If you travel often by plane you may have noticed something. Many times although a flight is delayed, it finally arrives at its destination at the time it was scheduled. But how can we explain that?
To understand this, we need to think about this: In the 1960s, a flight between Los Angeles and New York took about 5 hours. Similarly, the flight from New York to Washington was just 45 minutes away. And yet today, this time of flight has increased instead of being reduced. More specifically from New York to Los Angeles the flight is now 6 hours while from New York to Washington 75 minutes. Of course, airports haven’t changed their position. What has changed is airline tactics.
Because the time windows of flights have a small hole.
The reason? The constant delays. Due to the constant delays of the aforementioned flights as well as other flights, the airlines had to change their tactics. Thus, they have included and incorporated delays into their flight schedules. Instead of improving the schedule and duration of a flight, they have incorporated delays in it.
This explains the fact that although a flight is delayed, it eventually arrives at its destination just in time. They basically make the flight in real-time and at normal speed. This is even surprising to passengers. Because while they may have departed an hour later than normal, they arrive on time.
However, this trend in airlines around the world is causing problems. Not only does the flight last longer, but also in this way the illusion of accuracy is created. So there is no pressure on airlines to become more efficient.
In addition, many argue that longer flights also burden the environment as fuel and noise emissions increase significantly.

Frequently Asked Questions
Airlines have built buffer time into their flight schedules to account for delays. This means the scheduled flight duration is longer than the actual flying time needed. When a flight departs late but completes the journey at normal speed, it can still arrive at the originally scheduled time. This practice explains why passengers often experience delayed departures but on-time arrivals.
Flight durations have increased significantly since the 1960s. For example, the Los Angeles to New York route has increased from approximately 5 hours to 6 hours, while the New York to Washington flight has gone from 45 minutes to 75 minutes. These increases are not due to changes in airport locations but rather deliberate airline scheduling tactics that incorporate built-in delays.
Airlines add extra time to flight schedules as a response to chronic flight delays. Instead of addressing the root causes of delays and improving efficiency, airlines incorporated buffer time into their schedules. This allows flights to arrive on schedule even when they depart late, creating the appearance of punctuality without actually improving operational performance.
Yes, longer scheduled flight times contribute to environmental concerns. Padded flight schedules mean planes spend more time in the air, which increases fuel consumption and noise emissions. Additionally, the illusion of on-time performance created by these practices reduces pressure on airlines to become more efficient and environmentally responsible.
The main drawback is that it creates a false sense of punctuality without improving actual operational efficiency. With no real pressure to solve underlying delay problems, airlines have no incentive to streamline operations or improve performance. This also leads to unnecessarily longer flights, wasting fuel and resources while increasing environmental impact.
