A feeling of sickness, often including nausea and dizziness, that some people experience when flying in an airplane.
Many passengers experience airsickness during long flights.
Airsickness → It is formed from "air" (from Old English "aer", meaning the atmosphere or sky) and "sickness" (from Old English "sēocness", meaning the state of being ill). The word "airsickness" refers to the state of being ill due to the conditions in the atmosphere, particularly while flying.
Think of being in the 'air' and feeling 'sick' — that's what airsickness means.
