Airlines all set to optimise fuel efficiency (the video is loading, may take long. Please bear with us...)

With fuel comprising 40 per cent of the total cost, airlines, especially low cost carriers are trying to find out means of optimising fuel efficiency. Airlines globally are stressing on adopting various models to save fuel and are also following a strict regime of regular aircraft maintenance including complete aircraft wash, restoring of paint on the aircraft surface, smoothening of dents and projections on the aircraft on a fortnightly basis to minimise fuel consumption.
