The term 'Travels by Air' can be summarized by the word 'wafts', which is a five-letter word. Wafts are a type of movement of air, usually caused by convection or wind. In the context of travel, wafts refer to the movement of an aircraft through the air, typically powered by jet engines. This type of travel is often faster than other forms of transportation, and is used for both commercial and recreational purposes.
