Emerging economies including India, China, Brazil and Russia will in the future catch up with western aviation travel, according to a sector commentator.
Robin Mannings, an independent futurologist, said that in 40 to 50 years' time such economies will have the same number of planes in the air as other more developed nations and this will help contribute to around four or five times as many craft in the skies around the world.
Those taking cheap flights to India may also be interested to hear Ms Mannings' thoughts on how airports could function in the future.
She said that modern passengers could be "guided personally" by a device which could flag up any potential delays or help make "endless queuing" a thing of the past.
