How PIA might be able to save fuel

Since fuel prices frequently skyrocket in Pakistan, Pakistan International Airlines (PIA) should take measures to consume less fuel and make more profits while trying to charge lower ticket fares.
Back in 2005, Air Canada removed most of it's livery to minimize drag force on it's planes to save fuel.

According to the newspaper report this new livery with minimum colors would save them thousands of dollars each year.
Though thousands of dollars a year is an insignificant number for an airline like Air Canada or PIA, it can reduce a huge amount of losses each year.

If PIA were to take a similar measure, the best step in my opinion would be to re-adopt it's earlier livery briefly used in 2004 as pictures below.

While this livery may not be a favorite amongst civil aviation enthusiasts, it would significantly reduce fuel consumption and reduce PIA's losses over a period of years.

Usually, PIA changes it's livery about once every decade.
So if the airline kept this livery for a decade, it could save hundreds of thousands of dollars worth of fuel in that time duration.

The public does complain about un-popular livery, but if this one brings down fares, the public will have little to complain about.
Many passengers will do alot for less fares, even if it means riding on crampy small planes as long as it means having to pay less.
