In the 1960s, it took five hours to fly from New York to Los Angeles and only 45 minutes from New York to Washington.
Today, these same flights are more than six hours and 75 minutes, respectively, despite the fact that airports have not changed their location.
It is called "withdrawal time" or "fill in time". And it's a secret that airlines do not want to know, especially because of the negative effects they have on the environment.
That "boxes" (bath, in English) is the extra time that airlines take to fly from one place to another. And given that those flights are constantly delayed, airlines accumulate delays that have experienced their plans for decades, rather than improving their operations.
It may look harmless to the passenger; Ultimately, this means that even if you fly late, you will be pleasantly surprised when you arrive at the time of your destination.
However, the global trend is causing several problems: not only is your journey longer, but also creating an illusion of accuracy means that airlines do not have the pressure to be more efficient, which means that congestion and emissions will continue to grow.
"On average, more than 30% of flights arrive more than 15 minutes late every day, despite the time of withdrawal," says Michael Michael Bayada, president of the consulting firm ATH Group, citing the Travel Travel Consumer Report in the air traffic) of the US Department of Transportation.
The figure was 40%, but that effect – and not operational improvements – increased the number of flights arriving on time. "With towing time, airlines play with the system to deceive you."

He insists that if airlines cover operating problems, users will benefit directly.
"The pullout schedule generates higher costs in fuel, noise and CO2 consumption, which means that if the efficiency of the airline is increased, the costs are reduced, which contributes to the environment and to the rates."
Of course, airlines know that customers appreciate accuracy.
Delta Air Lines, for example, is doing everything possible to ensure that its flights arrive on time more often, according to the US Department of Transportation.
The company attributed its $ 2 billion investment to a new fleet, cabins and airport facilities, but has consistently stressed that "time performance" has increased prices.
So, if the arrival of the weather is profitable for buyers and airlines, why do they not work to be more efficient, rather than prolonging the flight time?
How late is it?
The ultimate goal is "A0", or get to the door exactly at that time. If the flight arrives early or later, it can change other things, such as the availability of the door or the capacity of the airport.
There is even a language that describes this accuracy. Thus, any delay outside A0 adds the number of minutes the plane arrived to the end of the door: A15 for an airplane that was delayed for 15 minutes. But nothing between A0 and A14 is not considered "late" by the Ministry of Transport.

The agency has created a global standard for measuring flights on time, ahead of modern data and communications that make A0 feasible today.
This means that airlines still have the opportunity to arrive "on time" rather than meeting a very specific schedule, which can cause congestion.
Air traffic control must make concessions on this, because if there are too many aircraft arriving at the same time, the airports are saturated. Therefore, air control "expands" the approaches of the aircraft, reducing the rhythms of arriving.
To be fair, airlines have invested billions of dollars in technology to provide more efficient flights for flights, according to Airlines for America. But this did not change the percentage of delays, which are still 30%.
Many things can cause delay, but Bayada believes that 80% of the factors involved – such as timetable, airport flow, ship availability or maintenance – are under the control of airlines.
However, to date, it has been addressed to air control.

"Once the plane leaves the door, the airline forgets this issue until it reaches the next airport"; explains.
Bayada says there is a better option. They could track aircraft and adjust operations during the flight, the choice of order, flight speed and traffic control directions to concentrate in the airspace.
Part of the problem is that the schedule is designed by the airlines for ideal conditions, said Tom Hendrix, executive director of the retired airline.
"But every day there may be changes in the climate, air traffic or the company, and the system needs to be adjusted."
However, Hendrix believes that most airlines can do more to ensure as efficient airlift flows to the airport as it is an integral part of their economic success.
Another option would be to reduce the number of flights, but the schedule of airlines is designed to meet the requirements of the buyer. Then, if there were fewer flights, the rates would increase.
Better late than never
So, is there a solution on the horizon?
One of the biggest assumptions is that the modernization of air traffic control will solve the problem. Billions of dollars have halved delays caused by air traffic since 2007, while those created by airlines have increased, according to a Bloomberg report from 2016.

Bayada has created a system called Business-Based Management (BBFM) for airlines to work with air traffic to make them more efficient.
It was tested in 2012 by four agencies in five airports. And this has reduced the delays, fuel consumption, noise, emissions and congestion, rapidly increasing capacity. Delta saved $ 74 million in fuel alone.
With pressure airlines to cut costs, increase profits and limit their environmental impact, why are they no longer working on it?
"Airlines invested in technology with uneven results," says Hendrix. "Now they have to be very careful in what they are investing."
Hendrix, who worked in Delta when testing Bayad's technology, initially did not want to use the system. It takes some analysis from the Institute of Technology in Georgia to prevent its skepticism. Though he is convinced that he has the potential, he believes he needs more proof.
How does this affect passengers? With airlines that use the system to their advantage, flights are likely to last longer, as more and more flights intertwine through the sky.
"Continuing tactics, such as drag time, have become a common practice for airlines," said travel rights activist Paloma Salmeron, spokesperson for AirHelp.
She believes that this tactic not only allows airlines to improve their times, but also eases their "three-hour magic limit" for postponement, a threshold that qualifies travelers to file claims for damages under European law.
"Many airlines are trying to make passenger complaints more difficult, and the tactic of extending flight times is another way to reduce the traveler's ability to complain and compensate."

Even so, on bath It has not yet addressed the problems of the aviation system affecting consumers.
"Many airlines can improve their efficiency and Bayad's solution is one of them," says the consultant of the airline Bob Mann.
"As for delays and delays, airlines still complain that this is a problem of flight control, but that's not, I think they need to stop complaining and do something about it, in favor of consumers , the employees, the investors and the communities they serve. "
