The price of airfares has risen at a slower pace in recent years as airlines have been forced to cut fares to cut costs, but there is a growing sense that airlines are paying more than they should for air travel.
The number of flights booked per hour has risen to the highest level in nearly two decades.
Airlines are also getting better at finding travellers who will be willing to pay for the air travel and paying for the flights, even if it means a loss of profits.
It may also mean that passengers are getting more comfortable with the idea of booking their own flights.
In an article for The Economist magazine, the economist Thomas Piketty argues that while the cost of air travel is falling, the overall cost of living is increasing.
He suggests that in the past, the average person in the world lived in the Middle Ages, when air travel was much cheaper.
Today, most people live in the modern world, which means they can afford air travel, but it is much more expensive.
Airlines have also had to cut back on their service hours and have to pay higher fares to make up for the loss in profits.
The cost of airline travel has been increasing, particularly in China, where airlines have had to pay more for fuel and more for maintenance.
Some airlines have also been cutting back on some of the benefits that passengers can expect in their flights.
The price at which passengers pay for a ticket on a plane may be rising, but airlines have not reduced prices to make sure that those benefits aren’t being cut.
