Airlines order more than 8200 passenger planes in last 5 years worldwide

Begin partial quote:

Asian demand is a big reason why airlines are on the largest jet-buying spree in aviation history, ordering more than 8,200 new planes from Airbus and Boeing in the past five years. There are now 24 planes rolling off assembly lines each week, up from 11 a decade ago. And that rate is expected to keep climbing.

The bulk of the planes are going to new or quickly-growing airlines that serve the expanding middle class in China, India and Southeast Asia.
In Asia alone, Airbus has 1,375 unfilled airplane orders or about a quarter of its worldwide order book.
The low cost carriers are the hungriest buyers. Malaysia-based AirAsia and its affiliate AirAsia X together have orders for 385 new planes. Those new planes alone have enough seats to put an additional 60,000 passengers in the sky at the same time. Many of those planes will make multiple flights a day, sending that figure even higher.

Indonesia's Lion Air has an order for 234 jets from Airbus and another 301 from Boeing. That's in additional to the 107 Boeing jets it currently flies.

They're just two of the numerous low budget airlines that have opened up in the past decade, mostly in Southeast Asia, to service the growing demand for affordable air travel.

Jet mystery unfolds as Asian air travel booms

 

So, despite the missing Malaysian Airlines plane Air travel (especially in Asia) is going to grow much faster than in the U.S. 

I was also wondering with so many planes in the air will there still be enough fuel to fly all these many planes by 2050 at the present rate that Russia and Saudi Arabia might be completely out of oil by then?

Maybe the shale oil deposits or other types of fuel or energy sources will be powering planes by then.
