'airliner' originates from 'air' and 'liner', where 'air' refers to the atmosphere and 'liner' refers to a large ship or aircraft designed for long-distance travel.

'airliner' changed from the concept of 'ocean liner' to refer to aircraft, eventually becoming the modern English word 'airliner'.

Initially, it meant 'a large ship for passengers', but over time it evolved into its current meaning of 'a large aircraft for passengers'.
