There are many reasons why planes must be limited to two lines overhead. The first and most obvious is safety. If there were three or more aircraft in a given section of sky, the likelihood that they would collide increases drastically. Another reason for this restriction is to ensure that each plane gets at least one turn to land without being held up by another plane on the ground below it .
Another reason for this restriction is to ensure that each plane gets at least one turn to land without being held up by another plane on the ground below it.
This rule also ensures a more even distribution of aircraft in the sky, which reduces congestion and allows runways to be used more efficiently. It helps keep air traffic controllers from getting overwhelmed and increases safety margins by allowing them an extra moment before they need to re-route planes as they approach their final destination .
The second most important reasons are economic ones: limiting flights over busy routes could save airlines around $200 million per year because less time will be required between takeoffs or landings . As well, there would be fewer delays due to collisions with other planes.
Supporting Content: It is important to have at least two lines of aircraft when they are over crowded airspace, so that one plane can land without being held up by another plane on the ground below it.

Airlines want their pilots not only trained but experienced; having multiple flight paths makes sure those experiences happen safely and Airlines must be aware of the following limitations when flying over congested areas. – With only one line, there is a higher risk that weather could cause delays or flight cancellations at any given time because planes will have to deplane in emergencies and wait for another plane to land with an empty gate before they can disembark. This would result in significant backups on runways while waiting for gates open up again. – When two lines are available, flights may use whichever line is faster and/or has fewer passengers boarding: this allows airlines greater flexibility when making decisions regarding takeoff times as well as unloading baggage from departing flights more efficiently due to shorter waits between departures and arrivals (for example, if a runway was
