe" or "equipment," though these lean more toward the industrial side of the spectrum than the purely aesthetic.
